About Ameri-Cal Weight Clinic

What is Ameri-Cal Weight Clinic?

Ameri-Cal Weight Clinic is a medical weight loss practice with seven locations around the Bay Area, in Antioch, Fairfield, Fremont, Hayward, Pleasanton, Sunnyvale and Walnut Creek. It has been running since 2000, started by Dr. Ronald T. Weiland, and is now overseen by Clinic Director Ron Weiland and Medical Director Dr. William H. Brown, who is the prescriber named for the practice. The weight loss program is built around phentermine, semaglutide and tirzepatide, along with vitamin B12 injections and custom meal plans, and the clinic also offers BHRT for hormone imbalances in men and women. Clinics work on a walk-in basis with no appointments needed, and follow-up visits happen every other week or every fourth week rather than on a fixed schedule.

This listing is for its Pleasanton office at 2324 Santa Rita Rd #1.

What does it cost?

Ameri-Cal does not publish prices for its programs or medications. Payment is due at the time of service, and it accepts credit, debit, cash or check. It does not accept insurance directly, though it says patients can submit an itemized receipt to their own insurer for possible reimbursement. There is no cancellation fee or contract to worry about: in its own words, "our program has no set length, therefore, No long-term contracts are ever required." To get an actual number, you would need to call.

What should you ask before you book?

Ask whether the cost of a visit includes the medication itself, since that is not stated anywhere. Ask whether the semaglutide or tirzepatide prescribed is brand-name or compounded, since neither is specified. Ask what a follow-up visit costs and whether any lab work or blood pressure checks are billed separately, since the program skips the EKGs and blood panels you would get at an annual physical. Ask who will actually see you and sign your prescription at the location you plan to visit, since medication decisions are described as "contingent upon medical clearance by our Medical Director/Physician," and confirm whether that means Dr. Brown personally or another clinician working under him. If timing matters to you, ask about current walk-in hours at that location, since none are listed for any of the seven clinics.

Who is it a good fit for?

This is a good fit if you want an in-person, walk-in weight loss clinic with a long operating history in the Bay Area and no interest in a purely virtual model. It may be less of a fit if you need firm pricing or medication details settled before you drive to a location, since those specifics are not published and have to be asked for by phone.
