Cheryl Champagne, M.Ed., RP

I work with individuals who are dealing with the effects of abuse, loss, and life transitions: toxic, unhealthy or abusive relationships; sexual violence; bullying or harassment; death of a family member or friend; break-ups; coming out or transitioning; and in general feeling lost and needing to find the way forward. I am a Registered Psychotherapist with 25 years experience working with diverse clients, including individuals who are racialized, LGBTQ+, or have a disability. I identify myself as a white cis-gender female lesbian. I have extensive experience helping clients navigate and be successful in a post-secondary environment, whether they are dealing with trauma, mental health, or the challenges of being the first generation in their family to attend post-secondary.

I bring a trauma and violence informed perspective, along with many tools and approaches such as narrative training, mindfulness meditation, attachment, cognitive behavioral therapy and more. In therapy, we work together to set goals and make a plan for what you would like to work on. In addition to gaining more understanding of your strengths, coping skills, values and priorities in life, we identify and work on skills such as setting boundaries, decision making, stress management, and creating healthy relationships and community. The past need not define you— you can take what you learned from it, and work towards the life you want for yourself.

I love to travel and have lived overseas in Zimbabwe and Bangladesh. I have two very affectionate cats and enjoy balcony gardening, riding my bicycle around town, camping and hiking. I also have a regular meditation and yoga practice. My clients tell me I bring a calm and compassionate presence to our work together. I look forward to meeting you and helping you wherever you are along your journey.
