Record provenance
Details are drawn from this provider's public record in the CMS National Provider Identifier registry, which CMS last updated on October 1, 2023. Registry specialty indicates the care a provider is registered to deliver — it is not confirmation that this practice currently prescribes GLP‑1 medications. Call to confirm current services, availability, and pricing.
Family and internal medicine providers manage weight as part of whole-person care. A primary-care-based GLP-1 program can be a good fit if you want your weight, labs, blood pressure, and other medications managed in one place — and it often simplifies insurance coverage.
Call (844) 547-4343 and ask these questions before booking:
About compounded medications: A compounded drug is prepared by a state-licensed compounding pharmacy. Compounded drugs are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, and they are not the same as FDA-approved generic drugs. Ask any practice which it dispenses and which pharmacy prepares it.
