Dr. Ostrowski was the Best Dentist, you could ask for. He was professional, honest and kind, and someone you could trust. He took me right away when I called in for an emergency.

I am in shock over the sad news of Dr. Ostrowski's passing. I found him to be a kind and gentle dentist, with a great dry sense of humor.
Our sons were in classes together at Goldridge Elementary.
Blessings to the family as you heal this tremendous loss.

Oh my goodness. I only just now discovered that Dr. Ostrowski left us. Such a sad thing to know. He was a kind man-- a top-notch, fair-minded professional. He graced this world. Adios, Dr. O.

I often thought how grateful I was that my husband and I were so much older than Dr. Ostrowski, that we would be able to go to him forever. We will really miss seeing and visiting with him. He was top notch, a radiating island of happiness that seemed to cheer everyone. So pleased he was in our life.

Our lives were richer for knowing you, our smiles brighter and our laughter heartier!! Thank God for crossing our paths even though for a short time. May his angeles carry you and keep you company in your soul's journey!!

Honey, every single moment is spent missing you. I long to hear your voice, hear your laughter, kiss your lips and feel your warm embrace. I never imagined that my tomorrows would be without you so soon. I love you so very much, Douglas Chester Ostrowski, my forever love.

I was trying to contact Dr Ostrowski while he was away on vacation because my tooth hurt. I was waiting for his return because he is the only one I trust. I was devastated by the news - I just took for granted that he would be there for me. He was the best dentist I have ever met and a lot of fun to talk to. He would get me laughing even while he was working in my teeth! I am going to miss you very much Doug.

Part of me is heartbroken, part of me is worried no dentist can take his place. He was outstanding and compassionate, with a wonderful sense of humor. I was raised with an old fashioned dentist who found children inconvenient at best. Dr. O helped me get over my great fear of dentists and I will ever be grateful. My own kids were raised with Dr. O and have none of my fears. I am sorry to have missed his memorial party. My heart goes out to his wife and kids.

We were both shocked and saddened to hear about Dr. Douglas Ostrowski passing, and we regret not being able to attend his memorial - we received notice on the day it occurred, and after our mail was delivered. My husband has been seeing him since he started around 1985 and the first thing he did was extract all 4 of his wisdom teeth. Ever since then, for over 30 years, he has been seeing him every six months. I have had no problems since 1983 due to his teachings on how to keep them healthy.
For myself, approximately twelve years, and I knew the day I went to him, I would be in excellent care. He is a Professional in every aspect and I looked forward going to see him, every six months also, and I improved in caring for my teeth from his explanations at each visit.
Another thing, he shared with me is that he made the pies for Thanksgiving dinner and was pretty proud.
May God bless his family and Rohnert Park community members who diligently were under his care.

I'm truly saddened to hear of Doug's passing. He was the reason I became a dentist. I worked as his assistant for several years and through observing the kind and competent way he delivered dentistry, I was inspired to become a dentist as well. He made a difference in SO many people's lives and he was taken way too soon. My heartfelt condolences to his family...

So sad to hear. One of the best old fashioned professionals of our time. Our dentist for over 30 years. Once traveling out of state I had an emergency tooth ache. He treated me from long distance and met me in his office off hours to fix it when I returned to town. The best in his class, gone before his time. You will be missed.

To the loving Ostrowski Family and devoted
Office Staff: In my very long life, I have
had many dentists. None have been more skilled, more connected to his patient and
more conscientious and effective in dental
artistry than this doctor. I have enormous appreciation for his ability as a dentist,
but even more do I wish to acknowledge his
kindness and genuine warmth. He is a great
loss to all who were blessed by his caring.

My family and I just found out today that Dr. Owstrowski passed away. My heart sank when I found out. He was my favorite dentist and tended to our dental needs for decades. He was like family to us and my kids never feared going to the dentist (like I did before meeting Dr. O). RIP and my condolences to his family.

Dr. Ostrowski was the best dentist ever. He worked on my teeth for twenty years and always preformed miracles. I always felt safe and well taken care of. The office was a family. I received the letter yesterday and was devastated. He was a pillar of strength for all of us who counted on being taken care of professionally and fairly. I don't even know how I find anyone to replace him. Condolences to the family. Good man!

My family and I were so shocked and saddened to hear of Dr. O's passing. He was truly a man of honor. We always knew he was going to be kind, gentle and trustworthy. I've had a bad history with dentists, but as soon as I started seeing Dr. O, he put me at ease. We loved his sence of humor! This is such a loss for our community--he just always made us feel like he was our small towns dentist. He cared about each person in such a special way.
My heart goes out to his dear family❤ May you find comfort and peace knowing he is with the Lord in paradise.
Thank you Dr. Ostrowski for your many years of kindness. May you rest in peace.

My deepest sympathy for Dr Ostrowski's family and friends. He was my dentist for over 20 years and always took care of me, my family and friends. I recommend him to everyone I knew because he was the best and kindest person. I'm saddened that he was taken at such a young age. He loved his family and put his kids through college before he could retire he was taken to early. I'm truly blessed to have known him and have him as my dentist. He had the best staff. Everyone was family to him because that's the kind of guy he was and they love him. Thank you Dr O for taking care of me for all these years. May you Rest In Peace as you watch over your family.

Words can not express my heart felt sympathy to Dr. Ostrowski's family. He was the best dentist anyone could ever have. He cared about his patients and not the money a very rare quality in todays society. I will miss him dearly!! He was so funny and always had a welcoming smile that would put anyone at ease. There will never be another dentist like Dr. Ostrowski. I believe God broke the mold when he made this man. May you rest in ever lasting peace dear friend. God Bless you and your family.
