Background

Dr. O’Neill was always interested in medicine and had a desire to help people. His passion was further stoked when his father passed away due to cancer when he was 13 years old.

During medical school he found a particular aptitude for cardiology and said, “once you find something you’re pretty good at, you fall in love with it, too.” After training in internal medicine and cardiology in New York, he was most recently the director of the cath lab and cardiac critical care at Nassau University Medical Center in East Meadow, N.Y.

Dr. O’Neill’s rural upbringing on his family’s 50-acre dairy farm in upstate New York is one of the factors that attracted him to Beaufort: he and his wife Rita wanted their three children to grow up in a smaller community.
