Are you feeling a shift in your mood or energy? Struggling with relationships or feeling overwhelmed by life's challenges? It's okay to feel this way—sometimes, our emotions, thoughts, and experiences can become too much to handle alone. In our sessions, we’ll work together to explore what’s going on at a pace that feels right for you. My goal is to create a supportive and nonjudgmental space where you can find comfort and strength as you work through these difficulties.
With over a decade of experience as a registered social worker, I specialize in working with individuals, couples, and families. I am passionate about helping individuals build healthier, more fulfilling relationships, including the relationships we nurture with ourselves. My approach is grounded in narrative, attachment-based, and trauma-informed therapies.
Finding the right therapist is like any relationship - it's about connection. I invite you to reach out and see if we are the right therapeutic fit.
