I really like Dr. Posner. He understood exactly what I was describing and seemed to really understand that I know myself well and seemed confident in my ability to describe my issues. I feel like some doctors almost try to pokeholes in your story, like you dont know what you're really feeling. I never felt that way with Dr. Posner. He just got it. And gave me a printed out plan for my treatment which I really liked.

My daughter has a chronic illness so we see a lot of doctors and we were both very impressed by Dr. Posner and Lisa. He understood her condition and came up with an excellent action plan. They took their time withus and seemed to really care about my daughter's issues. Dr. Posner was recommended by a friend and I am so thankful for the referral. I would definitely recommend, too.

There is a sense that the office is truly committed to their patients by focusing more time on the patient's wellbeingand less time on the operations of the office. They utilize technology and everyone wins.
