Population Focus

My counseling style is warm and empathetic. I consider it a privilege to be allowed to know your story and bring any tools I can to help you on your journey. I believe in being an authentic person in therapy sessions, as such my style is interactive and engaging. I believe in challenging the thoughts and patterns which can keep us stuck but always doing so in a respectful and inquisitive manner. My approach is eclectic; I primarily draw from a Client-Centered approach, with a combination of Cognitive Behavioral Therapy (CBT) and Dialectical Behavioral Therapy (DBT). I do not limit your experience with me to these approaches exclusively, if there is a tool I believe would be of merit from other therapy styles I Iove to incorporate them. I really do believe everyone I meet has strengths and I like to amplify them in our work together. As a bilingual Spanish and English-speaking therapist, I have a passion for helping multicultural families.

I am so grateful to be allowed to help empower you and live the life you strive for.
