Dr. Katrina Cox, Bsc, ND

Katrina’s story begins 15 years ago as a young, freshly graduated undergraduate deciding what she wanted to do with her life. She knew she wanted to work in healthcare, but she needed to do something unique and with purpose. After acceptance to Medical and Naturopathic College, Katrina decided that becoming a Naturopathic Doctor was her chosen vocation.

After graduating from CCNM, she moved to Bowmanville with her husband, Daniel. Once here, she fell in love with the community and decided to begin private practice. While in private practice, she has done countless hours of continuing education in Canada and abroad. She has been to Germany many times to learn and study from practitioners of integrative medicine and, more specifically, cancer. In 2014 she was invited to attend and present at an international integrative cancer conference.

Dr. Katrina is passionate about helping those struggling with health and surviving chronic illnesses, including cancer, regain control, rebuild confidence and redesign their life. What I’m truly passionate about is helping people thrive and experience more freedom to love living their life again.

Katrina is a member in good standing of the College of Naturopaths of Ontario, the Ontario Association of Naturopathic Doctors and the Canadian Association of Naturopathic Doctors.
