What is The G Spa San Francisco?
The G Spa San Francisco is a med spa at 460 Post St in San Francisco, offering body treatments, skin treatments, an acne program, injectables, TMJ relief with Emface, and functional and rehab muscle conditioning including back, core and pelvic floor strengthening. It is run by Dr. Elise Grenier, MD, who has spent decades in primary care and now directs both Downtown Medical Group and this practice. Weight loss is one of its offerings, built around an 8-week program called Functional Freedom Fat Loss™, which pairs a GLP-1 medication, Zepbound or Wegovy, with four Emsculpt Neo sessions, four TruFlex sessions, one TruSculpt treatment, and three FIT3D body scans to track composition changes over the course of the program.
In its own words, the program description states it "is not designed for bargain hunters or quick fixes."
What does it cost?
The Functional Freedom Fat Loss™ program is priced at $5,995 for the full 8 weeks, and that price does not include the medication itself, which is paid separately by the patient. The practice notes the program can run roughly $1,000 to $2,000 a month if financed. Payment is accepted by major credit card, debit card, and cash, and financing is available through PatientFi and Cherry. No insurance billing is mentioned, so this appears to be a cash-pay and financing arrangement rather than one that works with insurance or HSA or FSA directly. A separate membership option elsewhere on the practice's services requires a 6-month commitment, though it is not stated whether that applies to the weight loss program itself.
What should you ask before you book?
Ask what the monthly cost of Zepbound or Wegovy actually runs, since the $5,995 program fee covers the medical supervision, body treatments, and scans, but not the drug. Ask whether labs and the initial medical evaluation are included in that price or billed separately, and what happens if you need extra time beyond the 8 weeks to reach your goals. Confirm that Dr. Grenier is the one reviewing your history and approving the prescription, since that is the only name listed as a prescriber here. If a 6-month membership commitment applies to you, ask what it covers and what the cancellation terms are before you sign anything.
Who is it a good fit for?
This is a good fit for someone who wants a structured, multi-week program with a physician's oversight and some body composition tracking built in, not just a prescription with little else attached. It is probably not the right fit for someone comparing cash per month for medication alone, since the $5,995 price is for the full package of visits and treatments, with the drug cost still to come.
