My website

My ideal clients come to therapy because they’re tired of feeling like anxiety, BPD, depression, or difficulty setting boundaries is taking over their lives. They’re ready for something to change—and I’m here to help you take back control. Together, we’ll create an individualized, collaborative treatment plan that reflects your goals, needs, and strengths. Using evidence-based interventions, I’ll help you better understand what’s keeping you stuck, develop practical tools to manage what you’re experiencing, and build the confidence to move forward.

I specialize in supporting teens and young adults as they navigate anxiety, depression, relationship concerns, self-esteem, and life transitions. If you’re new to therapy and nervous about the process, I offer walk-and-talk sessions as well as colouring and crafting sessions as alternative ways to connect and feel more comfortable during therapy.

If you’re curious about whether we might be a good fit, I invite you to reach out for a free consultation so we can briefly connect and see if working together feels right.
