    I have had him for my doctor for many years and LOVE his attention and willingness to listen. I am very sad to know he is retiring. But it is well deserved and I wish him nothing but the best.

    He has been my primary care physician for 35 years. He is an excellent Doctor, with great respect for his patients. My only regret is he is retiring and I know it will be hard to find another Doctor to fill his shoes for me as a patient. He was superb.
