Dr. Prionas was the best! He read my history carefully and went over my situation, giving me additional understanding of my surgery and diagnosis. I especially appreciate how thorough and clear he was when going over the different scenarios and possible treatments going forward. I felt that he really cared about his patients and was extremely knowledgeable and experienced, communicating his expertise in an organized and caring fashion. Thank you!

Dr. Prionas is the perfect doctor. He's clinical and informative, but also incredibly personable and clearly listens to the patient. I learned new things about my entire cancer journey that I'd never heard from either my surgical or medical oncologist. His bedside manner is the best there could be, and he quickly perceives how to work with each patient. As I have heard others say, "I wish he was my doctor for everything". My immediate thought after the video meeting today was, "Where have you been for the last 6 months"? I wished I'd had a doctor patient relationship with him from the beginning.
