Dr. Mark John Hausknecht
Mark Hausknecht MD, 65, a renowned Houston cardiologist died suddenly on Friday morning July 20, 2018. Beloved son, husband, father, brother, physician, colleague, and friend to many, he personified the ideals of compassion and service. The man who healed so many hearts during his life, has left so many broken by his death.
Mark was born to Catherine and the late Otto Hausknecht on March 23, 1953, in Weymouth, Massachusetts. He earned his undergraduate degree at Cornell University and received his medical degree from Baylor College of Medicine in 1980, where he met his future wife. He completed his residency and fellowship at The Johns Hopkins Hospital in Baltimore. Dr. Hausknecht was a practicing cardiologist at the Texas Medical Center since 1987. Patients from all walks of life felt a special bond with Dr. Mark. Listening and taking the time to explain things to each patient, earned him their gratitude and affection. He, in turn, felt honored to be their physician.
Mark was driven by insatiable intellectual curiosity but found relaxation through physical labor. He was a voracious reader, pilot, chef, DIY repairman, beekeeper, recycler, urban gardener, cyclist and lover of music and the arts. It would not be unusual to find Mark solving physics problems or differential equations on vacation. Attracted by the concept that "one's mind determines one's destiny," he became a practicing Buddhist in later years. Meditation was an essential part of his daily life.
Mark loved his family and was proud of his sons. When the boys were young, the years spent as the Scoutmaster of BSA Troop 11 provided some of Dr. Hausknecht's happiest memories. With the Troop, Mark shared his appreciation of nature and the obligation he felt to preserve it. He instilled a strong work ethic, self-reliance, and a love of the outdoors in his sons.
Dr. Hausknecht's keen intellect, quick wit, infectious smile, and delicious BBQ will be deeply missed. He was a leader by example, a teacher, a role model, and an inspiration to many.
Mark is survived by his wife Dr. Georgia Hsieh, sons Matthew (Man) and Paul, mother Cathy, and siblings Peter, Susan (Tom), Amy (Steve), five nieces and nephews and his mother-in-law, Grandma Rose. He is also survived by three rescue dogs who miss him dearly.
The family would like to thank law enforcement for their diligence and is deeply grateful for the outpouring of love and support from so many. There will be a memorial service at First Presbyterian Church, 5300 Main Street, on Saturday, July 28, 2018, at 10:00 am. In lieu of flowers, the family requests donations be made to one of Mark's favorite charities (listed at or one of your choosing. Please share your memories of Mark at his online obituary at

My father, Frank Dover, was a patient of Dr. Hausknecht for over 30 years and I truly believe he added so many years of life to my Dad. My father respected Dr. Hausknecht's opinion so much that he wouldn't have any procedure (heart or non-heart related) without first talking to Dr. Hausknecht. A truly kind and compassionate man who never made you feel rushed and a heck of a doctor. The last time Dad visited him was in March to discuss whether he should start Hospice. Dr. Hausknecht had a long talk with my Dad and when he left, they hugged and he told my Dad - Goodbye old friend. My Dad passed away a few weeks later and it is ironic that Dr. Hausknecht passed away on my Dad's birthday. I am grateful Dad didn't have to know about the travesty that befell his wonderful doctor - I don't know if his heart couldn have handled being broken. The world has lost a wonderful man and our thoughts and prayers are with the family.

Among so many remarkable friends I made at Cornell and Sigma Pi, Mark was a truly extraordinary person. His intellect, sensitively, kindness and humanity set an example we all could hope to emulate. I am heartbroken for his family, patients, colleagues and friends. We have all lost a very special person in our lives.

There are no words to express the loss of Houstons finest Cardiologist - Dr Mark Hausknecht. He has been my physician since 2007. In 2016 he gave me my life back with a pacemaker implant for Christmas. You will never be forgotten and forever in my heart.
My deepest sympathy to the family. Forever in my prayers.

My deepest condolences .
He was the best Doctor who walked on earth. I felt a terrible loss upon hearing of his passing. Dr Hauschnect saved my mother's life.
Mrs. Olivares is alive today because of his determination to try everything in his power to save her life. My mom is a double amputee but she is alive. He was my physician also along with other family members. We had the most respect and trust in his care.
It was amazing how he.could remember small details of the family.
I will always keep you all in my prayers . May God bless you

An angel on earth was taken from us. I know Mark, Gigi, Matthew, and Paul through First Presbyterian Houston and our adventures in Boy Scouting. Mark is the most gentle, kind, caring person I think I have ever known. As a leader for our boys in BSA he set the ideal example of the kind of man we all hope our sons will become.

