We absolutely miss Dr. Rosenthal as our primary physician. When anyone hears the words wonderful, compassionate and caring, you've hit the nail on the head with Dr. Don! He treated my husband and I for many years and we put our total trust in him and his staff. He is the greatest doctor and friend anyone can have.

My experience with this man was aweful. It's no wonder that so many people dislike doctors. This doctor is the definition of arrogance and an outright disgusting person.

I have called this Doctor 1300 miles from home, and he was available to my attending physician to assist in my care and to ease my fears. He is dedicated and caring.
