In Loving Memory
Patrick J. McMahon, M.D.
April 12, 1955 - July 22, 2020
Beloved Patrick McMahon died in his sleep Wednesday, July 22, 2020. The kindest and gentlest of men, he was loved by many. Pat decided to leave on his terms in a place he wanted to be – not in a hospital or operating room. His wish was respected. The cause was cardiac complications.
Patrick was born April 12, 1955 in Portland to Fred and Marian McMahon. The youngest of five children, Pat shared this special bond with his identical twin brother, Mark. He often noted he was the youngest (by 5 minutes). Raised first in the Alameda District in Portland, the family moved to Raleigh Hills in the early 60's, where he attended parochial schools through Jesuit High School. Patrick attended the University of Oregon, graduating Phi Beta Kappa in 1977. Pat received his MD from Oregon Health Sciences University in 1981 and completed his residency at the University of Connecticut Health Sciences in Otorhinolaryngology (ENT) in 1986. With an opportunity to move back to Oregon, he jumped at the chance and began his career in medicine as a Physician/Surgeon with Northwest Permanente. Pat briefly went into private practice at the Broadway Clinic in 1988-89 before returning to Kaiser Permanente, admiring this medical model of practice for his specialty of ENT. Pat often commented that the root of the moniker 'physician' is "to teach" – and he loved to teach and inform all willing to listen and learn. His knowledge extended well beyond medicine and science, into economics, culture, and politics. And of course, the proverbial 'fun fact'.
Patrick met the love of his life Cindy Slater at the University of Oregon. They married in 1979 and had three amazing children: Melissa (Tom), Tessa (Casey) and Conor. Pat loved his family fiercely and forever had their backs. He made them better, made them laugh, and made them just. Pat was always present with a story or words of wisdom. He had so many stories that they became numbered as they had been repeated throughout the years. Pat had a tremendous humor and a great ability to turn a phrase succinctly spoken with gentle glee as only the Irish may do. His stories were often accompanied with a good glass of whiskey. Pat was a man you could trust with confidences you could not share with anyone else. A dispenser of heartfelt care and advise.
Pat McMahon loved the outdoors and found his happy place at the family ranch near Trout Lake, Wash. He was as skilled at manual labor as he was with the refined finesse of a surgeon. Pat was persistent and always game. He enjoyed the frustration and delight of golf at Portland Golf Club, a place he grew up caddying at and ultimately becoming a member. He was an amazingly beautiful water skier and snow skier – dancing on water in any form. Pat loved boating and through the forty years of marriage, Pat and Cindy always had a boat. With great times on the Connecticut River and continuing on waterways throughout the Pacific Northwest.
A celebration of Pat's great life will be held at a later date when COVID-19 restrictions are lifted.

As colleagues we had great respect for Pat. Also he surgically repaired our son's nasal fractures. Indeed he was a compassionate and skilled physician; a loss to all.

I recall how Dr. McMahon went the extra mile to come back to Beaverton Urgent Care at night to see patients in need on the spot. He was a kind physician and colleague and is greatly missed. My prayers are with his family.

My condolences to Dr. McMahon's wife and family. I did not know him but he sounds like a lovely person and anyone who knew him was fortunate to do so.
I share his wife's pain as my husband of 29 years passed away at home from cancer on July 19, 2020. I have much empathy and sympathy for her and all the family during this very difficult time of loss. May God bless you.

I had the distinct pleasure of working with Patrick on many occasions, providing anesthetic care to his patients in our surgical operating suites. He was a skillful surgeon and a strong advocate of the safety and well being of his patients.
Patrick was always kind, courteous and respectful to all the staff and colleagues. He was a gentleman in every sense of the word. RIP, my dear friend.
My heartfelt condolences to you Cindy, and to all the members of the family. May the happy memories of your life together provide you comfort and peace.

I had the good fortune of working with Pat in the clinic at Beaverton and then WMC.
He made work as much fun as possible. I was always glad when he was in clinic. His patients loved him. He made them feel listened to, respected and cared for. He never rushed their questions. I think the staff felt the same way about him.
Cindy, I am so sorry for you and your family's loss.
I feel so lucky to have known him,

When Pat covered pediatric ENT inpatient consultations, I was always grateful for his depth of knowledge, his gentle and caring manner with children needing surgery, and his calm reassuring manner with their parents. He patiently answered everyone's questions and instilled trust. He would have made a great pediatrician.

