I’m Dr. Erica, a Naturopathic Doctor with a clinical focus on weight management, hormonal and gut health, inflammation, and stress resilience. I also hold a Precision Nutrition Level 1 Certification, which deepened my understanding of behavior, nutrition, and lifestyle change. My approach helps patients uncover and address the underlying factors that influence body composition, energy, metabolism, and overall well-being. I focus on hormone balance, digestion, chronic inflammation, and lifestyle patterns that often make sustainable weight loss challenging.

My journey into naturopathic medicine grew from a lifelong passion for athletics and performance. As a Varsity Women’s Soccer player at the University of Toronto, I learned the value of discipline, resilience, and consistency — qualities that continue to shape my clinical philosophy.

Throughout my athletic career, I was grateful to earn the University of Toronto’s Woman of Influence Award, multiple All-Star and MVP honours, and represent Team Canada at the 2009 FISU World Games in Serbia. I later played professionally in Italy, England, and Iceland before pursuing my studies at the Canadian College of Naturopathic Medicine.

My experiences as both an athlete and a patient reinforced how digestion, hormones, inflammation, recovery, and stress all affect health and performance. In practice, I take a personalized, evidence-informed approach to help patients improve metabolic health, support healthy weight loss, reduce inflammation, and feel more confident in their bodies.

At Georgian Bay Integrative Medicine in Collingwood, I’m grateful to be part of a clinic that values whole-person care — helping patients feel stronger, healthier, and more in control of their long-term well-being.
