Our physicians specialize in obstetrics and gynecology, which includes the examination, diagnosis, prevention and treatment of women’s health problems. In addition to standard specialty care in obstetrics and gynecology, we offer evaluation and management of infertility, gynecologic urology, menopausal management, endoscopic and laser surgery, medically or surgically complicated obstetrics, mammography, and ultrasonography.

Craig Aren Myers, M.D., F.A.C.O.G.

What Dr. Myers enjoys most about practicing obstetrics and gynecology is the relationships he develops with his patients. He feels that medical care is a partnership and that patients should be involved in all aspects. His interests include general obstetrical care, pelvic pain, sexual dysfunction, laparoscopic surgery and menopausal care. Good health begins with preventive medical care and healthy living. Laughing a lot also helps. It is important for the patient to feel comfortable and confident with her physician, and Dr. Myers works hard at fostering that relationship.

As a full time physician, mother, and wife, Dr. Cottam understands all the demands and challenges women of today encounter. Her practice has grown since her arrival in Knoxville in 1999, in large part, due to her being able to relate to a wide variety of patient concerns and problems. Her practice includes all aspects of general Obstetrical and Gynecologic care, including counseling, annual exam, problem visits and surgeries.

During the past seventeen years that he has been in practice, he has been successful in developing a large obstetrical practice. He has a unique ability to make patients and their families “feel right at home.” It is obvious to all that he enjoys being a physician.
