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 licensed therapist with a Master’s in Counseling with an emphasis in Child and Family Therapy, and I’m certified in Perinatal Mental Health. I work with children, adolescents, and families, and I also support moms navigating pregnancy, postpartum, and the emotional challenges of early parenthood. I have experience helping with anxiety, emotional regulation, behavioral challenges, and school-related concerns, and I especially enjoy working with children and pre-teens using play and creative approaches.
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.
