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!
