Marianna Guy, Holistic Nurse Practitioner in Greenville SC

Marianna Guy
Family Nurse Practitioner
MSN, APRN, FNP-C

Marianna Guy is a board certified Family Nurse Practitioner with over 15 years of experience in conventional and functional medicine. She is a graduate of the University of Rochester with a Master’s of Science in Nursing, licensed in both South Carolina and New York, and certified by the American Association of Nurse Practitioners (AANP).

Marianna has worked alongside and trained under renowned functional medicine practitioners including Zendi Moldenhauer, MD, Arbor Health Functional Medicine; and Kristi Williams, NP, Well Within Family Practice. She’s also a member of the Institute of Functional Medicine (IFM), where she completed her functional medicine training.

Marianna began her career in healthcare over 15 years ago, caring for patients in a large university hospital setting. While working as a Registered Nurse she realized that the underlying cause of illness was not always addressed by conventional medicine alone. As a result, many patients were not improving in their overall health because their treatment was aimed at symptoms and not underlying root cause conditions. She decided to go beyond conventional medicine and started studying integrative and functional medicine.

Along that journey, Marianna discovered a passion for holistic medicine and pursued a degree as a Family Nurse Practitioner to help her own family, and future patients, thrive rather than just survive. During her clinical rotations, she learned from renowned functional medical practitioners and gained valuable experience in treating the root cause of illness. After working at a wellness clinic and a holistic family practice for several years, Marianna embarked on a journey to open her own holistic private practice so that she can help patients live healthier and happier lives free from debilitating symptoms.

  • We prescribe and sell high quality therapeutic-grade supplements that are available through practitioners by prescription. These supplements are made by companies that we trust, have third-party testing, have higher potency, are easier to digest, and have higher absorption rates, as compared to typical over the counter supplements. Our goal is to establish a treatment plan for you with proper dosing that works. If you chose to purchase another brand somewhere else it becomes more difficult to effectively continue your plan of care. Purchasing supplements online through unverified and unauthorized resellers also means that you may not receive a guaranteed quality product that is effective. Factors such as prolonged storage in warehouses with unregulated temperature, and exposure to extreme temperature during shipping, negatively impact the quality of nutritional supplements.
