I’m a licensed clinical social worker who specializes in helping children, adolescents, adults, couples, and families navigate anxiety, depression, panic, trauma, PTSD, and other life stressors. With experience in psychiatric crisis care and community outreach, I believe healing starts with feeling safe enough to show up. My goal is to offer real, judgment-free support that meets you where you are and helps you move toward lasting growth.

I feel this work is a vocation driven by humility, love, patience, and integrity. I enjoy developing relationships and assisting people on their way to living life to their fullest potential. I believe the world can change one person at a time through mindful, values-based living. In my free time I enjoy spending time outdoors, with my family and my three little furry friends.

I believe therapy should feel like a space where you can finally exhale. I strive to create an environment that is supportive, honest, and free of judgment; a place where you feel truly seen and emotionally safe. My approach is collaborative and practical. I don’t just help you understand why you feel the way you do; I help you build real tools to navigate it.

I earned my degree from Cal State Fullerton and have extensive experience working in addiction treatment, eating disorder recovery, and women’s issues. Supporting women is especially meaningful to me. I am deeply passionate about helping women navigate challenges related to self-worth, body image, relationships, boundaries, life transitions, and identity. I understand how trauma, societal expectations, and relational dynamics can shape how women see themselves, and I approach this work with both compassion and clarity.

Together, we focus on strengthening mindfulness, emotional regulation, distress tolerance, and communication skills in ways that feel realistic and sustainable. I blend insight-oriented exploration with concrete strategies, because meaningful change happens when insight meets action. My goal is to help you better understand your patterns, feel more confident managing your emotions, and move forward with greater clarity, self-trust, and resilience.
