I’m a Psychiatric-Mental Health Nurse Practitioner who is passionate about helping individuals of all ages navigate life’s challenges. I believe true healing involves caring for the whole person—mind, body, and spirit. I strive to build strong, trusting relationships with my patients and work together to create personalized treatment plans that promote growth, resilience, and long-term well-being

I am a Licensed Clinical Social Worker with more than 25 years of experience providing mental health services in behavioral health, crisis intervention, community mental health, and medical settings. I work with children, adolescents, adults, and families navigating trauma, anxiety, depression, life transitions, family conflict, and other emotional challenges.

My approach to therapy is collaborative, compassionate, and trauma-informed. I believe healing happens when clients feel safe, understood, and empowered. I work alongside clients to build on their strengths, develop practical coping skills, and create meaningful, lasting change in a supportive and nonjudgmental environment.

Throughout my career, I have provided therapy and clinical support in outpatient, community-based, hospital, college mental health, and correctional settings. In my private practice, I provide bilingual psychotherapy to individuals and families experiencing trauma, stress, relationship challenges, parenting concerns, and behavioral health issues. I also have extensive experience supporting foster, adoptive, and biological families caring for children impacted by trauma and attachment-related difficulties.

My professional background includes crisis stabilization, risk assessment, treatment planning, wraparound services, and multidisciplinary care coordination for youth and families with complex needs. I am also a part-time lecturer in the School of Social Work at San Diego State University, where I teach and mentor future social workers.

I am passionate about culturally responsive care, equity in mental health services, and helping clients feel empowered throughout their healing journey. I provide services in both English and Spanish and welcome clients from all backgrounds.

I'm a Licensed Marriage and Family Therapist with experience working in community mental health, co-occurring substance use treatment, and residential care settings. I work with adults experiencing anxiety, depression, trauma, substance use challenges, mood disorders, relationship stress, and major life transitions.

I believe therapy works best when clients feel heard, respected and supported without judgement. My approach is collaborative, trauma-informed, and tailored to each client's unique needs and goals. I draw from CBT, motivational interviewing, and strengths-based approaches to help clients build insight, emotional stability, and healthier coping strategies.

I am a board-certified nurse practitioner with many years of experience in healthcare, including primary care, psychiatric mental health, leadership, and wellness-based practice. My background has allowed me to work with individuals facing a wide range of emotional, behavioral, and medical concerns, and I understand how closely mental health and physical health are connected.

I work with adults and couples who feel stuck in patterns that insight alone hasn't changed. Specializing in Veteran care, anxiety, depression, and gender affirming care, I will provide a focused, grounded, and effective approach to therapy. My practice as a Licensed Clinical Social Worker (LCSW) is centered on helping clients clarify what is maintaining their difficulties and develop practical and sustainable ways of shifting them.
