Denise T. Donnelly, M.D., knew she wanted to become a doctor from a young age—but not because of a TV show or a science class. It was during a life-changing visit to the family physician when she was just six years old. Her younger brother had recently been diagnosed with autism, and the doctor took the time to explain it not just to her parents, but to her as well.
“I remember walking out of that appointment and thinking, ‘Wow, I feel better,’” she recalls. “That moment stuck with me—how a doctor could help ease anxiety and bring clarity, even to a child. I knew then I wanted to be that kind of doctor.”
Dr. Donnelly earned her Bachelor of Science in Biology, magna cum laude, from Seton Hall University. She then earned her medical degree from Hackensack Meridian School of Medicine.
Though she initially considered pediatrics, Dr. Donnelly discovered her true calling in family medicine during medical school. She was drawn to the continuity of care, the opportunity to support every generation in a family, and the variety of experiences each day brings. “I love that I get to see kids, their parents, their grandparents—all in one day. It keeps things interesting and deeply meaningful.”
Her patients describe her as warm, approachable, and honest. “I’m a people person—I love connecting with patients,” she says. “I talk to them like I’d talk to a friend or family member. No medical jargon, just real conversations about their health and how we can work together to improve it.”
Dr. Donnelly brings a balance of empathy and accountability to her practice. “Sometimes you need a little tough love, but always with compassion. I want my patients to know I care, and I’m rooting for them.”
Outside the office, she enjoys cycling and logging miles on her Peloton. She shares her life with her fiancé, Kyle, and their whippet, Nitro. She also loves spending time with family and winding down with a good book.
