A personalized, investigative approach to integrative medicine. Grounded in science, clarity, and care.
Our Philosophy
Integrative Health Collective was founded on the belief that health is not one-dimensional — and care shouldn’t be either. We exist to support people who want a deeper, more personalized approach to their health, whether they are focused on prevention and longevity or navigating more complex, layered concerns.
Our approach blends conventional diagnostics with functional medicine, longevity science, and thoughtful clinical insight to uncover root causes, restore balance, and support long-term vitality. Care is never formulaic. Every plan is built around the individual.
Meet Dr. Natalie Greenberg, ND
Dr. Natalie Greenberg is a licensed naturopathic doctor in the State of California, who approaches medicine as a partnership, combining rigorous clinical investigation with deep personalization to support prevention, longevity, and complex health needs.
She began her undergraduate studies at Columbia University and later completed her degree in psychology at UC San Diego before earning her naturopathic doctorate from Bastyr University.
Her path into medicine was shaped by personal experience navigating complex illness, which led her to explore and integrate a wide range of natural and functional healing modalities alongside conventional care. This foundation informs her highly personalized, root-cause approach to prevention, longevity, and complex health concerns.
Dr. Greenberg completed advanced clinical training in pediatrics, gynecology, cardiology, autoimmune disease, and mental health, and spent several years practicing at the Center for New Medicine/Cancer Center for Healing under Dr. Leigh Erin Connealy. There, she provided adjunctive integrative care for cancer patients and contributed to research initiatives focused on advanced healing outcomes.
She currently sees patients both in person and virtually. Her clinical focus encompasses hormone balance, chronic illness, detoxification, integrative oncology, and longevity medicine, with care always tailored to the individual.
