Profile
ABOUT ME

I have been practicing internal medicine since 1998. I enjoy the daily challenges of taking care of complex diseases such as diabetes, heart disease, and hypertension (high blood pressure). In addition, I have a strong interest in preventative medicine and preventing diseases before they become a problem. I was born and raised in Pennsylvania. In 2014, I made a decision with my family to move to the Raleigh area to be part of a growing community with a great future. My family and I love spending time together outdoors and look forward to the warmer climate here. I am honored and privileged to be a part of Duke Primary Care.
