Meet Our Team

Meghan McCann, BA, MS, APRN, FNP-C

Board-Certified Family Nurse Practitioner | Hormone & Functional Medicine Specialist

Meghan McCann is a board-certified Family Nurse Practitioner with advanced post-graduate education and specialized certifications in bioidentical hormone replacement therapy and functional medicine. She earned her nursing degree from Fairfield University and her graduate degree from Georgetown University before pursuing advanced clinical training in hormone optimization and metabolic health.

Frustrated by the limits of conventional care—where patients are often told their labs are "normal" despite persistent symptoms, or simply handed prescriptions that mask root causes—Meghan approaches medicine differently. She treats each patient as a whole person, using comprehensive biomarker diagnostics and evidence-based protocols to help men and women navigate midlife hormonal shifts with confidence, clarity, and long-term vitality.
