Trauma and PTSD therapists & psychiatrists in Sunnyvale, CA

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.

The focus is to help individuals heal, energize, and become aware of their inner strengths. I achieve this by providing a neutral safe space, listening to your concerns, and customizing a treatment plan. I help individuals focus on the Solution.

Great to meet you!

As a Licensed Clinical Social Worker, I believe prioritizing mental health is key to happiness and stability in life. Asking for help can be one of the toughest challenges, so congratulations on taking that first step! I’ve been practicing for 10 years, and my main focus are adult clients who are struggling with PTSD, anxiety and depression.

I believe healing begins with meaningful connection. My work with cancer patients and their families has deeply shaped my understanding of pain, loss, resilience, and the complexities that relationships face during times of crisis. I support adults of all ages in navigating challenges such as anxiety, depression, loneliness, grief, and relationship concerns, offering both compassionate guidance and practical, effective tools for growth and healing.

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 was always drawn to people who went unseen or unheard. Others told me I had a calm voice and that they could tell me anything. That led to a lifelong study of how people free themselves from their own patterns, later deepened by psychoanalysis and professional work in eating disorders, addiction treatment, and managed care settings like Kaiser.

I help clients break the cycle of self-defeating patterns by exploring the lasting impact of early attachment wounds—especially the often unspoken pain of under-mothering and emotional neglect. My approach is grounded in compassion, curiosity, and the belief that healing begins when we de-stigmatize shame and make space for our unmet needs.

With certification in EMDR and advanced training in Internal Family Systems (IFS), I support clients in working through trauma, grief, and relational challenges. My background also includes working with first responders and professional athletes navigating high-pressure roles and emotional resilience.

Whether you're facing anxiety, grief, or feeling stuck in old patterns, I provide a steady therapeutic presence—offering insight, empathy, and deep respect for your healing process. Together, we work toward greater self-trust, healthier boundaries, and a renewed sense of wholeness.
