Patient reviews for Dr. Mark Posner
I have been seeing Dr. Posner for 5 years. He doesn't rush through visits, asks follow up questions and makes many recommendations. He will always take the time to look for samples or coupons for my medication, which I truly appreciate.
Dr. Posner was a great listener and made me feel very comfortable. He explained everything clearly and answered any questions I had. While I don’t have a need to see him again because allergies/asthma aren’t my issue I would certainly recommend him to others and will use him again if my condition changes.
Office staff was friendly and efficient. Dr. Posner's medical assistant was thorough and knowledgable. Dr. Posner was wonderful - thorough, respectful, and was great with questions. Super bedside manner.

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.
