I like that he takes time to explain things in a way that I understand. I like that he spends the time with his patients to go over lab results and answer questions and discuss next steps at length, instead of it being a 15 minute visit like a lot of providers do.

Dr. Jaar is what I would describe as a ""physician's physician!"" If I were to give an example of who I consider the perfect prototype of a physician, it would be Dr. Jaar! He is extremely knowledgeable and very warm and personable. I have never felt rushed during our visits and he takes care to provide me with very thorough explanations and medical advice in a way that I can readily understand. In short, he is the best doctor ever!
