I specialize in helping individuals navigate life transitions, anxiety, depression, narcissism, codependency, people-pleasing, and trauma. My approach is client-centered and collaborative, tailored to your specific needs and goals.
I’m a bilingual Licensed Marriage and Family Therapist who provides therapy in both Spanish and English, from colloquial to professional levels. My work has included supporting individuals facing HIV/AIDS-related challenges, domestic violence, substance use, loneliness, suicidal thoughts, dual diagnosis, sexuality-related concerns, aging-related issues, and the broader impact these experiences can have on families and support systems. Across community, academic, and clinical settings in Mexico and the U.S., I’ve built a strong foundation in helping people navigate both personal suffering and societal distress.
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.
