Brenda Tapp Leonard, ND
NATUROPATHIC DOCTOR & CLINIC DIRECTOR
Hello! I’m Dr. Tapp Leonard, ND and I’m so glad you’re here.
Leading the charge in integrative cancer care in Peterborough, I am an Ontario licensed ND and active member of the Oncology Association of Naturopathic Physicians (OncANP).

Cancer changes everything. The treatments, the uncertainty, the fatigue that lingers long after the last appointment, can leave people wondering how to feel like themselves again. But cancer doesn’t get the final say.
​
Much of my work lives at the intersection of conventional cancer care and evidence-informed naturopathic medicine, two worlds that should collaborate more often than they do. I help patients bridge that gap in ways that are thoughtful, practical, and grounded in science.
I started clinical practice 14 years ago, and in that time I’ve seen a lot of medicine at its best… and some parts that clearly needed fixing. I’ve made it something of a professional hobby to examine those rough edges and push for better ways forward. Medicine evolves when people are willing to ask better questions.
​
Sometimes that means being a little early to the conversation. I’ve been prescribing menopause hormone therapy (MHT or HRT or BHRT) since 2016, back when it was still considered “uncool” in many circles. Thankfully, the evidence has caught up, and the conversation is changing. I am confident the same will happen with integrative oncology.
NATUROPATHIC MEDICINE • IV THERAPY • INJECTIONS (B12 + VITAMIN D)
MENOPAUSE HORMONE THERAPY HRT/MHT • ACUPUNCTURE
LAB TESTING • NUTRITION • LASER
​Locally, I’ve worked to pioneer the safe inclusion of evidence-based naturopathic therapies alongside conventional cancer treatment because patients deserve thoughtful integrative care, not an either-or choice.
​
I do a lot because, frankly, there is a lot that still needs doing.
My goal is to leave a meaningful footprint in healthcare here in Peterborough, one that makes it easier for patients to access collaborative, evidence-informed care.
Other Providers
Dr. Shantel Simpson
ND
My interest in maternal and pediatric care grew during my clinical year in school when I was accepted to be part of the competitive pediatrics focus shift.
​
I had the privilege of working with children of all ages from babies to teens and beyond. Seeing the amazing impact that naturopathic medicine had on the health of children and their families has only inspired me more. My love and passion for helping mothers, children and families with their healthcare needs have only grown since starting a family of my own. My husband and I have two young and very active children to keep us on our toes!
I am so grateful for this exciting opportunity and hope to see you soon so we can work together to optimize the health of you and your family!
