Derek Cassidy, MSW, RSW


Registered Social Worker

Derek is a registered social worker with the Ontario College of Social Workers and Social Service Workers and a member of the Canadian Association of Social Workers. They graduated with a Master of Social Work from the University of Toronto and a Bachelor of Social Work from Carleton University. Derek is a white, genderqueer settler who has been working with 2SLGBTQ+ communities for over seven years in community health and mental health settings.

Derek believes that tuning into our stories and emotions can provide us with insight that nurtures growth and healing. They offer a supportive and collaborative space to be heard, work through difficult emotions, and explore new possibilities and perspectives. Derek also helps connect individual experiences with mental health and wellness to larger systems and structures like heteronormativity, cisnormativity, settler-colonialism, patriarchy, capitalism, etc. They approach this work with curiosity, thoughtfulness, and compassion.

Derek has experience working with people who may be looking to gain a deeper understanding of their gender or sexual identity, their relationships, or their substance use (including PnP). They also support people who may be struggling with stress, depression, and anxiety. Derek draws upon several therapeutic modalities depending on each person’s needs, focus, and goals for therapy including narrative, emotion-focused therapy, cognitive behavioural therapy, and solution-focused approaches. Their work is trauma-informed and rooted in anti-racist and anti-oppressive frameworks and harm reduction principles.
