Who We Are

We are a team of healthcare professionals who believe health is both a personal responsibility and a personal choice. We further believe that optimal health can only be attained when the body functions properly. As such, we practice from a functional medicine perspective. Functional medicine serves as a “bridge” between standard pharmaceutical-based medicine and holistic therapies, focusing on restoring the body’s ability to function in the manner it was designed.

What We Offer

We offer both in-person and virtual appointments. Our preference is to see new patients in person to get to know you on a direct level, but we recognize this is not possible in all cases. We offer remote/telehealth appointments for those who are unable to leave home or live a significant distance away from our Northeast Florida office.

Our Philosophy

The functional medicine model is an individualized, patient-centered, science-based approach that empowers patients and practitioners to work together to address the underlying causes of disease and promote optimal wellness. It requires a detailed understanding of each patient’s genetic, biochemical, and lifestyle factors and leverages that data to direct personalized treatment plans that lead to improved patient outcomes.

Lynn-Kettell Slifer, APRN, MSN, RN-BSN

Lynn Kettell-Slifer is a Family Nurse Practitioner licensed in several states, including her “home base” of sunny Florida. Her educational background includes multiple graduate and undergraduate science, technology, and Nursing degrees, completion of the requirements for Autonomous Practice in the state of Florida, Advanced Practice training in Functional Medicine, Certification in The Bredesen Protocol for Cognitive Decline, Reiki training, and countless Continuing Education credits covering a multitude of areas within both allopathic and Functional medicine. Her focus areas include tick-borne illness, Mold/mycotoxin illness, autoimmune conditions, hormones, GI, and cognitive decline.

Lynn’s career background includes years in research and development, directing R&D and Venture Development for the NJ Commission on Science and Technology, consulting on health related issues, volunteering and working in underserved clinics/medical missions, and opening/managing a series of primary care clinics.

She has written numerous health-related articles and presented at multiple organizations and venues.

Lynn holds memberships in multiple organizations including The American Association of Nurse Practitioners, The Institute for Functional Medicine, The Association for Advancement of Restorative Medicine, and Realm of Caring.

Lynn credits her strong faith in Jesus for continued guidance, and in her restorative time enjoys biking/hiking, travel, time with family, and working with her rescue dogs.

In 2016, Lynn decided to open her own practice to enable her to address the shortcomings of insurance- based medicine. Her goal was to return to the true roots of health care, spend the time needed to understand and treat each patient as an individual, and use integrative modalities of treatment known through evidence-based research to improve symptoms and restore health. Health Partners LLC was launched, and continues to thrive and grow. Lynn is passionate about treating each patient as an individual- this approach gives her the ability to truly understand and treat the often overlooked causes of declines in health.

Common Questions About Our Practice

“...The goal of Functional Medicine is to not just treat symptoms, as in the standard acute care model followed by most health care providers today. Rather, Functional Medicine seeks to go ‘upstream’ from where the symptoms began and address the root causes of the symptoms. By addressing the root cause of the symptoms and correcting ‘dysfunction’ in the body, all patients become healthier and a large number find partial to full relief of symptoms.”

Lynn was incredibly thorough and helpful. I have been through many doctors in the last 10 years and Lynn has been the only person to not only accurately diagnose my disorder, but also effectively treat it. Two thumbs up!

Shellie Ferguson

Thoughtful, caring, professional and knowledgeable. Has met far beyond my expectations. I gathered information in only my first visit that I can use for a lifetime.

Kathy Waller

Health Partners LLC has been a FANTASTIC FIND! I was sick for so long and they knew exactly what to do to make me feel like myself again (and even better honestly.) Lynn was able to order the appropriate diagnostics, refer me for the imaging I needed, and then get me on the correct regimen of medication, supplements, diet, and more to help me get better. She actually took me OFF things...

Ganesh Place

Every experience that I have had with Health Partners has been positive. They go "above and beyond" to help me with my health concerns, finding answers to issues that other medical professionals could not provide. I am very grateful to have found them. I highly recommend their services.

Rachel Johnston

Going to Health Partners has been such a blessing for my family and I. Lynn helped me identify toxins as being the root cause of extreme fatigue and an irregular heart beat that I struggled with for over two years. She helped me evaluate stress, nutrition, environmental toxins, and many other things to get me back on my feet. Lynn truly cares about her patients! I always recommend Health Partners to anyone...

Concetta Cenac

I have had the best experience with Lynn and her staff since I came home from Mexico with a parasite. Because of a lifetime of infections and antibiotic use, I have dealt with digestive issues my entire adult life. I feel better now, after only 2 months, than I have in many years. At 69 years of age, I am more energy than most 30-year-olds. I am looking forward to a long-health restoring relationship with Lynn!

Vincent Rifino

Very professional and helpful!

Brian Wideman

Lynn is absolutely fantastic. I stopped going to my primary care physician after seeing Lynn. She doesn’t want to load you up on pills, she wants to help figure out the root cause to your ailments and fix them in a way that is better for your body. I have also lost 40lbs in 6 months since seeing Lynn.

Darcy Angers

Out of the blue, my normally healthy husband was diagnosed with two debilitating autoimmune disorders. His health declined rapidly to the point that he was so weak and in so much pain that he could barely function. He was referred to a rheumatologist who immediately prescribed injections of Humira, a biologic with a long list of extreme side effects. The doctor couldn’t explain to...

Stephanie Wideman

Lynn has helped me to manage stress, eliminate foods in my diet that were leading to weight gain and inflammation (and possible allergies), and teach me WHAT to eat. I have lost 30 lbs. under her care. She is knowledgeable and she listens to me when other doctors I have seen gave me a 10 minute appointment. She spent 2 hours with me on my first visit. Highly recommend!

Karen Owen

Lynn Kettell-Slifer really cares. Making my body work the way it was meant to through proper diet, nutrition, and using pharmaceuticals only when absolutely necessary is an approach that worked for me. The extensive blood testing went over and above what a typical doc would order and gave lots more information about my health to treat my underlying problem.
