love Dr. Grudziak

December 28, 2016

everyone there was so wonderful and caring especially to my son.

December 14, 2016

I thought Dr. Jan was awesome! He was very thorough and seemed exceptionally knowledgeable in this area. We feel very comfortable with the next steps in treating our daughter.

December 08, 2016

Dr. G is the best!!!!!!!!!!!!! I always recommend him when my associates ask about bone doctors for the kids

December 08, 2016

Very good visit. Only issue was that our appointment was 3:15pm but we did not see the doctor until after 4pm.

December 08, 2016

Dr Gruziak is a very good doctor. We have had to use him a number of times due to injuries. We appreciate the care he has provider to our child. He has a calmness about him that helps our son a lot. He relates well to athletic teenage boys and makes them understand what is necessary for their care. Also, I would like to point out that his administrative assistant Gretchen is top notch as well. She goes above and beyond to make sure that his patients are taken care of through dealing with all the red tape of insurance to what you need to do for surgeries to scheduling follow ups. I can't say enough good things about Dr Gruziak and Gretchen. They really try to ensure smooth experience for both the parents and the patient.

December 06, 2016

Dr. G was very personable and had a great sense of humor. He was able to put my daughter at ease.

December 01, 2016

Dr. Grudziak is an extremely good surgeon and caring person who takes his time and is willing to listen and talk about my care and my options. I would highly recommend him.

December 01, 2016

This was a follow up appointment for a problem my child was diagnosed with a year ago. The doctor made it seem like he had no idea we had been to see him before for the same condition. He wanted me to fill out paperwork as if my child was a new patient, even though the MA tried to tell him my child was not a new patient.

I am always amazed at how well this office stays on schedule and their prompt attention to patients.