After tearing my ACL on one high adventure in the Boundary Waters of Minnesota, we took the boys on the next year's adventure of a hiking trip in the High Country of Yosemite. Unfortunately by the end of the trip my repaired knee decided my hiking time was over. Mark organized the boys to break up my pack between them and personally guided me down into the valley to be sure I did not fall and sustain injury. All this in a kind, persuasive manner that I am sure is what all his cardiac patients recall for his "adventures" with them.

God bless you Gigi, Matthew and Paul. You will be in my prayers.

As a former employee of Houston Cardiovascular Associates I have so many wonderful memories of Dr. Hausknecht. Dr. Hausknecht was more than a gifted surgeon, he was also an outstanding Boss. He was always fair, compassionate and direct when necessary and I had so much respect for him as a Physician and a Employer. Dr. Hausknecht was also my Mother and my Husband's Cardiologist and he provided the absolute best and most humble and compassionate care that anyone could ever ask for. My family and I would like to express our deepest and most sincere condolences to Dr. Hausknecht's family, colleagues and his entire staff at Houston Cardiovascular Associates. Rest In Peace Dr. Hausknecht. The world has lost an amazing and gifted healer of hearts!

During our early teens, for too short a time, Mark was my best friend.
And of all the activities we enjoyed together, one of our favorites was riding our bikes everywhere! One event in particular stands out to me, not only because it was a grand adventure, but because it, and Mark, changed me for the better.

We couldnt have been more than 14 years old when he proposed that we ride our bikes from our suburban community all the way to downtown Cincinnati and back again a trip of 28 miles on busy city streets and through every kind of neighborhood. Knowing Mark, I believed he could do this, but I certainly didnt think I could; I told him I was afraid and that I wouldnt accompany him.

Instead of making fun of my fears (as just about any other boy our age would), he encouraged me. He built up my confidence; this was a ride I could do if I focused on the positive and trusted in myself. Wed watch out for each other, take turns leading the way, and together accomplish something we would always remember.

It was daunting, we did it, and it was a wonderful day.
To someone else, it may have been just a bike ride. To me, it was a lesson in courage that Ive never forgotten.

And thats what made Mark so special to me. He didnt doubt himself, and he inspired those he cared for to reach out further, to extend themselves and achieve something worthwhile.

I have never written on legacy, until now. I feel the need to add to the wonderful things being said about this man. Dr. Hausknecht was my doctor years ago when I had done damage to my heart trying to starve myself to death. I was listed as anorexic, but I was not. I truly was tired and didn't want to live anymore. I ended up at Methodist ICU cardiac unit. Dr. Hausknecht would come everyday to see me. I could tell he was so sadden about my physical and mental condition. I knew he cared, and knowing that people like him still existed gave me a little hope. I had a long way toward health and healing, but the doc was definitely a factor. That was twenty years ago, but Inever forgot him. Recently, I had a heart issue scare. Although I went to a doctor in my area, in my mind I already decided that if turned out to be serious, I wanted to see Dr. Hausknecht.
I am crushed to hear of this and saddened that the world has lost such a special man. That said, what a gift we (those he touched) were given.
God bless your beautiful soul Doc.

While at Hopkins we became friends. I remember you and GG came to the house before you moved to Houston to check on me. And when you and the family came to visit us in Westminster and we laughed because we had the same car. My prayers are with the family but my memories of you will last my life time. God bless all of us that have lost a truly unique person and a good man.

Our hearts break with the sad news of such a great loss. Mark was a wonderful and thoughtful roll model for both our sons in troop 11. Mark's time as a Scout Master at FPC BSA troop touched so many. John, my husband, recalls the time he first met Mark. He told John during his time as a volunteer, he will receive much more than he could give and Mark was right. It was an honor for John to serve with Mark. Our sons were the lucky ones to have not only a knowledgeable, skilled, passionate leader but also one who was a thoughtful and steady guiding light for our sons to look up to...a man to aspire to be.
Thank you Mark for your leadership, your troop 11 family will miss you and will always hold you, GG, Mathew and Paul in our hearts.
Our thoughts and prayers are with you

I retired a month ago after thirty five years of nursing. Dr. H was one on the top two docs I knew and worked with. I knew him first at Methodist the Memorial Hermann. I loved doing cardioversions with him. After a period of time once when he was not around, we were told he was ill. Once he came back I said to him he looked so good, he blushed and said "I don't know about that". What a kind and a gentle soul. So very sad. Ellie Neberman RN.

Dr. Mark was a savior angel to us. He healed my husband Tom from severe heart disease and became a dear friend during our many subsequent visits with him. He and Tom spoke about a special trip to see Tom's antique cars. We will dearly miss him.
With sadness and love in our hearts for him,

I was a freshman when Mark was a senior. Sigma Pi had an intercom in the phone room so that we did not have to run upstairs to get someone when there was a call for them. One day I walked by the phone room and Mark was saying the most ridiculous things into that intercom...and someone from an upper floor was answering him in kind.

