About SHIFT Wellness

What is SHIFT Wellness?

SHIFT Wellness is a private-pay functional medicine clinic at 737 Windy Point Dr. Ste #106, San Marcos, CA 92069. Its main approach starts with bloodwork covering hormones, metabolism, cardiovascular health, thyroid, and nutrients, followed by a review with a licensed provider. The clinic offers four services: Medical Weight Loss, Peptide Therapy, Hormone Optimization, and Functional Lab Testing.

Medical weight loss can include GLP-1 medications when the clinic considers them clinically appropriate. Hormone care can include provider-guided hormone therapy, and peptide therapy is offered under provider guidance when clinically appropriate.

Kelly Nash is listed as the CEO and founder, and she writes that she is not a doctor. The clinic does not name the licensed provider who prescribes, so ask who that is before you book. The office is open Monday through Saturday, 8:00 AM to 6:00 PM, and closed Sunday. Parking is free, right outside the front entrance. The phone number is (760) 215-6264.

What does it cost?

Bloodwork starts at $495. If the bloodwork does not show at least 3 areas the clinic can help optimize, the bloodwork is free. After that, the cost depends on the plan you need, and options are reviewed with you before you start anything.

No prices are published for medical weight loss, hormone therapy, or peptide therapy. It does not say whether medication is included in any price, and no consultation fee is stated. No financing, membership, or cancellation terms are published either. The clinic does not accept insurance, so every cost is paid out of pocket.

What should you ask before you book?

Ask who writes the prescriptions and get that provider's name and license before your first visit. This matters most, because the clinic does not name one.

Ask whether a monthly weight loss fee includes the GLP-1 medication, and what the medication costs on its own. Ask whether it is brand-name or compounded. Ask the same about any hormones or peptides, and who monitors them over time.

Ask what follow-up visits, repeat labs, and refills cost, and whether the $495 covers only the first round of bloodwork. Ask whether telehealth visits are available, since the clinic does not say. Ask how to cancel and whether you can stop partway through a program. Confirm the suite number before you go.

Who is it a good fit for?

This is a good fit if you are ready to pay cash for bloodwork and a provider review before deciding on any medication, and you want testing to come first. It may not suit you if you need insurance billing, a named prescriber before you book, or a written price for ongoing care. In its own words: "We do not start with a drug. We start with your data."
