Dr A. Kirk Haun has been my eye doctor for many years. I lost my left eye to cancer when I was a baby so my vision is of the upmost importance. Dr Hauns father, Dr Louis Haun was in the same practice as Dr David McCroskey, who found the cancer and saved my life. I saw Dr Louis Haun until he retired.Dr Haun is professional, caring, dedicated to his patients care. He always answers all my questions and works tirelessly to get any concerns with my vision resolved.I have been seen by eye doctors and surgeons all over the country butI will never trust my vision to anyone else.I see Dr Haun at the Maryville office. Everyone in the practice is amazing to work with. They are friendly and prompt to return calls.Only the highest regards and recommendations for this office!
