Tustin Longevity Center
Verified listingAbout Tustin Longevity Center
Tustin Longevity Center is an integrative and functional medicine practice at 825 Parkcenter Drive, Suite 100 Santa Ana, CA 92705. Here is the headline for anyone shopping cash-pay: this practice bills insurance. Its own insurance page displays Aetna, Anthem, Cigna, United Healthcare, Blue Shield and Medicare. The only prices published anywhere belong to a small content membership, not to care.
## Does it take insurance?
Yes, and it says so directly: "Here are just some of the insurance we accept. To find out if your insurance is accepted, give our office a call!" The home page goes further, stating that the practice accepts most commercial PPO plans, Medicare Advantage PPO plans, traditional Medicare and Tricare, with the note that a primary plan must be in-network. Self-pay is offered for HMO and out-of-network patients, and the home page states explicitly that the practice cannot work with MediCal patients.
That makes this an insurance-billing medical practice that also takes self-pay, rather than a cash-pay clinic. If you found this listing while comparing self-pay prices, adjust your expectations.
## What does care cost?
No consultation fee, visit fee, program price or lab price appears anywhere on the site. For an insurance-billing practice that is unsurprising, since your cost depends on your plan. CareCredit is named as a financing option, with the instruction to "Please call our office to learn which services accept CareCredit".
## What is TLC+, and is it the price of care?
No, and this is the most misreadable thing on the site. TLC+ is a membership published at $9.99/month or $349.99/year, available only to current and approved patients. What it buys is free shipping on all orders, access to content not available to the public, and the chance to take part in fireside chats with the doctors. It has no contract and is cancellable anytime. It does not buy visits, labs or treatment, and neither figure is the price of being a patient here.
## What is offered, and by whom?
Services are listed as Integrative Functional Medicine, Women's Health, Men's Health, Weight Loss & Nutritional Counseling, Bioidentical Hormone Replacement, Lab Testing, IV Therapy and a supplement shop, TLC Nutrishop.
Five providers are named: Rita Ellithorpe, MD; Cyndee Mitchell, MD; Leanna Gonzales, MPAP, PA-C; Esther Lamb, MPAS, PA-C; and Noah Alt, ND. That is an unusually clear roster for this category, where the prescriber often goes unnamed. Hours are Monday to Friday, 8am to 5pm.
## What is not published?
No medication is named anywhere. There is no GLP-1 brand, no semaglutide, no testosterone product. Weight work is described only as "Weight Loss & Nutritional Counseling" and hormone work only as "Bioidentical Hormone Replacement", so you cannot tell what would actually be prescribed. No telehealth statement exists; the about page refers to in-person hours but never states a virtual option. No service area is claimed. No founding year and no years-of-experience figure appears. There is no eligibility statement or step-by-step process for becoming a patient.
Two structural notes. Despite the name, no Tustin address appears anywhere on the site; every page publishes the Santa Ana address, so the name is historical rather than locational. And the site is a Shopify storefront wrapped around a medical practice, with a large supplement catalogue whose listings did not render prices for us. All of this was checked on 22 September 2026.
