Reclaim Your Vitality. Discover the Root Cause.
Personalized functional medicine led by John Brennan, PA. Move beyond symptom management with precision testing and whole-person healing.
You're not alone
Many feel stuck in a cycle of symptoms
If these sound familiar, a deeper approach may be the answer.
Persistent Fatigue
Sleep and coffee no longer restore your energy. You feel exhausted despite "normal" bloodwork.
Brain Fog & Focus Issues
Difficulty concentrating, memory lapses, and that sense of not feeling like yourself.
Symptom Management Only
Multiple prescriptions and diets that mask issues but never resolve the underlying drivers.
A different path is possible, one rooted in understanding your unique biology.
Meet John Brennan, PA-C
With over 10 years of clinical experience as a Physician Assistant in orthopedics and formal training in functional medicine, John founded Infinite Natural Health after his own transformative healing journey.
After a life-changing injury requiring five surgeries and years of debilitating headaches, fatigue, and brain fog, John discovered the power of addressing root causes. Functional medicine allowed him to eliminate all prescriptions and reclaim his vitality.
Today, he brings that same personalized, data-driven approach to help others break free from symptom management and build lasting wellness, body, mind, and spirit.
John blends medical expertise with life coaching to design care that fits you.

Frequently asked
Seeking Truth? Start Here.
What is the free discovery visit?
It is a no-cost, no-obligation conversation where John reviews your symptoms, history, and prior testing, gives you an honest perspective on what may be contributing, and helps you decide whether the program is the right next step. There is no pressure to enroll.
Is this medical care or coaching?
Infinite Natural Health LLC provides health consulting and educational services. While John Brennan is a Certified Physician Assistant, this program is consulting and educational in nature and is not a substitute for professional medical advice, diagnosis, or treatment from your primary care physician.
I have already tried diets, supplements, and protocols. How is this different?
Those approaches typically focus on symptom management. John's method uses precision lab testing to identify what may be driving your symptoms, then builds a personalized plan around those findings rather than generic, one-size-fits-all advice.
What is included in the program?
An integrative initial consultation, precision lab testing, and ongoing support with regular 1:1 check-ins, progress tracking, personalized protocols, and direct access messaging. Exact format is reviewed on your discovery visit.
How much does the program cost?
Program investment is discussed during the discovery visit, after we understand your situation and whether the program is the right fit. Payment options are available.
What happens after I submit the application?
After submitting the short application, you will be invited to book your free discovery visit. The visit covers your symptoms, history, prior testing, and goals, and concludes with an honest perspective on whether the program is the right next step for you.
Will I have to follow an extreme diet?
No. Recommendations are personalized based on your lab results and individual response. The goal is sustainable, root-cause change rather than long-term, restrictive elimination.
Do I need a referral or prior labs to start?
No referral is needed. Existing labs can be reviewed during the initial consultation. The program includes functional testing for those who do not already have recent results.
