About Tricia Mellor

Therapist and Founder of Open Spaces

I was introduced to the horse world when my parents signed me up for riding lessons as a child. Through my childhood and teenage years, riding lessons were my favourite part of the week. I experienced a deep connection to horses and found peace and fulfilment at the barn. I always approached riding as a partnership and treasured my relationships with the horses in my life.

I gained certification as a therapeutic horseback riding instructor through the Canadian Therapeutic Riding Association (CanTRA) in 2002 and volunteered at Sunrise Therapeutic Riding and Learning Centre as I completed my undergraduate degree at the University of Guelph. Sunrise has always held a special place in my heart, and I am honoured to partner with them now to offer EFW services.

I completed my Masters of Social Work at Laurier in 2011. Since 2011, I have worked as a children’s mental health clinician at a community-based agency in Guelph. Through the course of my work, I recognized the need for alternative ways of engaging children, youth and adults in therapy. I knew that horses could help and began my journey to develop Open Spaces.

I have over fifteen years of experience working with children, youth and adults with mental health struggles, learning needs and physical and developmental disabilities.  I bring a client-centred, trauma-informed approach to my work and strive to ensure that clients feel heard, understood and valued.

I currently sit on the CanTRA Board of Directors and chair the CanTRA EFW Committee. I am also a member of the Sunrise Medical Committee.

When I am not working, I enjoy running, biking, reading, cooking and spending time with my family.
