    "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!"

    "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."

    "After four rounds of Vancomycin and two of Fidaxomicin, I had lost 18 lbs and could barely leave the house. My GI doctor told me FMT was my last option and referred me to Dr. Birch. He walked me through everything, answered every nervous question I had, and the procedure itself took less than an hour. Within 48 hours the diarrhea stopped. Three months later I'm still in complete remission. It genuinely saved my life."

    FMT — Recurrent C. difficile

    "A prolonged antibiotic course left my gut a mess — bloating, loose stools, brain fog, anxiety. My gastroenterologist had no answers. A friend sent me Dr. Birch's page and I booked a telehealth consult. He was thorough, evidence-based, and clearly knew the literature better than anyone I'd seen. The FMT protocol restored me in ways I didn't think were possible. I'm sleeping better, thinking more clearly, and my digestion is normal for the first time in two years."

    FMT — Post-antibiotic Gut Dysbiosis

    "I had been flaring on and off for three years despite two different biologics. My husband found Purety after researching FMT for colitis. Dr. Birch did a detailed intake and set realistic expectations — he was honest that it wasn't a guaranteed cure but that the evidence was promising. I'm now nine months post-procedure with no flares, and my last colonoscopy showed significant mucosal healing. My GI doctor was genuinely surprised."

    FMT — Ulcerative Colitis

    "I was told by two orthopedists that I needed a total knee replacement at 54. I wasn't ready to do that. Dr. Birch did a thorough ultrasound evaluation and recommended a series of PRP injections. After three sessions spread over four months I'm hiking again, playing pickleball twice a week, and have no more daily pain. I wish I'd found this years ago."

    PRP — Knee Osteoarthritis

    "Partial rotator cuff tear after a fall — my surgeon wanted to operate immediately. Dr. Birch's ultrasound-guided approach was precise and the recovery was so much easier than surgery would have been. Six months out, my MRI shows significant improvement and I'm back to full range of motion. The entire team at Purety made every visit feel comfortable."

    Stem Cell Therapy — Shoulder Tear

    "I was skeptical about PRP for hair loss but Dr. Birch explained the mechanism clearly and showed me the research. After four sessions I have noticeable regrowth in my crown and temples. It's not magic — you need to be patient and consistent — but the results are real. He also caught a thyroid issue on my labs that my GP had been missing for years, which was a huge bonus."

    PRP — Hair Restoration

    "Seven years of Lyme treatment, countless antibiotics, herbal protocols, and I still couldn't function normally. A Lyme specialist I trust recommended EBO2 at Purety. The staff are professional, the environment is calm and clean, and Dr. Birch monitors every session personally. After eight sessions I have more energy than I've had in a decade. It hasn't cured everything but it's the most dramatic improvement I've experienced."

    EBO2 / EBOO — Chronic Lyme Disease

    "Fibromyalgia and chronic fatigue for six years. I'd tried everything. EBO2 was the most aggressive treatment I'd attempted and I was nervous. Dr. Birch walked me through exactly what would happen. The sessions are peaceful — you just lie there reading while the machine does its work. After the third session I started sleeping through the night for the first time in years. The fatigue has lifted substantially."

    EBO2 / EBOO — Autoimmune Fatigue

    "Mold illness from a water-damaged home left me with neurological symptoms, joint pain, and severe fatigue. I did ten rounds of Multipass ozone therapy alongside Dr. Birch's detox protocol. The combination was transformative. My inflammation markers are down, my cognitive function has returned, and I finally feel like myself again. Dr. Birch approaches each patient as an individual — he doesn't give everyone the same protocol."

    Multipass Ozone — Mold Illness

    "My conventional OB ran labs, said everything was 'normal,' and offered me antidepressants. Dr. Dena ran a comprehensive hormonal panel and found several imbalances that had been missed. Her approach is methodical and unhurried. She explains everything in plain language, never talks down to you, and actually follows up between appointments. My energy, mood, and cycle have all normalized. I send every woman I know here."

    Women's Health — Hormonal Imbalance

    "I had been symptomatic for years — hair loss, irregular periods, weight gain, exhaustion — but my TSH was always 'in range' so my doctors dismissed me. Dr. Dena ordered a full thyroid panel including T3, reverse T3, and antibodies, and identified Hashimoto's. Her treatment plan addressed root causes rather than just suppressing numbers. Eighteen months later I feel completely different. She's exceptional."

    Rachel S.

    Women's Health — Thyroid / PCOS

    "Hot flashes, insomnia, brain fog, mood swings — all dismissed as 'normal aging' by my GP. Dr. Dena took the time to actually investigate. Her bioidentical hormone approach was thoughtful and carefully monitored. Within three months I was sleeping again and my quality of life dramatically improved. The fact that she also practices integrative medicine means she treats everything together rather than in silos."

    Nicole B.

    Women's Health — Perimenopause

    "Our five-year-old had severe eczema from infancy and we were cycling through steroid creams with no lasting relief. Dr. Dena identified underlying gut dysbiosis and food sensitivities we hadn't connected. Her protocol — gentle, natural, and very well explained — cleared his skin almost completely within four months. She's so wonderful with kids. He asks when he gets to see 'the nice doctor' again."

    Pediatrics — Eczema & Gut Health

    "Our daughter had seven ear infections in one year. The pediatrician recommended ear tubes immediately. We wanted a second opinion and came to Dr. Dena. She identified dietary triggers and a vitamin D deficiency, suggested some structural work with a pediatric chiropractor, and recommended some targeted supplements. It's been fourteen months and not a single ear infection. We avoided surgery entirely."

    Pediatrics — Recurrent Ear Infections

    "Eighteen months of long COVID with debilitating fatigue, cognitive impairment, and post-exertional malaise. I had done extensive research and found the German data on TPE promising. Dr. Birch was one of the only physicians in the country offering it in a clinical setting. His protocol is rigorous. Five sessions in, my cognitive function returned to about 80% of normal — better than I'd hoped after so long. I'm continuing treatment and remain optimistic."

    Therapeutic Plasma Exchange — Long COVID

    "Years of autoimmune symptoms bouncing between rheumatologists who kept adding medications without improvement. Dr. Birch took a completely different approach — rather than layering more immunosuppression, he looked at root causes. TPE alongside his functional medicine protocol has reduced my inflammatory markers by over 60% in six months. For the first time I feel like someone is actually treating me, not just managing numbers."
