Dr Sweeney is always caring, concerned yet not overly intrusive with medical methods. He always asks the patient what you think before going along with care plans. He will be tremendously missed.

He is an exceptional physician. He is whip smart and extremely kind at the same time. I have had the privilege of knowing him for over 17 years. I will miss him terribly when he retires this year. He’s irreplaceable.
