Most of us aren't born knowing how to navigate relationships, understand our emotions, or process trauma. Many things influence how we react and behave, but that doesn't mean we can't grow. My goal is to help you build confidence through discovering your self-worth and practicing self-compassion. My priority is creating a safe, judgment-free environment where you feel comfortable. I show up as my authentic self to build trust with you. I'm an empathetic listener and communicate in a calm, gentle, respectful way. My job isn't to tell you what to do, but to help you process and explore topics to build self-awareness and confidence.

I am a Licensed Clinical Social Worker with 10 years of social work experience and 5 years of experience as a psychotherapist. My experience ranges from treating children ages 5 and older to treating geriatric individuals aged 70+. I am a bilingual, Latina therapist and I conduct therapy in both English and Spanish. I have worked in a variety of settings including community mental health and private practice treating a range of mental health issues such as depression, anxiety, OCD, PTSD, co-occurring disorders, and more. Much of my work has been focused on working with the Latino community in Southern California as well as disadvantaged communities of color.
