Dr. Mark Leonhart is a psychologist completing his supervised practice under the supervision of Dr. Bellefontaine. He works primarily from a Cognitive-Behavioural Therapy (CBT) orientation, including Cognitive Processing Therapy (CPT), but he integrates useful elements of other approaches which focus on aspects of “in the moment” experiences. He provides evidence-based interventions to individual, adult (18+) clients in the areas of mood, anxiety, grief and loss, and adjustment to significant life changes.

Dr. Leonhart is particularly interested in working with individuals with obsessive-compulsive disorder, posttraumatic stress, or operational stress injury.

Dr. Leonhart gained experience providing assessments and psychotherapy to individuals from diverse backgrounds and identities as well as myriad problems with anxiety, mood, obsessive-compulsivity, trauma, and life stressors in a variety of clinic and hospital settings. His completed training in private practices in Montreal, Waterloo, and Ottawa as well as in a campus clinic (University of Waterloo Campus Wellness). He gained experience at inpatient units (McGill University Health Centre General Hospital / OCD Clinic, Homewood Health Centre Traumatic Stress Injury & Concurrent Disorders Program) and outpatient programs (McGill University Health Centre OCD Clinic and CBT Unit).

Dr. Leonhart views clinical work as rooted in the science of how and why people think, feel, and act. With empathy, warmth, and nonjudgment, interventions can be tailored to best meet a person’s needs based on unique experiences, beliefs, and patterns of thinking, feeling, and doing. Collaboratively, he works with clients to help them address underlying reasons for the problematic patterns they experience and develop healthier alternatives. Over time, clients are encouraged to take increasingly active roles as they learn how to interpret and react to situations more adaptively. Clients can become empowered to help themselves. The goal is to help clients be less distressed, feel better, and get back to doing what they want to be doing.
