We Are a Network of Queer and Trans-identified Mental Health Professionals Who Serve the 2SLGBTQIA Community
Our team consists of highly skilled, compassionate, radical psychologists, psychotherapists and social workers who have shared expertise in supporting and promoting health and wellness within a 2SLGBTQIA mental health framework.
Our therapeutic approach is grounded in values of feminism, social justice, decolonization, sex and kink-positivity and shapes how our therapists practice trauma-informed and anti- oppressive mental health care.

Acknowledgement
Tkaronto and the surrounding areas that we serve are within the Dish With One Spoon Territory. The Dish With One Spoon is a treaty between the Anishinaabe, Mississaugas and Haudenosaunee that bound them to share the territory and protect the land. Subsequent Indigenous Nations and Peoples, Europeans and all newcomers have been invited into this treaty in the spirit of peace, friendship and respect.
We at Umbrella recognize that the professions of psychology, psychotherapy, and social work have roots in colonial violence. As psychotherapists, we understand that we have a responsibility to continuously work to decolonize the practice of psychotherapy and acknowledge the origins of the various healing practices we utilize.
Our therapists actively engage in regular training that emphasizes professional development, team support, and sharing the current knowledge in 2SLGBTQIA mental health, to ensure the highest level of care for our clients.
