Kandace Mercer, HHP, HP

Founder, Naturally PRYM

Bio:
Kandace Mercer built her career at the bedside before she built Naturally PRYM. A Registered Cardiac Sonographer for thirteen years (RCS, Cardiovascular Credentialing International, 2012–2025), she practiced cardiac sonography across three Florida health systems: UF Health Shands Hospital in Gainesville, Memorial Hospital in Jacksonville, and BayCare Health System in Tampa. Her work spanned echocardiography, vascular ultrasound, and transesophageal echocardiography procedures. That clinical foundation shapes how she approaches wellness today: precise, patient-focused, and grounded in how the body actually works.

Kandace went on to train at The Academy of Practical Homeopathy® and is a Board-Certified Homeopathic Practitioner and Board-Certified Holistic Health Practitioner through the American Association of Natural Wellness Practitioners and its certifying board (AANWP/ANWPB). She founded Naturally PRYM to bring that combination of hospital experience and natural practice to families, integrating practical homeopathy with lifestyle and nutritional guidance. As a mother of four, she brings both professional training and lived experience to every consultation.

Our Approach

Naturally PRYM is a distinct holistic wellness division of PRYM. We focus on personalized education and consultation that honors each person’s goals, preferences, and whole-person wellbeing. Laboratory analysis is provided under the oversight of our Medical Director and licensed, board-certified members of the PRYM clinical team. Wellness consultations are educational, are not medical care, and are not intended to diagnose, treat, cure, or prevent any disease. Naturally PRYM does not provide dietetic or nutrition-counseling services, and its wellness practitioners are not licensed dietitians or nutritionists; any nutrition information shared is general and educational. Clients are encouraged to maintain care with a licensed physician.