I knew he was premed and brilliant. I learned from that moment...that being playful, ridiculous, and fun is to be encouraged, and is not an indicator of intelligence or lack thereof.

Mark was open and kind and welcoming to us squirts who were trying to figure out who we were. I looked up to him.

Sigma Pi Reunion 2014
I am writing on behalf of many brothers of the Sigma Pi fraternity at Cornell University. Mark attended Cornell from 1971 through 1975. Many memories of Mark have been shared among his fraternity friends over the past week. I would like to share a few of them, since they capture the college-aged man that we got to know and love. In these memories, which have been edited, "The Ponderosa" refers to the house on Lake Cayuga, near the Cornell campus, where a number of the fraternity brothers lived, including Mark, or "Knecht" as a number of his friends called him.

"Knecht had an uncanny ability to gracefully and confidently get himself into and out of trouble. He loved driving the Cass Park Expressway in his little Vega. This was the walking path in Cass Park on the way to the Ponderosa complete with wooden bridges up and over the small streams. His car just barely fit between the hand rails of the bridges. Priester and I picked him up at LAX to attend Bert's wedding. Knecht was a part of the wedding party and due at the rehearsal and the rehearsal dinner. He was deep into Med School at this time and had just flown in from Houston. I'm taking a break, no one is telling me what to do. So, a trip to Venice Beach, some food, a few(?) beers, then watch a long UCLA based parade. We got separated somehow, Dick & I lost him. We searched through the crowd, we climbed on top of a bus shelter to look for him and hoped he would spot us. He found us all right- he had climbed onto one of the last floats which was sponsored by the UCLA Alumni he was entertaining the crowd and waving to everyone. A fun loving, brilliant man; a life well lived. I cherish my memories and my time with him." -- Casey Forbes

"I sat down this morning to catch up on my emails and was shocked to hear such sad news. I'm trying to shake it off and remember Knecht. He was a caring person that I was fortunate to have as a brother, a friend and a housemate at the Ponderosa. I'm so glad that we all got to see him again at the Centennial Celebration. I remember Knecht thinking he could eat 3 dozen glazed donuts in one sitting. I think he just saw the movie Cool Hand Luke where Paul Newman tried to eat 3 dozen eggs. Many more memories will come back as I think about him.
We all lost a great person. " -- Steven Sanford

"After sitting down and shedding tears over the loss of our brother and fellow housemate at the Ponderosa I, as I know many of you are, am numb. Knecht's intellect, wit and freindship was so special to all of us in that mid 70's group. Where does one begin to describe such a comrade that carried himself with eternal 'still water runs deep' demeanor and class. He could recite chapter and verse of Firesign Theater, play cards until dawn with 'pecker' the delusional caged bird close by and then proceed to ace all of his Pre-Med Big Red courses. Correct me if I'm wrong Ponderosans, but he had the 3rd floor attic room on the lake and was one of the more active participants in water ballooning passing tour boats... I'm just sayingThe same 1st class derelict who treated GHW Bush....God's speed Dr. Knecht, it was a privilege to know you, be your friend, housemate and brother." -- Sandy Kraker

"I was so sorry to hear this news. I had the privilege of being Mark's roommate our sophomore year in the house. He was incredibly bright and hard working, and had an incredible sense of humor. I remember when he was a math major before he decided to switch to pre-med. There was never a doubt in my mind that he would make it all the way and be successful. What a great loss." -- Peter Phillips

"I'm stunned and saddened by the tragic loss of our friend and brother. As a premed I recall taking classes like Organic Chemistry with him. He aced itthat was Mark. My deepest condolences to his family. " -- Jeff Craver

"Knecht was a compassionate derelict-scholar who was always happy to see me, impart humorous wisdom, and just be his loveable self as I struggled to find myself at (Cornell U). I am sad at his untimely death and (upset) at gun violence in our country." -- Pete Cady

"I guess I'm in good company with George HW Bush; Mark Hausknecht saved my life once also. One spring day back in '75, after getting properly "prepared", Mark and I took off from the Ponderosa in my Sunfish. The wind was probably blowing 20 knots. Even though the weather was nice, the water was still about 35 degrees. We tipped the boat over on a tack, and probably flipped it 3 more times before Mark was able to climb on and stay on. I had on a heavy sweatshirt, and by then was so waterlogged and enervated that I couldn't pull myself up onto the boat. Somehow, Mark had enough energy to pull me back on, and we reached back over to the west shore, ending up half a mile or so south of the 'Rosa. We begged some kind lady to let us in and use the phone, and Sandy Kraker came and took us back to the 'Rosa. Thank you Mark; we will miss you." -- Mike Quaid, '75

