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.

I'm Roz Hedayatian, a Licensed Marriage and Family Therapist in Los Angeles. I work with adults who are navigating relational pain, anxiety, and life transitions. My clients tend to be self-aware, curious about themselves, and ready to go deeper than managing symptoms. If you've ever felt like you understand your patterns but can't seem to change them, that's exactly the kind of thing we'd explore together.

You’re capable and use to managing a lot, but lately life feels overwhelming.
