Dr. Mark Alan Posner

Excellent doctor, spends as much time as needed (for me 1 1/2 hours and I hear that from others), he reviews any necessary previous paperwork and tests, orders appropriate tests, very knowledgeable and wants to help get an accurate diagnosis.

I have a very complicated health history, so very few doctors understand my health issues much less know how to care for me. Dr. Posner is one of the doctors who you want to have on your team if you have rare and complicated illnesses. I have mast cell activation syndrome, and in many ways he has saved my life. He spends so much time with his patients, and takes time to personally call in follow up, answering any questions in detail. This man is a gem, a true hero.

This is probably the best doctor in any field. He is kind and compassionate and really listens to you. He is not afraid to think outside the box. He is a good human being above all,
