Record provenance
Details are drawn from this provider's public record in the CMS National Provider Identifier registry, which CMS last updated on April 12, 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.
Endocrinologists specialize in hormone-related conditions — diabetes, thyroid disease, and metabolic disorders. They were prescribing GLP-1 medications for type 2 diabetes years before the drugs became known for weight loss, so they tend to have deep experience with dosing, side effects, and how these medications interact with other conditions.
Call (713) 486-1200 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.
