Anxiety and depression therapists and psychiatrists in Sunnyvale, CA

I earned my Master of Arts degree in psychology with a focus on marriage and family therapy to pursue my passion for helping others navigate life's challenges, achieve personal growth, and heal. My education and training have equipped me with the knowledge and skills to provide effective, evidence-based therapy to my clients.

I have 40 years experience in the mental health field in multiple roles, I believe listening and believing in the person is the most important way to practice therapy.

Listen.... Life happens and it's during the tough and difficult times that as a Licensed Clinical Social Worker I'm here to offer a safe space of affirmation.... and accountability

I am a Licensed Clinical Social Worker (LCSW) with more than 4 years of experience. I have experience working with clients facing a variety of emotional and life challenges, including anxiety, depression, stress, adjustment difficulties, trauma-related concerns, and postpartum disorders. I provide evidence-based psychotherapy that supports emotional wellbeing, healthy coping skills, and personal growth in a supportive and nonjudgmental environment.

My therapeutic approach is integrated and tailored to meet your unique needs. I often draw from Cognitive-Behavioral Therapy (CBT) and Motivational interviewing.

I graduated from Fresno Pacific University-Biblical Seminary in 2014 and obtained my license as a LMFT in 2018. My experience has been working with children, adolescents, families (4 years) and adults (11.5 Years). I have 11.5 years' experience with co-occurring disorders to include severe mental illness and trauma. I have utilized but not limited to the following evidence practices and modalities -ACT, Strength-Base, Family psychoeducation, DBT, CBT, and person centered. I am currently expanding my education/training in Internal Family Systems.

I believe therapy should feel like a space where you can finally exhale. I strive to create an environment that is supportive, honest, and free of judgment; a place where you feel truly seen and emotionally safe. My approach is collaborative and practical. I don’t just help you understand why you feel the way you do; I help you build real tools to navigate it.

I earned my degree from Cal State Fullerton and have extensive experience working in addiction treatment, eating disorder recovery, and women’s issues. Supporting women is especially meaningful to me. I am deeply passionate about helping women navigate challenges related to self-worth, body image, relationships, boundaries, life transitions, and identity. I understand how trauma, societal expectations, and relational dynamics can shape how women see themselves, and I approach this work with both compassion and clarity.

Together, we focus on strengthening mindfulness, emotional regulation, distress tolerance, and communication skills in ways that feel realistic and sustainable. I blend insight-oriented exploration with concrete strategies, because meaningful change happens when insight meets action. My goal is to help you better understand your patterns, feel more confident managing your emotions, and move forward with greater clarity, self-trust, and resilience.
