Brenna Kaschor MD, PhD, CCFP

Dr. Brenna Kaschor is a Family Physician with multiple and varied interests and experience. She completed her PhD in Biochemistry at Western University, followed by medical school and family practice residency at the Schulich School of Medicine.

She has received the designation of GP – Focused Practice dermatology and runs the Primary Care Skin Procedures Clinic.

She has also completed additional training in mental health and addiction medicine, working in inpatient and outpatient mental health at London Health Sciences Center (LHSC), and currently manages the Addiction Medicine service at the Victoria Campus of LHSC. She works and advocates for harm reduction and evidence-based treatments for individuals with substance use disorders.

Dr Kaschor is the Founder, Owner and Medical Director of Prisma Health Care Collaborative, a medical clinic in London, Ontario. She is also the founder and one of the directors of GROW: Grounded Roots, Open Wings, a not-for-profit organization whose mission is to prevent and treat adverse childhood experiences (ACEs) and prevent the intergenerational transmission of trauma. She strongly believes that the focus of our health system should be fostering wellness, rather than treating disease. The first 5 years of life are the most important for intellectual, emotional and physical development and investment here provides dividends many times over later on in life.

She has authored many peer-reviewed publications about the effects of early development on disease later in life and her research focuses on how we can identify, assess, prevent and treat toxic stress.

She enjoys cycling, running, and rock climbing with friends, and most importantly spending time with her twins.
