Root-Cause Functional Medicine
Healing Advanced Solutions is a functional medicine practice in Jacksonville, FL, led by Catherine Seidle, APRN, whose career began in the ICU. Our approach is integrative medicine at the root cause: we look for why a symptom is there, then build the plan around your biology.
New to the practice? Start here, or take the 1-minute self-assessment.
Standard lab ranges are built from population averages, so a result can be called normal while you still feel off. We read your results against optimal ranges, the values linked with feeling well, and look for the cause instead of just managing the symptoms.
We take the time to understand your symptoms, your history, and your labs as a whole. Then we work through each piece, step by step, to build a plan around you.
Lab flag: none. Outside the functional range.
However you come to us, the path is the same. We understand what is going on, then build a plan that fits you.
In person or over the phone. We help you choose the right service if you are not sure, walk you through what to expect, and answer your questions before you commit to anything.
We run the panels that matter for you, things like thyroid, hormones, and metabolic markers, and read them against optimal ranges, not just what counts as average.
Depending on what we find, that may mean functional medicine, hormone optimization, weight loss, peptides, PRP, or IV and vitamin support. You will always know what each step is for.
Progress is not one and done. You work with the same provider every step of the way, and we adjust as your labs and how you feel change over time.
Come for root-cause functional medicine, or for one focused treatment. Both are medicine, done well.
Most begin with a functional medicine evaluation, then we map the plan to what we find.

The clinician behind every plan
Before becoming a nurse practitioner and moving into functional medicine, Catherine began her career as a registered nurse in a Veterans Affairs hospital ICU, caring for the sickest patients in acute medicine. There she saw the same story again and again: acute crises that began as chronic issues nobody had addressed. She founded Healing Advanced Solutions to catch those problems while they are still preventable, with more time, broader testing, and a plan built around the cause, with the same provider beside you.
Give the body what it needs, and it will do what it was designed to do: heal.
The numbers behind the practice. Real experience, a broad range of conditions, and consistency you can count on.

Functional medicine looks for why a symptom is there, not just how to manage it. We read your labs against optimal ranges instead of the average, consider your full history, and build a plan around the cause. Conventional visits are often short and focused on the symptom. We take more time, test more broadly, and stay with you as your plan changes.
It is for anyone who wants answers instead of another prescription to cover a symptom. We commonly help with thyroid, gut and digestion, weight and metabolism, men's and women's hormones, fatigue, autoimmune concerns, and mood, anxiety, and sleep. Almost any concern can start with the same root-cause approach.
We are a cash-pay practice with transparent, upfront pricing. That lets us give you real provider time instead of rushed, insurance-driven visits. We do not bill insurance or provide diagnosis codes, though we are glad to give you an itemized receipt on request. Care is HSA and FSA eligible.
Your first visit is about 75 minutes with Catherine Seidle, our APRN. We go through your full history from birth to present, review comprehensive labs against optimal ranges, and start building a plan around what we find. You see the same provider at every visit, so nothing gets lost between appointments.
No. We work alongside your primary care provider and any other specialists you see, not instead of them. We focus on root-cause and functional care, and we are glad to coordinate with the rest of your care team.
You do not need to be a functional medicine patient, and no lab work is required. Many IV and vitamin visits are same-day or walk-in. We do ask a few baseline questions first, about your heart, your kidneys, and any allergies, so your treatment is safe for you. The full evaluation is only for root-cause care.
We are at 11555 Central Parkway, Suite 804, Jacksonville, FL 32224. Our hours are Monday 11 a.m. to 4 p.m., Tuesday through Thursday 7 a.m. to 4 p.m., and we are closed Friday through Sunday.
Start with a free consultation, by phone or in person. We help you choose the right service if you are not sure, explain what to expect, and answer your questions before you commit to anything. Book through our contact page or call (904) 373-1661.
