My approach to therapy is trauma-informed, strengths-based, and rooted in connection. I believe in meeting people exactly where they are and creating a safe, supportive space where they feel heard, respected, and empowered to grow at their own pace. I often incorporate mindfulness, emotional awareness, and practical coping strategies to help individuals build resilience and move toward meaningful change. I also bring lived insight into the recovery process, which allows me to show up with empathy, authenticity, and a deep understanding of the work it takes to heal.

I believe healing happens through connection, compassion, and self-discovery, and I feel honored to support individuals as they rediscover their strengths and create a more balanced and fulfilling life.
