I was exceptionally lucky to have found Dr. Avvento. I had a doctor in NYC who had me go through a treatment that has since been removed from the market for various reasons. I am known as the poster child of what could have gone wrong. My Dr in the city was dismissive about side effects. When I met Dr. Avvento and his staff it was life changing. Almost 8 years later they have continued to be not only caring and knowledgeable but they work with me as a team and a family.