"I am so sorry to hear about Mark, such a tremendous person with so much to offer and has given so much, and such a senseless act. Mark. our prayers are with your family. I am proud to have known you. I just talked to Knect a couple months ago when we drove through Houston on the way to see my son. It was great to reconnect. I also was a part of many a Cass park express adventures in the vega, with the additional adventure of an icy night coming in from the rosa and fishtailing off off about 4-5 cars on 89. May have been the last vega adventure. Knects skill at driving though was truly shown with Ceciles manual,throttle control.
Going back a few years to Freshman/sophmore years, I do remember while all were drinking cheap beer, Knect went for the much higher class Sangria, I'm having one now in his honor." -- Willy Dougherty

"So many great memories, albeit a few a little fuzzy as well. Although not ever a resident of the Rosa, I did appreciate the many rides back and forth to the house. One of those was with Mark and included a shortcut on the Cass Park Express in a little car owned by Cecile. Great ride! Great wit and dry humor. I will always look up to Mark. So sad, indeed, and an absolutely senseless loss. He made us all proud to know him. He will be missed. " -- John Stetson

Our father and step-mother were blessed to have Dr. H. as their longtime physician. For many years our family relied on his skills, guidance and compassion. He always took the time to explain his recommendations. In our times of loss, he grieved with us. The medical profession and those who admired and love him have lost a great man. The Jircik Family

My husband is a heart transplant patient and Dr. Hausknecht was his first heart doctor. They met 30 years ago. Dr. H was a "one in a million" type of doctor. He was so special and the kind of person you always looked forward to seeing. He spent time with you and you knew he cared. After my husband moved to a team of transplant doctors, Dr. Hausknecht would still check on him and was always glad to see him. Dr. H was my doctor and I recommended him to many of my family members and friends who also became his patients. Out thoughts and prayers are with his family and staff. We, like many others, are going to miss him very much.

Dr. Hausknecht was truly a compassionate man. When I came to see him and he told me I had cardiomyopathy, I asked what does that mean and he explained. I was by myself and stunned, I started to cry. He came around the desk and hugged me until I could gather my composure. He comforted me and said my dear you are in good hands and we will do everything to fix this. He scedualed a heart cath. I needed a stint, there my brother was with me and we were in awe of his compassion and thoughtful skill, very grateful for him we expressed. He quoted " If I have seen farther, it is because I have stood on the shoulders of Giants" we marveled at such grace my brother and I. Just as the week before his passing I was in his office ready for another heart cath. He said you know me, I believe in getting to the root of the cause. I'm so heart broken that this could happen. May God Bless you and keep you in His loving care Mark Hausknecht and to your loving family.

Dr H was an outstanding teacher and mentor. He was brilliant with facts and critical thinking, but he taught more than book learning. He was the first person to teach me one of the toughest lessons of being a doctor - sometimes it's hard to cope with sad outcomes when you are emotionally invested, but if you aren't emotionally invested, you probably aren't doing this doctoring thing right.

Dr Hausknecht's passing is a huge loss to everyone. My deepest sympathies to his family.

I first met Dr. Hausknecht when he treated my mother and inserted a pacemaker for her. Every time she was in the hospital for other ailments he would come by to check on her and look at her ankles for edema. My 84 year old mother would giggle and tell us all (in front of Dr Hausknecht) that he just liked to look at her ankles. He would just smile and shake his head. A truly charming man who later also became my doctor, my partner's doctor and a neighbor in Old Braeswood. He will be very much missed.

Dr. Mark Hausknecht placed a stint in a very precarious place in my husbands heart several years ago. Because of the stent, my husband didnt have to have open heart surgery. He also treated me for afib and blood clots. After cardioversion the meds he prescribed for me have kept me from expirencing afib or blood clots again. He was a patient, caring, relatable, brilliant man and doctor who treated everyone with such respect regardless of whether you were a CEO or an old couple from The Woodlands. Houston has lost a wonderful doctor, husband, father, brother, sister, son, uncle, and friend. Our hearts are truly broken for the loss of this doctor.

Dr. Hausknecht was an outstanding, kind and personable physician, and he was adored and revered by his patients. I was a long-time cardio patient of his, and he always knew instinctively how to allay concerns and fears, no matter how long the diagnostics process was, or what the end results were.

He was the kind of physician who personally called you at night with test results, and always had a consultation with you at the end of a long day of myriad procedures. His compassion and attentiveness were such that you felt as if you had your own private physician. Every patient I ever came across felt the same way.

His patients, his colleagues, and his loving friends and family are all suffering a tremendous loss in his death. My deepest condolences to his family, and to all of those who knew him personally. You are in my continued thoughts and prayers.
