Vibrance Health

Functional Medicine Doctor & Lifestyle Medicine located in Westlake Village, CA

Welcome to Vibrance Health

Darren FX Clair, MD, has been practicing medicine in the Los Angeles area for over 30 years and has helped thousands of patients improve and maintain their overall health and vitality. Dr. Clair is a functional medicine physician treating patients at Vibrance Health, which is located in Westlake Village, California. 

He believes that the first step to assisting his patients in attaining optimal health is to spend an adequate amount of time with each patient and obtain a comprehensive review of their medical history in order to assess their current level of health, lifestyle, and to learn of any symptoms they may be experiencing. Although there are certainly instances where prescription medication is necessary, Dr. Clair’s primary objective is to look for ways to work with a natural healing ability of a patient's body to develop and maintain ultimate good health.

Dr. Clair believes that it is not enough to rely strictly on lab test results as a way to diagnose a patient’s health issues. Lab tests frequently do not accurately reflect how you, as a patient, are feeling or functioning. Most lab tests are a comparison to others and do not take into account the fact that each patient is unique. Even if a test result may be within the “normal” range, it may not be optimal. Dr. Clair actively listens to his patients about how they are feeling and, if required, uses state-of-the-art non-invasive testing to determine the best course of action for the patient.

Dr. Clair is a graduate of Columbia University’s College of Physicians and Surgeons and completed his postgraduate work at UCLA Hospital. He is a Board Certified anesthesiologist, and in 2003, he opened Vibrance Medical Group in order to help people to use their body’s natural curative powers to heal their ailments and stay healthy. In 2017, Dr. Clair became one of only 300 doctors to have earned the title of Certified Lifestyle Physician with the American Board of Lifestyle Medicine.

Dr. Clair was a co-investigator on an FDA-approved investigation of human growth hormone as an anti-aging agent and has published an article on growth hormone replacement in the prestigious Journal of Medicine. He has frequently appeared on TV news segments and The Doctors Show, discussing a wide range of various health-related subjects.

In 2018, Vibrance opened a meditation and yoga studio to complement the medical practice and offers stress-relieving programs to the Westlake Village community. Dr. Clair believes that yoga and meditation can be of great benefit to you on your journey to optimal health and wellness.

Additionally, Dr. Clair and the team at Vibrance Medical Group offer aesthetic services like Botox® and dermal fillers that can effectively diminish many visible signs of aging, like fine lines and wrinkles. 

Our mission and goal is to help each and every one of our patients feel their very best at any and every age.



Dr. Clair developed the “Wheel of Health” to represent many of the various components of optimal health, including: heart health, stress management, hormone balancing, weight loss, sleep, nutrition, vitamin deficiency, detox programs, and rejuvenation therapies.

By considering all of these factors and focusing on each patient’s individual short-term and long-term health goals, Dr. Clair creates a proactive plan to meet those individualized goals.
