    I have seen Dr. Ornstein for a long time. He is kind, courteous, thorough, compassionate and very detail oriented. I never feel rushed under his care, I value any & all advice his gives me at all times. I do miss the fact he is not more locally available and I have to travel much further now.

    I find Dr. Ornstein’s to be very thorough, kind, compassionate (I recently lost my husband) and has many good suggestions for my well being. When I had gone to a dermatologist in Optum that dermatologist dismissed my problem as a topic dermatitis. When I saw Dr. Ornstein I told him and showed him my legs which were filled with these very sore spots. He recommended that I see Dr. Romano and I made an appointment with him. Dr. Romano took a biopsy and it came back as an autoimmune disease. This is why I feel Dr. Ornstein is a very compassionate person and will not send me in the wrong direction. He cares about his patients.
