Lisa Diffley, RD, IL | Dietitian

About Lisa Diffley

"With over 20 years of experience as a Dietitian and Diabetes Educator—and more than 50 years of personally living with Type 1 diabetes—I bring a unique depth of empathy, insight, and resilience to my practice. My personal journey with diabetes has shaped not only my clinical expertise but also the compassionate, patient-centered care I provide to those navigating both Type 1 and Type 2 diabetes. I have extensive experience with Insulin Pump Therapy and am dedicated to empowering individuals to manage their diabetes with confidence and clarity. Outside of my professional life, I find joy and balance through my deep love of Scottish Terriers. Whether competing in agility and conformation events, hiking, or simply enjoying quiet time on the couch, my dogs—and my supportive husband—play an essential role in my well-being. This active, fulfilling lifestyle underscores the holistic approach I bring to my work: one that honors the connection between body, mind, and community. Resilient, knowledgeable, and driven by genuine passion, I strive to inspire and support others in overcoming challenges and embracing wellness."
