We don't manage numbers.
We find what's wrong.
Conventional medicine is built to name a disease and match it to a drug. Functional medicine asks a different question: why is this happening — and what will it take to fix it at the source?
A real first visit — not a rushed appointment
Your first visit is a full 45–60 minutes. We review your complete health history, talk through every symptom — including the ones other doctors waved off — and identify which functional tests will give us the clearest picture of what's driving how you feel.
- Complete exam & full health-history review
- One-on-one consultation with Dr. Parker
- The right functional testing for your symptoms
- A personalized healing roadmap
What working with us looks like
Listen to your whole story
Your first visit is 45–60 minutes. We review your full health history and every symptom — including the ones other doctors waved off.
Test, don't guess
Comprehensive functional labs: full thyroid panel, cortisol & hormones, food sensitivities, GI-barrier and microbiome markers, key nutrients, and antibody testing for chronic infections.
Find the root cause
We connect the dots across thyroid, gut, adrenal, and nutritional systems to find what's actually driving how you feel.
Build a realistic plan
A personalized roadmap — nutrition, targeted supplementation, and supportive therapies — designed around your life, not a one-size protocol.
The web of physiological dysfunction
Your symptoms rarely live in one system. Fatigue can come from the thyroid. The thyroid can be driven by the gut. The gut can be inflamed by food and infections. We map those connections instead of treating each symptom in isolation.
- Whole-body, root-cause framework
- Whole-food nutrition & targeted supplementation
- Supportive healing therapies as part of a clinical plan
- No rushed visits, no dismissals
Frequently asked questions
What kind of practice are you?
We're a root-cause, holistic office focused on nutrition and the underlying drivers of your health. Rather than treating symptoms in isolation, we look at the whole body — thyroid, gut, hormones, and nutrition — to help you feel your best naturally, and we're glad to work alongside the rest of your care team.
Are Drs. Parker medical doctors or endocrinologists?
Drs. John and Alexa Parker are chiropractic physicians (D.C.) with 600+ post-graduate hours in functional neurology and functional nutrition, in practice in Tampa since 2004. We are not endocrinologists and do not have them on staff — we offer a functional, nutrition-based approach to the same conditions.
What kinds of testing do you use?
Comprehensive functional blood analysis, cortisol and hormone testing, autoimmune and food-sensitivity testing, and gut-barrier/microbiome assessment. We also use cutting-edge labs that look for acute and chronic infections, along with applied kinesiology testing — chosen based on your symptoms and history.
How long until I feel better?
It varies. Functional medicine works with your body, so it takes time — but many patients notice meaningful change within the first several weeks. We're honest about what's realistic for your situation.
