I have been a patient for six years. During this time I have found Dr. Posluszny to be warm, personable, and very capable. He does not seem to be harnessed to the "fifteen minutes" many doctors are. He is patient with my questions. He has a fine sense of humor. As I live many hours from his office he accepts email questions from patients which I feel is exceptional. He also has several services in house such as echocardiogram. He has facilitated an amazing improvement in my condition.
