William N Hamstra, DO

My daughter needed a port removed last minute as she was leaving town the next day. He got us in last minute and I know that sent him home very late. He took a lot of time with us and we didn’t feel rushed at all. He and his staff are very personable and put her at ease instantly. Very grateful for him fitting us in and doing such a good job with her procedure.

Over Thanksgiving I found myself in great pain. This was nothing I had ever experienced and after a quick visit with my own doctor, I was in the capable hands of Dr. Hamstra. He immediately saw me and helped to determine a medical plan along with my input. Surgery for gall bladder removal followed with excellent results. I cannot say enough about his calm and reassuring bedside manner as well as his surgical technique. My scar is so small as to be invisible. I also appreciated his office staff who were very attentive to me as I was dealing with logistics while also dealing with pain. They were wonderful.
So, I wish I didn’t need the surgery, but if it was to be, I couldn’t have been more pleased that the care I received from Dr. Hamstra.

I went to the ER in San Ramon with terrible pain in my gall bladder. I wasn’t sure what I wanted to do. I had had terrible reactions to anethesia and thought if they put me under I would never wake up. Dr Hamstra had a calm and friendly manner, explained the procedure to me and answered all my questions. He joked a little with me, and made me feel like I could trust him with my life. My bonding with him made a world of difference in my decision to go ahead, I was very thankful because in reality I had no choice. My situation was life threatening. I told him of my sensitivities to drugs and he took it very seriously, and described the competence of his assisting anesthesiologists, who also reassured me before we went into surgery. He gave me choices of how I wanted the surgery done. I couldn’t have had a better experience. I had no reactions or side affects to any medicines or drugs. I didn’t even need any pain killers after the surgery. Both Dr. Hamster and my Anesthesiologist both came to visit me in the hospital the next day and I was released that night. I very highly recommend Dr Hamster to anyone that needs surgery, and I want to thank him for being there for me with real concern and quality care. Judith Shadzi

I selected Dr. Hampstra to handle my surgery, which required the removal of my gall bladder during a procedure to remove a tumor from my right kidney, because he was so highly rated by the doctors in my medical group (John Muir Medical). I have to say I was not disappointed.
Dr. Hampstra is not only extremely knowledgeable, but he is also extremely accessible. After the surgery when I was have some pain issues, he gave me his personal cell phone to contact him if I needed more medications. He also followed up with me on a early Saturday morning to check on my status. When I answered the phone, he said, «Hi Mike. This is Bill.» About the only thing he did not do was a house call, but I would not have been surprised if he had shown up at my door.
This man is one of the most personable men in the medical profession, and although I hope to never have to utilize his service again as a surgeon, I could not recommend anyone more highly.

Dr. Hamstra is an excellent surgeon but what is even better is his bedside manner and follow up. He takes the time to talk to you and explain everything and answer ALL your questions. The biggest compliment I can give him is I would send my children to him and my primary care physician says the same thing.
