Meet the Team
Sarah Southerton
Founder, Integrative Health Practitioner (IHP2) & Functional Medicine Health Coach
Driven by my own transformative healing journey, I founded Healing Masters to guide others towards optimal wellbeing. With accreditations from the esteemed Functional Medicine Coaching Academy and Integrative Health Practitioner Institute, with additional training in functional blood chemistry analysis, epigenetic, and bioresonance, I specialize in navigating complex health challenges that conventional medicine hasn’t been able to help, using natural holistic approaches and functional lab testing. I bring broad knowledge and deep expertise in connecting the dots, interpreting lab results, personalizing health protocols, and educating on a variety of wellness topics, including mindset, gut health, parasite cleansing, detox, and natural treatments for all types of health conditions, including Lyme with co-infections, mold illness, and chronic fatigue. It's all about getting and staying well, naturally, and I'm here to show you how.
