LeeJoy Ellis, ND, brings more than 30 years of experience at the intersection of clinical wellness, health education, and healthcare marketing. As a naturopathic doctor and integrative health professional, she has built her career on a simple philosophy: uncover the root causes of dysfunction rather than manage symptoms; empower individuals as active participants in their own healing; and bring research-based, disciplined execution to every service level.

With a continued commitment to staying at the forefront of clinical and nutritional science, LeeJoy earned a Bachelor of Science and went on to receive her Doctor of Naturopathy in 2012. She has continued her professional education with a Diploma in Marketing, a Diploma in Integrative and Functional Medicine Coaching, a Certificate in Culinary Medicine, certification as a phlebotomist, and, most recently, a Certificate in Nutritional Strategies for Lifelong Health and Wellness from Duke University School of Medicine.

LeeJoy’s career began with more than a decade in pharmaceutical marketing and advertising across New York, London, and South Africa, where she managed drug-launch and marketing campaigns for major clients including GlaxoSmithKline, Janssen, Bausch + Lomb, and Roche. She also spent two years as a consultant to Pappas Ventures, a global venture-capital firm investing in next-generation life-science companies. Through this work, she developed deep expertise in communicating complex medical information to diverse audiences. In 2016, she transitioned into clinical practice, founding and serving as President of Glow Wellness in Cleveland, Ohio, where she built and scaled a leading IV nutrient and wellness clinic from concept through a successful exit.

Today, LeeJoy channels this full breadth of experience—clinical practice, business ownership, and healthcare branding and marketing—into her work as Chief Wellness Officer at Health Defender.

LeeJoy has three grown children and lives in Palm Beach, Florida, with her husband.
