Rachel Griffin, PA-C
Physician Assistant, Certified
Rachel Griffin, PA-C

Rachel was born in North Carolina and has spent the majority of her student and professional career across the state. As a Type 1 diabetic, Rachel has the unique perspective and understanding which fuels her passion to care for patients. She has always been driven by her childhood Endocrinologist, who even from an early age challenged her by asking, “What do you want to do that you are not able to do?” - This changed her perception of a terrible chronic disease to something that she can manage, and still live her life without the disease controlling it. As with her own health and life, she strives to see her patients live their life as uninhibited as possible from their medical conditions. Rachel enjoys being part of the American Academy of Physician Assistants, North Carolina Academy of Physician Assistants and Triangle Area Physician Assistants. In her free time, she enjoys spending time with her husband, daughter, and dog. She also enjoys hobbies such as baking and being active outdoors. Rachel is excited to join the team at Cary Endocrine and Diabetes Center and working together towards the goals the patients and herself set together.

Susan Hyde, PA-C
Physician Assistant, Certified
Susan Hyde, PA-C

Susan Hyde is a board certified physician assistant with a special interest in thyroid disorders (partially due to her own struggles with thyroid disease) as well as women’s health and diabetes. Susan promised her beloved type 1 diabetic Auntie that she would cure diabetes one day, just for her. Sadly she has not managed to cure diabetes yet, but she spends much of her clinical time trying to find new and better ways for diabetics to pursue happiness and healthfulness. She believes health is a partnership between patient and provider, and her role as a clinician is to not only diagnose and treat, but guide and inspire healthy living as well.

When not in clinic, Susan enjoys aerial silks performance, baking macarons, spending time with her husband, and writing fantasy fiction.

Susan is thrilled to be able to continue Cary Endocrine and Diabetes Center’s legacy of excellent patient care!
