I have over 3 decades of experience working in the fields of mental health and social work. I work with youth, adults, and couples who are struggling with trauma, depression, anxiety, ADHD, autism, relationship issues, and school refusal.
I have spent my career learning and translating theories into practice with individuals, families, couples, and groups. For the last few years, I've gained deeper knowledge working with trauma, anxiety, couples, and the LGBTQIA+ population.

As a Licensed Clinical Social Worker, I believe that prioritizing your mental health is among the most rewarding things you can do. Asking for help is never easy. Congratulations on taking that first step.

No matter what your story is, I am here to walk beside you on your journey to greater well-being.
I'm a Licensed Clinical Social Worker (LCSW) with a background in trauma-informed care, school social work, and a deep passion for supporting mothers, caregivers, and individuals healing from religious trauma. I work with children, teens, and adults navigating anxiety, trauma, emotional regulation, ADHD, and spiritual wounding. My style is warm, grounded, and collaborative, with a focus on helping clients feel safe, seen, and heard. I offer a compassionate, judgment-free space for those processing complex life experiences, including clients who are deconstructing rigid belief systems or navigating the impact of spiritual abuse or exclusion. I welcome clients of all identities and backgrounds, and I deeply value honest connections and authenticity in the healing process.
