I graduated from Brody School of Medicine at East Carolina in Greenville, NC in 2000.  With plans to do Family Medicine, I opted to do an additional Transitional Year in Baltimore due to personal beliefs that it should be a four year residency.  I completed the three years of Family Medicine residency at UNC Chapel Hill in 2004.


Once working in a group practice, I realized there must be more to medicine as I felt I was doling out pills just for an ill. The list of pills were growing to cover up side effects of other pills.  After my first conference for the American Board of Holistic and Integrative Medicine, I decided to go for board certification which I did successfully in 2013.  For my specialty under the holistic umbrella, I started my functional medicine certification path with the Institute of functional medicine and will complete that in 2016 with plans to sit for the exam in 2017.  Functional medicine searches for the root cause of disease and determines a solution by looking at all the systems in a person using the latest in science.


I also have some training in Ayurveda. This practice from India is four thousand years old and is similar to the eastern version of functional medicine.

Ryan Redd FNP-C


I have been living in North Carolina for the past 2 years and love it here! Prior to moving south, I lived in Ohio where I attended the University of Toledo and earned my Bachelor of Science in Nursing in 2013. I loved bedside nursing but knew I wanted to further my education. In December 2016, I graduated from Simmons College with my Master of Science in Nursing and now a Board Certified Family Nurse Practitioner. Improving the health and lives of others is my passion! 

I enjoy spending my free time with my wife and our two golden retrievers. I am a very active person and enjoy working out, hiking, skiing, golfing, and just about anything sports related. 

My goal as a provider is to put every patient in the driver's seat of their own healthcare. Working together in collaboration and as a team is the key to OUR success!

Sarah O'Neill, MSHS, PA-C


I studied to become a Physician Assistant at the George Washington School of Medicine in Washington, DC finishing in 2001. After practicing in the DC area for a few years, I returned to my native NC to be close to family.  Practicing in Emergency Medicine for eight years and Anesthesiology for nine years provided a solid foundation in medicine. During this journey, it became apparent though that there are so many other modalities to prevent and treat health conditions. Of course I am grateful for acute care medicine, but chronic conditions are not best treated with just another pill! Through some personal health challenges, I learned firsthand the impact of eating patterns & lifestyle habits on improving one's health. I first learned of Functional Medicine in 2013, and it quickly became a passion of mine, as its goal is to treat the root cause of disease, not just mask the symptoms with medication. I started formally studying Functional Medicine in 2017, and became a Certified Provider through the Institute for Functional Medicine at the end of 2019.  I am excited to be a part of Benton Integrative Medicine!

In my spare time, I enjoy yoga, hiking, paddle boarding, reading, traveling & spending time with my two daughters.
