Dr. Alison M. Sullivan

I was born in northern Virginia and spent my childhood growing up in close proximity to Washington, D.C. I then attended Virginia Tech, where I obtained a bachelor’s degree in exercise physiology but – more importantly – I met my beautiful wife, Karen, to whom I have been married since 2002. Prior to attending medical school, I worked in a number of different health-related fields, including rehabilitation and business administration for a transplant center. Shortly after marriage, my wife and I left Virginia for the sunny state of Florida, where I attended medical school at Nova Southeastern University. While there, I received my Doctor of Osteopathic Medicine and developed a distinct interest in women’s healthcare. My first delivery as a medical student was my oldest daughter. I completed my residency training at Carolinas Medical Center in Charlotte, NC – a residency training program that heavily emphasized outstanding patient care and advanced surgical training. My family continued to grow during my residency as my second daughter was born. I feel it is a privilege to care for women and their families throughout their life. I believe that OB/GYN provides special opportunities to closely care for young people as they build a family, advance through adulthood and make the transition into menopause. It is what defines the field as truly unique and a great specialty. I am providing care in both obstetrics and gynecology with a special interest in complex minimally invasive gynecological surgery and general obstetric care. My interests away from work include spending time with my family, attending church and enjoying all of the outdoor activities that East Tennessee offers. My family and I are thrilled to be here servicing the needs of Johnson City and the surrounding communities.

For as long as I can remember, I have always wanted to care for those in need. My childhood experience in helping care for a terminally ill grandparent inspired me to make an impact in healthcare. This early motivation propelled me through the many steps of training, including graduating from Mercer University School of Medicine as a top national scholar and completing residency at Carolinas Medical Center in Charlotte, NC, with top surgical honors. I received my OB/GYN certification in 2009. Over this time, I have continually devoted myself to providing knowledgeable, compassionate and cutting-edge care. As a husband, father and member of the local Christian community, I understand how the different facets of life affect our health. My ambition is to recognize not only the physical but also the emotional, psychological and spiritual needs of women from all walks of life. In obstetrics, my interests include fertility evaluation, prenatal counseling and low- and high-risk pregnancies. As for gynecology, my expertise includes minimally invasive surgeries such as robotics, single incision laparoscopy, as well as vaginal prolapse repair.
