Dr. Sarah Waterhouse, ND

Dr. Sarah Waterhouse is a licensed Doctor of Naturopathic Medicine dedicated to providing integrative, evidence-informed care that helps patients feel their best and function optimally. Drawn to naturopathic medicine for its holistic, patient-centered philosophy, Dr. Waterhouse believes true healing comes from understanding and addressing the root causes of illness rather than simply managing symptoms. She works collaboratively with patients to create personalized treatment plans that support long-term wellness, vitality, resilience, and healthy aging.

Today, her practice focuses on helping patients optimize health through individualized, compassionate care that integrates modern diagnostics with natural and functional medicine therapies. Dr. Waterhouse has additional training in integrative aesthetic and rejuvenation therapies and believes that skin health is often deeply connected to hormones, gut health, inflammation, nutrient status, and environmental factors.
