Outstanding surgeon and exceptional Doctor.

Dr Hamstra performed surgery on my son after his appendix ruptured. He took the time to talk us through the procedure, possible risks and what actions they would take if problems occurred. The surgery was a success despite the complications created when the appendix ruptured. Post surgery he stay closely involved with our son and helped my wife and I when we had questions or concerns. I would choose him for anyone in my family or myself in the future. Exceptional surgeon, outstanding manner and outstanding character. What a Doctor should be.

Very glad I chose Dr. Hamstra

Ok, so I had not ever needed surgery prior to this one but Dr. Hamstra made it a very successful one. His staff is professional, attentive and on the ball. He's a no nonsense doctor who explains things clearly and fully. The surgery went well so there was no need to visit me in during the overnight hospital stay so that's the reason for a 3 on the Bedside Manner rating, but I'm sure he would have set a high rating for that as well. Very positive experience and outcome.

Surprise, Surprise!!!

I had emergency surgery and Dr. Hamstra was my surgen. You hear horror stories about how you are just a number but Dr. Hamstra changed that perception quickly. He really cares about your well being. He spends time explaining the options and issues. He gives you time for your questions. He visited me twice in one day. Once at 1pm and another at 9pm following a long day of surgery just to make sure I was ok. He is one of a kind. I highly recommend him.
