Dr Tesser is always pleasant to see. He has been my doctor for 15+ years. I see other specialists for migraines and I seem to compare them to his companion and knowledge. No comparison the others fail.

I have been under the care of John Tesser since 2000. I can’t say enough good things about him. I can say he has always been there for me regardless the day.
His expertise in managing arthritis cases is top notch. I trust this man with my life!

Dr. Tesser was so helpful. He helped me find a treatment for my osteoporosis than I can afford and it will be equally effective. This was such a relief to me!

I arrived at the location to see Dr. Tesser and his staff is very good. I wasn’t feeling good at the time little lightheaded and Dr. Tester and his staff took real good care of me. I sure appreciate what they did by helping me get back on my feet, he let me rest for a little bit in the room. I drank some water and went on my way. Very good doctor and helpful staff. Thank you you guys.
