Dr. Tessar is a gem. I worship the grounds he walks on. He is a great physician and a very humble person. Which makes me drive 50 mins to see him

So thankful to Dr Tesser over the last 23 years. He always has my back and making sure to help me control my RA. Very attentive and knowledgeable on what may or may not help to control the symptoms. Best doctor in my opinion.
