A Practice Built on Answers, Not Quick Fixes
Our Mission at Delaware Functional Medicine and Longevity is to deliver physician-led care that identifies and treats the root causes of illness while promoting long-term wellness.
Guided by the expertise of board-certified physician Dr. David M. Creech, we combine advanced diagnostics, functional medicine strategies, and innovative recovery tools to help patients in Wilmington build healthier futures.

Meet Dr. David M. Creech
Dr. Creech is a board-certified physician with extensive training in both traditional and functional medicine. He earned his Doctor of Medicine from Drexel University College of Medicine in Philadelphia, where he developed a strong foundation in clinical practice. After medical school, he completed his residency and years of patient care across clinical and surgical settings.
While experienced in conventional medicine, Dr. Creech saw its limitations in treating chronic conditions. Too often, patients were given symptom-relief prescriptions without answers about why they were sick. This led him to functional medicine, where he could combine advanced diagnostics, lifestyle interventions, and innovative therapies to help patients truly heal.
Today, Dr. Creech blends his traditional medical expertise with a functional medicine approach. His patients benefit from both thorough diagnostics and innovative therapies such as biohacking tools, advanced lab testing, and personalized recovery programs.
