What is Ameri-Cal Weight Clinic?
Ameri-Cal Weight Clinic is a medical weight loss practice with clinics in Antioch, Fairfield, Fremont, Hayward, Pleasanton, Sunnyvale and Walnut Creek, all in California. It was started in 2000 by Dr. Ronald T. Weiland. Dr. William H. Brown is the named Medical Director and prescriber. No credentials are published for him. The main phone line is +1 (888) 688-4389.
Its services are GLP-1 treatments with semaglutide and tirzepatide, appetite suppressant pills with phentermine, vitamin B12 injections, bio-identical hormone replacement (BHRT) and custom meal plans. The weight loss program combines nutrition, medication and support. It also lists cosmetic injectables such as BOTOX and JUVÉDERM, which are separate from its weight loss and hormone services. Walk-ins are welcome. Google reviews give it 5 stars from 12 reviews.
This listing is for its Antioch office at 3720 Sunset Ln Ste c.
What does it cost?
Ameri-Cal does not publish prices. You are asked to call for pricing details. The consultation is described as free. Payment is due at the time of service, by credit, debit, cash or check.
The initial visit includes a physician consultation covering medical history, body composition, weight and blood pressure. It also includes four weeks of appetite suppressants or GLP-1 prescriptions, subject to medical clearance by the Medical Director. Whether medication is included in any price is not stated.
Ameri-Cal does not accept insurance as payment. Many patients are reimbursed by their insurer after submitting an itemized receipt, so you would pay in full first.
The weight loss program has no set length. In its own words: "Our program has no set length, therefore, No long-term contracts are ever required." Cancellation terms and any fees are not described.
What should you ask before you book?
Ask who signs your prescription, and whether Dr. Brown or another clinician prescribes at the office you visit. Ask whether the GLP-1 and phentermine prescriptions are brand-name or compounded.
Ask whether any price includes medication. The program description mentions up-charges for dosage increases, so ask how much a dose change costs.
Ask about lab work. The program description says the clinic does not run an EKG or blood workup, and that these come from your annual physical. The hormone therapy material says simple blood tests help decide what you need. Ask which tests your treatment requires and what they cost if drawn at the clinic.
Ask how follow-up works. The program description says there are no mandatory weekly meetings or set follow-up schedules, while the About page describes visits every other week or every fourth week. Ask which applies to you and what each follow-up visit costs.
Ask whether any part of your care can be done by video. Phone and email support is mentioned, but video visits are not described.
Ask how to cancel and whether a fee applies. Ask which office will handle your care, since existing patients can come to any location.
Who is it a good fit for?
This is a good fit if you want in-person medical weight loss care at a walk-in clinic, you are ready to pay cash and file your own insurance reimbursement, and you want clear answers on prescribing, labs and cancellation before you pay. It is a weaker fit if you need a published price before you call, since none is listed.
