I am a Psychiatric Mental Health Nurse Practitioner (PMHNP) who provides compassionate, evidence-based care for adults. My approach is clinical, trauma-informed, and whole-person; I look beyond symptoms alone and consider the many parts of life that shape mental health. I believe care should feel collaborative, supportive, and not overwhelming. My goal is to help you feel understood while creating a treatment plan that fits your life, values, and goals. Whether you are seeking medication management, in-office IV or IM ketamine treatment, or support through a difficult season, I want you to feel safe, respected, and empowered.

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.

If you’re carrying trauma, anxiety, or depression, you’ve found a warm and steady place to start. I’m a seasoned Licensed Clinical Social Worker, and mindfulness has been a deeply important part of my own life and my work for nearly 30 years. Over the years, I’ve completed intensive meditation training in India, Nepal, Sri Lanka, and the United States, experiences that have profoundly shaped how I understand healing, presence, and the connection between mind and body. I’d be honored to bring all of that to you.

I believe people carry far more strength, clarity, and resilience than they often realize. My role is to help you understand the emotional patterns and internal narratives that shape your experience, so you can move through life with greater freedom and self‐trust. I’m engaged, attuned, and honest in the room — offering reflection, insight, and steady collaboration as we explore what’s happening beneath the surface. We work at a pace that feels grounded for you, creating space for real change to germinate.
