Cognitive Behavioural (CBT) Therapists in Ajax, ON

Victoria Theodoris

Psychotherapist

Therapy is not just about techniques or sessions; it’s about the relationships, and that begins with a conversation. To make this step easier, I offer a free 20-minute consultation. You’ll have the chance to ask questions, share what feels comfortable, and receive a genuine sense of whether working together feels like the right path forward.

Together, we’ll explore what healing looks like for you, at a pace that feels supportive, and work toward feeling more connected, empowered, and well.

Chris Graham

Professional Counsellor, MPCC-Provisional designation with the Canadian Professional Counsellors Association (CPCA).

I work with pilots and men in high-pressure careers who are navigating anxiety, burnout, identity challenges, or major life transitions.

For pilots concerns about career impact, medical implications often create hesitation around seeking support.
