About me

Hola/Hello! I'm a Licensed Professional Counselor (LPC) based in Houston TX. I received my MS from University of Houston Clear Lake, and I have been practicing for 6+ years. I work with adolescents and young adults who have experienced trauma and need help transitioning into adult life. I also have experience and enjoy helping women in different life challenging situations, from domestic violence to career burn-out. Besides my degree in counseling, I hold a Ph.D. in Hispanic Studies and I'm a former academic with extensive training and expertise in cultural identity issues due to migration. I am knowledgeable in feminist theory and gender issues as well as a proud LGBTQ+ ally. I'm fully bilingual (Spanish and English), Trauma Focused-Cognitive Behavioral Therapy certified and EMDR trained.

Get to know me

In our first session together, here's what you can expect

In our first session together, we'll start with brief introductions, and I will focus on learning about you and specific needs and challenges you're facing. I will meet you where you are and prepare a tailored treatment plan for us to work through in follow-up sessions. En nuestra primera sesión comenzaremos por conocernos, enfocando en cuáles son tus necesidades y los desafíos a los que te enfrentas o en aquello que quieres trabajar a través de la terapia. Conjuntamente prepararemos un plan diseñado específicamente para tí y que será la guía para las sesiones siguientes, con la flexibilidad necesaria para que alcances tus metas.

The biggest strengths that I bring into our sessions

I'm empathetic and compassionate with extensive experience in helping people, particularly minorities, overcome life-challenges, find hope and a path towards feeling fulfillment in their lives. Soy una persona empática y sensible a las necesidades de otros, con mucha experiencia ayudando como mentora y terapeuta. Traigo un bagaje de experiencias multiculturales y diversas que juntamente con mi formación me preparan para ayudar a otros a superar desafíos de la vida y encontrar esperanza, abriendo camino hacia la realización personal.

My treatment methods

Trauma-Focused CBT

I'm TF-CBT certified and have four+ years of experience with this treatment method, working mainly with adolescents.

EMDR

I have been trained in EMDR and in the process of being certified. This treatment method is very effective with clients who have experienced trauma and have difficulty processing through traditional talk-therapy based methods.

Mindfulness-Based Therapy

I have been trained and ususally integrate Mindfulness-Based therapy and DBT to my practice, particularly when assessment proves this approach could be benefitial for the client.

Compassion Focused

It is an integral part of my philosophy to approach my clients with compassion and from a non-judgmental perspective.

Culturally Sensitive Therapy

It is one of my priorities to approach my clients from a culturally sensitive standpoint. I strive to continously educate myself, strengthen my cultural awareness and keep an open mind to prevent any type of cultural bias.
