Written by the company

At CCFM, we have been practicing traditional and functional medicine for decades, and we're working hard to reinvent and optimize how this medicine is delivered to you. For years, our focus has been chronic illness and difficult-to-treat cases, helping patients who had been everywhere else finally find answers and reclaim their health. That work remains at the core of what we do. Today, we also bring that same depth of clinical expertise to people who aren't in crisis but want more from their biology: those managing moderate symptoms, navigating the shifts that come with age, or already performing well and ready to optimize. Whether you're working through something complex or building toward your highest-functioning future self, our goal is the same: help you achieve real, measurable, lasting health. Managing your day-to-day health appointments, medications, nutrition, and lifestyle needs can feel like a full-time job. That's why every patient we interact with is met with understanding and respect in an environment that allows them to share the burdens and the goals of their health journey. We've built an exceptional team of doctors, nurses, nutritionists, coaches, and patient care coordinators who are all focused on one outcome: helping you live your healthiest, longest life.

Excellence

I have been a patient for more than a decade. I deeply value the warmth and expertise these providers share. There is so much information out there and I can bring both core issues and quick questions to each visit. Care is always thoughtful and customized.

I have also especially valued their primary patient-care coordinator, Anita. She is patient, thorough, and skilled at answering all my questions. She brings a kindness and warmth to every online interaction which takes a special person to do.

Finally got real answers!!

Finally got real answers and personal attention/care for my complex chronic illness. CCFM is seriously worth it if you have the means. I spent years bouncing between specialist referrals, getting normal lab work back, and being told "everything looks fine" while feeling miserable. Being so frustrated, I found myself at the California Center for Functional Medicine (CCFM). I came to CCFM struggling with severe chronic fatigue, dysautonomia/POTS symptoms, and unresolved gut issues that standard GI doctors completely missed. From my first meeting with Dr. Schweig, the level of medical rigor here was completely different. Before my initial consultation, my care team reviewed a detailed timeline of my health history and previous lab work...omg! they actually came into the visit prepared. Their diagnostic approach is incredible. Instead of just prescribing a Band-Aid medication, Dr. Schweig ordered advanced specialty labs (like comprehensive stool testing and organic acids tests) to map out the root causes. During our 60-minute Case Review, he explained the data visually and built a truly personalized protocol combining targeted diet changes, antimicrobial herbs, and useful lifestyle adjustments. What you need to know about the model/cost: CCFM operates as a direct cash-pay/concierge practice (around $2,500 for the onboarding phase, plus a monthly membership). You get what you pay for. Having unlimited access to my health coach and nutritionist between doctor visits kept me accountable and made the treatment plan actually doable. Within six months on their protocol, my brain fog cleared up, my digestion normalized, and I got my energy back. CCFM gave me my life back when the conventional system gave up. I highly recommend Dr. Schweig and the whole CCFM team.

The California Center for Functional…

The California Center for Functional Medicine (CCFM) promises a better approach to healthcare, but they don't deliver. It feels like a business that is trying to scale, but they are doing that at the expense of the patient experience. The clinicians themselves are competent and caring, but the system they have developed is frustrating.

1) They rely on a subscription model, which is very opaque and hard to navigate. The website doesn't mention this, but after 6 months you can't update your subscription level. Mind you, there is no dashboard to see how many "minutes" you have used.

2) You cannot contact your clinicians directly, all messages go through the staff (which are often slow and/or unresponsive) so you end up playing games of telephone even with simple yes/no questions.

3) I'm not sure if the staff is spread to thin, but the support is awful. Messages are not returned for weeks or even at all and the communication itself is often very rushed and incomplete. You get a lot of super long messages because they are using templates and form responses. I don't need everything just for me, but it is just an example of them shifting burden to patients to make things easier and more "efficient".

I had hoped that CCFM would be a more holistic model for healthcare where they would be partners for me. If that was the case the expense would be worth it. As it is, you get a worse experience at a higher price.