While reading Dr. McMahon's obituary I noted that we had some cross-over years at UCONN (OB/GYN) & my good friend Dr. Lori Spilove (now Garris) was an ENT resident at the same time. I sent her a copy of Dr. McMahon's obituary notice & she wrote the following and I thought you would like to read it:
"His photo jogged my memory. His face was thinner, his hair was darker and longer, but his eyes and smile were the same. He was actually a year ahead of me and was very upbeat, energetic and kind. He encouraged me and always had a confident, self-assured, no-sweat demeanor with every emergency. He set a great example of how to be calm under pressure, which I continue to emulate even today. "
My condolences to you. I didn't meet Dr. McMahon, but who knows, we may have passed one another in the OR or halls of UCONN. Diana Bell MD

To Cindy and the kids, my most sincere condolences. I was one of the nurses that worked in the OR with Patrick. And I loved every minute of it. I also had the privilege of baby sitting for the kids a couple times. And I know you all came to my wedding reception in Hillsboro in 1998. Remember," Grief never ends . . . but it changes. It's a passage way, not a place to stay. Grief is not a sign of weakness, not a lack of faith . . . It is the price of love." Debra

I worked with Dr. McMahon at the old Bess Kaiser Hospital on Greeley. He was so wonderful in the OR, and I loved working with him. Truly a gentle giant. He was always kind to patients & staff alike. I am so sorry to hear of his passing, so young. May I wish his family peace and healing - we've lost a good one!

For years, I'd regularly run down the stairs from Beaverton Pediatrics to ENT in the basement, hoping to ask Pat about a child's needs. Without fail, Pat was generous with his time, advice and good humor. When I think of Pat, a smile comes. May you be comforted by his good memory, keeping him alive in your hearts.

Dear McMahons:

I am so sorry and we'll light a candle for your father/husband at Jesuit for him. This is very sad and what a tribute for you to recognize him as a father that "made them better, made them laugh, and made them just."

Our prayers and shared belief in the home he now shares.

I was fortunate enough to practice pediatrics at the Beaverton clinic just upstairs from Pat for many years. He was always my go to guy because no matter how busy was he would take a moment and help. Not only was he super smart but he was so sweet and kind and Made going to work a pleasure. My best to his family

He was a great doctor and colleague. From the time he diagnosed my acoustic neuroma in 2001 to the time he retired I saw him regularly. He was always cheerful and had a smile. I couldn’t have had a nicer, kinder physician. I will miss him. Steven Sandor MD

I was one of Pat's partners at Kaiser for many years, albeit on the other side of town at Sunnyside. I appreciated his sense of humor, his openness to discussion, and his overall gentle manner. Over the years, he and I collaborated on cases during which time I saw his true caring for patients. He operated on me at one point and I was grateful for his good work. He will be missed by all who knew him.

Dr McMahon did sinus surgery for me back in 1996. It was truly life changing. I think I would have been long dead if not for this surgery. Thank you Dr. Pat. One of my favorite Kaiser Doctors, you could tell he cared about his patients.
I am so sorry to hear he is gone. He had a lot to give.

It was an honor to work in the operating room with Pat for more than 20 years. Always a gentleman, with a pleasant and respectful manner. Wonderful sense of humor every day regardless of the circumstances. I always looked forward to giving anesthetics to Pat’s patients because that meant it was going to be a great day. We all shared stories of what was happening with our respective family members. I will never forget the humorous smirk on Pat’s face and the twinkle in his eyes. Our deepest condolences to the McMahon family.

I've missed Pat's presence since he retired, and miss him more knowing I won't get to see him again. He was a mentor to me early in my career, and supportive during hard times. His laugh, often loudest when telling his own stories, is something I will never forget.

This obituary did a far better job at giving a sense of this special person than any words I ever could have used. I had the privilege to get to know Pat and Cindy while Pat attended UConn and lived in the town I grew up in. Those times were some of my fondest memories and my sense of loss hasn’t diminished because of the years passed.
