Our Practice · About

The heart failure had a twenty-year runway. The kidneys did not fail overnight.

The practice that asks why. Healing Advanced Solutions is a functional and integrative medicine practice in Jacksonville, FL, founded and led by Catherine Seidle, APRN, treating root causes with comprehensive testing and visits long enough to find them.

This practice was built around the question most visits never leave time for: why is this happening?

The story

Six years in the ICU changed the question.

Catherine spent six years as a registered nurse in the Medical ICU at the Roudebush VA. Intensive care teaches one lesson over and over: what the end of the road looks like when causes go untreated for decades. The heart failure had a twenty-year runway. The kidneys did not fail overnight. Almost nothing in that unit was sudden.

The move into functional and integrative medicine was deliberate. She saw the gap in care those patients had fallen through, and she became a nurse practitioner to close it: to reach people while their outcomes are still preventable, where the question is not "how do we stabilize this" but "why is this happening at all."

Healing Advanced Solutions is the Jacksonville practice founded from that belief. Long evaluations, comprehensive testing read closely, and plans aimed at what is driving the problem. It is the practice she wished her ICU patients had found twenty years earlier.

The answer to "is a functional medicine practitioner a doctor?" is that some are physicians and some are nurse practitioners, and the letters matter less than training, prescriptive authority, and the time actually spent on your case. All of them live here, in one provider, and she is who you see at every visit.

How care works here.

Test before treating

Plans are built from your labs and history, not from a template. If we would not order it for family, we do not order it for you.

Time with you

The initial evaluation runs 75 minutes. The average primary care visit gives you about eighteen minutes with the provider, and root causes do not surface in eighteen minutes.

Evidence, graded

We grade what we offer by the strength of the evidence behind it, and every treatment page on this site shows where its therapy stands.

Transparent cash-pay

Prices are posted, HSA and FSA work here, and no insurance company writes your protocol.
