What is Center for Advanced Medicine?
Center for Advanced Medicine is an integrative medical practice in Encinitas. It describes itself as an integrated medical center that looks for the root cause of a health problem before it chooses treatment. Its two named prescribers are Dr. Bill Kellas and Dr. Linette Williamson. No credentials are published for either one, so none is given here.
The service list is long. Hormones and Anti-Aging are both on it, alongside Medical, Nutrition, Allergy, Chelation, Detox, Colonic, Acupuncture, Chiropractic and Homeopathy. Weight loss is not a named service, and no GLP-1 or other weight loss medication is named. Peptide therapy is not named either. Its articles treat excess weight as a symptom and describe the eight-day cleanse as an early step in evaluation. In its own words: "We include all the major hormone components including Thyroid, Adrenal, Estrogen, Progesterone, Testosterone and Growth Hormone."
It does not publish a street address on its website, so call (760) 632-9042 for the office location. On Google it is listed as a wellness center, with a 4.2 rating from 25 reviews.
What does it cost?
It does not publish prices. It also does not state a consultation fee, whether it accepts insurance, whether it offers telehealth, or whether any monthly fee includes medication. It does not mention HSA use, financing or a membership term. Supplements are sold separately through its CAM Store, where newsletter subscribers get a 10% discount on most of them. Ask for every fee in writing before your first visit.
What should you ask before you book?
Start with the prescriber. Ask whether Dr. Kellas or Dr. Williamson writes your prescriptions, and what credentials each holds. Ask whether a hormone program is priced with the medication included or billed separately. Ask whether any hormone is brand-name or compounded, and which pharmacy fills it.
Then ask about costs after the first visit. Find out which lab tests are required, how often they are repeated, what each one costs, and whether follow-up visits are included. If the eight-day cleanse is part of your plan, ask what it costs and what it includes. Ask how to cancel, whether there is a contract or minimum term, and whether a late cancellation carries a fee.
If weight management is your goal, ask which medication or program would be used, since none is named. Ask the same about peptide therapy.
Who is it a good fit for?
This is a good fit if you want hormone, allergy and detox services under one roof in Encinitas, and you are ready to pay cash and get answers on the prescriber, the medication and the fees before you book. If you are looking for a named weight loss medication or a peptide program, call first, since neither appears among the services.
