Holistic Doctor for Westlake Village Patients
Westlake Village patients looking for a holistic doctor typically find that local primary care and GI practices refer functional medicine cases out. Purety Family Medical Clinic in Santa Barbara — about one hour from Westlake Village — is a specialty naturopathic and functional medicine practice that combines comprehensive lab testing and root-cause protocols with advanced therapies most holistic clinics don't offer (FMT, ozone, IV nutrient therapy, PRP, plasma exchange).

Why Westlake Village Patients Choose Purety Clinic
Westlake Village patients we see are often high-performance professionals dealing with the gut, hormonal, and stress-related fallout of demanding work and frequent travel — IBS and reflux that hasn't responded to PPIs, perimenopause and male andropause symptoms, autoimmune flares, persistent fatigue, and longevity-focused optimization. Many also come for bioidentical hormone replacement guided by comprehensive testing.
Most Westlake Village area primary care and GI practices do not offer in-house functional medicine workups or interventional therapies. Purety Clinic is the closest specialty destination and is structured for the patient who has exhausted standard medicine and wants a deeper root-cause approach with the option of advanced interventions when appropriate.

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?

"5/20/26 Another victorious EBOO ozone treatment by Dr. Birch and his beloved staff today. My blood is getting stronger with every session so I will keep at it. May perfect health befall you all. ♥️"
"Hands down the most caring doctors and staff I have ever encountered! After a year of my daughter suffering from a variety of symptoms with no real answers we reached out to Dr. Dena Birch and her life was changed. She helped us find the root cause of her symptoms and is now a thriving 17 year old ready to head to college this summer. Without the gentle care of Dr. Dena and Dr. Jonathan this would not be possible. They always go above and beyond and truly feel like family. My family are also patients and it is so refreshing to talk to doctors that truly care in your health and well being."
"Dr. Birch has changed the course of our child’s life. We came to Purety when our son was having extreme gut dysbiosis, which was affecting his development and had gut issues and challenges. About 4 months following the FMT protocol, we tested his gut through a stool test and it was about 90% better. Our son is now thriving! We are so thankful to him foroffering such a life changing treatment. Testing his gut again a year+ later, it showed that the FMT treatment works long term and his gut is still in a great place!"
"5/7/26 UPDATE Another flawless EBOO (ozone dialysis) treatment, my blood is getting stronger and healthier, much more vibrant and brighter in color. Feeling amazing after these sessions. Highly recommended."
"Thank you Dr. Birch for helping me with my chronic knee and ankle injuries!!! You have been a Godsend to many of my patients over the years and now I was able to appreciate and receive your expert care. Everyone should have a Naturopathic Doctor as part of their health care team and I would highly recommend Purity Family Medical Clinic. Don’t hesitate to give them a call. You will definitely be happy with your results."
