Leah Geoghegan, AGNP-C, FMCP-M, is a board-certified functional medicine nurse practitioner and the founder of Emergence Health: a telemedicine-first, concierge-style practice serving patients in New York and Connecticut. With a forward-thinking approach to functional care delivery, Leah launched Emergence Health in mid-2020 in response to a growing need for highly personalized, root-cause-focused medicine that could be delivered seamlessly in a virtual setting.

 

Leah has been practicing medicine for 12 years and specializes in the management of complex, chronic health conditions, with particular focus on autoimmunity, women’s health and hormones (including fertility), gastrointestinal (GI) disorders, and environmental exposures such as mold and Lyme disease. Her approach is highly collaborative and deeply attentive - grounded in the belief that meaningful care begins with truly understanding a patient’s lived experience, and translating that into a clear, individualized path toward healing. She believes health is more than just a diagnosis, prescriptions, and jumping into aggressive treatments. Leah considers herself to be a partner and collaborator with her patients, not just a medical provider. 

 

In addition to her clinical work, Leah is deeply committed to advancing the role of nurse practitioners within modern healthcare. She is passionate about supporting NPs in practicing at the full scope of their training and believes they play a central role in the future of both primary care and functional medicine.​

 

Seeking a more comprehensive and proactive approach to care, Leah trained in functional medicine under the mentorship of a leading private practice in New York City before going on to establish Emergence Health.​

 

Earlier in her clinical career, Leah worked in emergency medicine and transplant surgery, where she also trained in disaster response and palliative care, earning her ELNEC (End-of-Life Nursing Education Consortium) certification. These experiences exposed the limitations of conventional care models - where treatment often comes too late, symptoms are addressed in isolation, and patients are left without a clear, cohesive path forward.​

 

Leah earned her Bachelor of Science in Nursing and Global Health from the University of Pennsylvania, where her foundational training shaped her understanding that health is deeply influenced by culture, environment, and the family systems in which patients live. She went on to receive her Master’s degree from New York University’s world-renowned Adult Primary Care and Holistic Care programs. She is certified in functional medicine through the Institute for Functional Medicine (FMCP-M) and has also received training through the Andrew Weil Center for Integrative Medicine. She is a certified medical marijuana prescriber in New York State.

 

Leah lives in Essex, Connecticut on the shoreline with her husband and business partner, John. Outside of her work with patients, she enjoys time in the garden, cooking, and reading thick novels.
