Dr. Hammarstedt is one of the best doctors that I have ever worked with. He is quite competent and very conscientious. My hand surgery went smoothly and after that I was able to recover from a severe dog bite.

Dr. Hammarstedt is awesome. He is always attentive and caring. I got shots today and he talked to me about surgery. I will make that decision soon.

The doc was on time and the office efficient. That is all the positive I have to say. I have a finger that is not working right, severely jammed in Nov. The doc doesn’t believe there is anything they can do to fix it but still orders an MRI. How much out of pocket is that going to cost me? And then to what end?
I already have little faith in what Dr.’s can do. Have I seen some miracles; Yes. But honestly I feel our medical system is like going to a witch doctor. I just want my finger to be flat and straight and work again. Why bother with the mri
I even asked about taking a mallet to it. He did advise against that but I need help. Feeling bummed.
