Dr. Kathleen Mercer was born and raised in St. John’s Newfoundland. After receiving her first Bachelor of Science Degree at Memorial University of Newfoundland, she moved to Asia to teach English and travel.  During this time, Kathleen became interested in Chinese Medicine and decided to return to Canada and further her studies in Naturopathic Medicine. Already having chosen Medicine as a life path, Kathleen felt Naturopathic Medicine encompassed principles of health care that could complement conventional medicine. Some of these principals include: prevention, do no harm, doctor as teacher, stimulate the body’s own vital force to do the healing, healing power of nature, patient as an individual, and finding and treating the root cause of disease.

Kathleen graduated in 2000 from the Canadian College of Naturopathic Medicine after 4 years of Naturopathic Medical Training. She held a successful and busy Practice in Orangeville Ontario for 3 years and then returned to Newfoundland in 2004 to become the first licensed Naturopathic Doctor on the island.

In addition to her training in Naturopathic Medicine, Kathleen is also trained as a Doula and a birth support partner, works with patients going through fertility support, and trained in Cranio- Sacral Therapy. She is also a trained Yoga Teacher and received her qualifications from The Yoga Connection Teacher Training Course in Ontario. She combines all of this additional training with her naturopathic training to provide a unique and well-rounded approach to her practice.

Kathleen’s approach to Naturopathic Medicine includes nutrition, botanical medicine, homeopathy, Chinese medicine, acupuncture, hydrotherapy, and lifestyle counselling. She also does many outreach projects to the public including talks, seminars, and community events.

Kathleen’s practice is a general practice and she sees patients of all ages and circumstances. She is based in St. John’s but is available for virtual appointments.
