Dr. Tsakonas is wonderful, smart, helpful. I’ll never forget how helpful he was when I needed his expertise. I’m forever grateful. Therefore it was a no brainer to choose him to be my doc.

Great manner and interest in the details of my life. Took his time to listen and offer suggestions to my questions and concerns about my life while scheduling tests to look further into potential causes of mentioned symptoms
