See what our patients are saying about Marina Cotsilis

This was my very first session with Marina Cotsiis. I was somewhat apprehensive upon our first session. The beginning was a little rocky. No fault of Marina’s. I just have trust issues. However Marina’s knowledge and professionalism allowed me to look forward to my next session with her. I was a little concerned about the age difference (since I am much older than she). Not an issue. Marina’s resume is outstanding.Perhaps she will add a Dr. to it in the future. I was truly impressed.
