About Core Function Health

What is Core Function Health?

Core Function Health is a cash-pay practice in Seal Beach, California, focused on hormone therapy, medical weight loss and longevity care. Michele Missakian, PA-C, started the practice and prescribes there. The clinic lists Dr. Carlo Fernandes as its supervising physician, but it does not state his credential. The services listed are Women's Hormone Optimization, Men's TRT, Medical Weight Loss, Longevity & Vitality Optimization, Functional Medicine and Thyroid Optimization. The clinic calls itself California Concierge Care.

The office is at 909 Electric Ave Suite 312C, Seal Beach, CA 90740, and the phone number is 562-248-6546. Much of the care is virtual, but patients must be physically in California at the time of their appointment. The clinic does not list hours. Its articles discuss semaglutide and tirzepatide, but it does not say which weight-loss medications it prescribes. It has a Google rating of 5 from 6 reviews.

What does it cost?

The clinic is cash pay only. In its own words: "we operate strictly on a cash-pay basis." HSA or FSA plans may cover some elements, depending on your plan.

The Medical Weight Loss and Longevity Therapy Consultation is $199 per visit, and that price does not include medication. The Initial BHRT/TRT Consultation is $550 and includes a 60 to 90 minute intake plus a 40-minute follow-up review. The 6-month program is $2,900 and covers continuous medical supervision, repeat hormone panels, check-ins and direct practice message access. Prescriptions and supplements are not included in any of these prices. Specialty lab testing is billed separately when clinically appropriate. The clinic does not publish what medication costs, and it does not state cancellation terms for the 6-month program.

What should you ask before you book?

Ask who writes and signs your prescription, and how Dr. Carlo Fernandes supervises the care. Ask for his credential, since none is stated.

Ask which weight-loss medication would be used, whether it is brand-name or compounded, and what it costs each month. Ask what the lab panels cost and what follow-up visits cost after the first consultation. Ask how to cancel the 6-month program, and ask for the clinic's hours. If you live outside California, ask before booking, since care requires you to be in the state during your appointment.

Who is it a good fit for?

This is a good fit if you are in California, want a cash-pay practice with a PA-C who schedules a 60 to 90 minute first visit, and are ready to pay for medication and labs on top of the clinic's fees. It is a poor fit if you need the medication cost included in the price or need set hours before you commit.
