    I have had *Dr. Pratt for 20+ years and I've never been sorry.
    Dr Pratt is amazing! He is knowledgable, patient and caring. He spent a considerable amount of time talking with me, asking questions and explaining what was going, even with pictures.
    Excellent experiences.
    Although I usually do not rate a perfect 5 for anything. I feel *Dr. Pratt is a very competent provider. I always repeat his diagnosis and recommendations.
    Dr. Pratt is the finest physician I have ever experienced and he is superb in all areas, medical and social. I am blessed to have as a doctor!
