Holistic Doctor for Thousand Oaks & Conejo Valley Patients
Thousand Oaks and Conejo Valley patients searching for a holistic doctor often find that local UCLA and Cedars-Sinai-affiliated specialists refer functional medicine cases out. Purety Family Medical Clinic in Santa Barbara — about one hour northwest via the 101 — is a specialty naturopathic and functional medicine practice combining root-cause workups with advanced therapies most holistic clinics don't offer (FMT, ozone, IV nutrient therapy, PRP, plasma exchange).

Why Thousand Oaks Patients Choose Purety Clinic
Conejo Valley patients we see are usually in their 40s–60s, dealing with post-antibiotic gut disruption, IBS that has not resolved with PPIs or antispasmodics, perimenopause and male andropause symptoms, autoimmune disease, or persistent fatigue after standard workups came back normal. Many have already cycled through multiple specialists at UCLA Health or Los Robles.
Conejo Valley GI and primary care practices generally refer functional medicine cases out. Purety Clinic is the closest specialty destination and is set up specifically for the patient who has already done the standard medical workup and is looking for a deeper root-cause investigation.

The Naturopathic Difference
Same medical training as an MD in foundational sciences. Different philosophy for what to do with that knowledge.
Conventional Medicine Asks:
- →What drug suppresses this symptom?
- →Are your labs within normal range?
- →Which specialist manages this?
- →What's the standard protocol for this diagnosis?
Naturopathic Medicine Asks:
- Why is this symptom happening in the first place?
- Are your labs optimal — not just normal?
- How are all of your body systems interacting?
- What is the least invasive intervention that addresses the root cause?
