Patient Reviews
Apr 28, 2025
I have been seeing Dr. Mary Koumas for over 25 years and I don't want to ever change doctors! She is very respectful, caring, and will listen to all your needs all while explaining to help you understand. She spends a long time with her patients and never feel rushed. and is very knowledgeable and good at what she does! I've also had Dr John Koumas and her PA, and their bedside manner is equally good.
