Dear Dr. McCain,
Thank you so much for seeing me so quickly. Your office staff is wonderful. They took the extra steps to make sure my tests were done immediately. When a patient has a problem there is nothing nicer than people who really take the time to care. Thanks to you…

Dear Dr. McCain,
Over my professional career in the health care field, I have had the pleasure of talking with and getting to know hundreds of physicians personally. Occasionally, one stands above all others. You, Dr. McCain are such a man. There are no words to truly express my gratitude for your outstanding care, professionalism and obvious sincere concern for your patients physical and mental well-being. My diagnosis was devastating but I knew the instant I first met you that I was in excellent hands, those of not just a world-class surgeon but and sincere physician as well. Although your professional accolades and accomplishments speak for themselves, I felt the need to add a small note of heartfelt gratitude of my own. Additionally, I would be remiss if I did not say an added "Thank You" to your excellent staff. Their attention to detail and to my, and others in the waiting room, was second to none. They too helped make a most serious and sometimes scary time in my life a little less stressful. Sincerely, William M.
