OUR TEAM

Joanie Jackson, FNP-C, is a board-certified Family Nurse Practitioner and the founder of Freedom Integrative Wellness. With almost 20 years of clinical experience spanning cardiac/progressive care, neurosurgical intensive care, primary care, and functional medicine, Joanie is passionate about helping patients navigate complex chronic illness through an evidence-informed, personalized approach.

After witnessing the limitations of conventional medicine alone, Joanie pursued advanced training in functional and integrative medicine to better serve patients seeking answers beyond symptom management. Today, her primary clinical focus is Integrative Oncology, where she partners with individuals before, during, and after cancer treatment to optimize health, improve quality of life, reduce treatment-related side effects, and support long-term outcomes.

Joanie has completed advanced Integrative Oncology training through the Metabolic Terrain Institute of Health, studying under internationally recognized integrative oncologist Dr. Nasha Winters. She has also earned certification in Mistletoe Therapy through the PAAM (Practitioners of Applied and Advanced Medicine) and completed advanced Ozone Therapy certification under renowned ozone medicine pioneer Dr. Frank Shallenberger. These specialized trainings allow her to thoughtfully integrate evidence-informed metabolic therapies, ozone therapy, and mistletoe protocols into individualized cancer care plans alongside conventional treatment.

Her clinical approach integrates nutrition, metabolic therapies, ozone therapy, mistletoe, targeted supplementation, hormone optimization, detoxification strategies, nervous system regulation, hyperthermia, and other emerging adjunctive therapies alongside conventional oncology care. Joanie believes patients deserve a collaborative healthcare team that addresses the whole person—not simply the diagnosis.

As a lifelong learner, she continues advanced education in the rapidly evolving field of metabolic and integrative oncology to bring innovative, research-informed therapies to her patients while maintaining the highest standards of compassionate, patient-centered care.

A Fort Mill native, Joanie is married to her high school sweetheart, Stephen, and together they have two children. Outside the clinic, she enjoys traveling, relaxing at the beach, spending time with family, and cheering on the South Carolina Gamecocks.

The Six Stepping Stones to Wellness

Diagram titled "The Six Stepping Stones to Wellness" with six sections: 1) Detoxification, 2) Hormone Balancing, 3) Stress Management, 4) Whole Nutrition, 5) Exercise Programs, 6) Nervous System Health.

  • Everyday toxins burden the body, slowing essential functions. Our personalized detox programs use physician-grade supplements and whole-food nutrition to reset and prepare your body for deeper healing—without crash diets or extreme cleanses.

  • Hormones regulate metabolism, mood, and energy. Through comprehensive testing and customized care, we identify imbalances and provide targeted nutrition, supplementation, and lifestyle support to restore harmony.

  • Chronic stress disrupts digestion, immunity, and mental clarity. Our programs include adrenal function testing, supplementation, and lifestyle coaching to help your body recover and build long-term resilience.

  • We take the guesswork out of eating well with personalized food sensitivity testing, science-backed dietary plans, and hands-on guidance so you can confidently nourish your body for vitality and disease prevention.

  • Fitness—not weight—is the key to longevity. We provide custom movement plans, yoga classes, and sun saunas to help you build strength, flexibility, and endurance in a way that fits your lifestyle.

  • A balanced nervous system enhances digestion, immunity, and mobility. We offer neurological assessments, chiropractic care, and targeted interventions to restore full-body function.

    Wellness is a journey, not a quick fix. By integrating all six steps, you’ll create lasting health and vitality—and we’ll be with you every step of the way.
