Priscilla Harrison, RDH
Dental Hygienist & Healthcare Advocate
Priscilla Harrison’s journey into healthcare was born from personal tragedy and deep transformation. At just 25, she lost her mother after a courageous 17-year battle with cancer—an experience that profoundly shaped her perspective and ignited a lifelong commitment to health and wellness. Motivated by this personal loss, Priscilla immersed herself in learning about prevention, wellness, and the science behind lasting health. She chose a path in dental hygiene, recognizing the critical connection between oral health and overall well-being. With years of clinical experience, she has become a passionate advocate for education, early intervention, and proactive care. Today, Priscilla serves not only as a dental professional but also as a wellness leader—continually seeking innovative, evidence-based solutions that help individuals live healthier, more vibrant lives. Her mission with Zestal is clear: to help others take control of their wellness journey, elevate awareness around prevention, and empower communities to thrive. Through her work with the Zestal Healthcare Professionals Council, Priscilla brings both heart and expertise—bridging science, compassion, and purpose to support holistic health for all.

AnneJeanette, PA
Physician Assistant
With nearly 35 years of experience as a clinical Physician Assistant specializing in Cardiothoracic and colorectal surgery, I have dedicated my career to helping patients through some of the most critical and complex phases of their health journey. My passion for medicine was always rooted in the desire to make a difference- whether in the operating room or at the bedside. Now, after decades of surgical practice, I'm channeling that same passion into preventative care and wellness. I've seen firsthand how chronic disease often begins years before symptoms arise, and I'm committed to helping people make informed, sustainable lifestyle choices that can prevent illness before it starts. My goal is to empower individuals to live healthier, more vibrant lives through education, early intervention, and a proactive approach to health.
