When I first started seeing Dr Nonas I had had a severe reaction to a horseback ride. Turned out that I was allergic to about anything in the environment. Today, I seldom have any allergy problems. I credit all this to Dr Nonas for his care, knowledge and skill.

Dr. Nonas must be onze of the most intelligent physicians on the planet. He is factual while intuitive. Within thirty minutes, he reviewed my history, understood my needs, and made recommendations. I recommend him highly. Katherine Georges

Dr. Nonas takes time with patients. He does not work in 15 minute increments as do many doctors. He is the most thorough doctor I have seen. He looks at the entire picture, not just the complaint you have. He is very knowledgable in his field of practice and much more. He does not rush you and...more
