Obsessive-compulsive disorder therapists & psychiatrists in San Mateo, CA

I am a licensed therapist who specializes in anxiety depression and behavioral addictions such as gambling, gaming, shopping, and technology use. I became an LCSW because, quite simply, I love people and have the deepest respect for all living things. I have a masters in Social work and background in Psychology, Sociology and Education. I believe that every individual has innate strengths and my goal is to help you tap into yours. Whether you are in a difficult life transition, navigating healthy relationships, or looking to understand yourself more deeply, I am here to empower you so that you can move from feeling "stuck" to feeling capable.

Outside of the therapy room, I am a proud mom and dedicated reader. As someone who identifies as a lifelong learner, I will bring curiosity and warmth to every session. In addition to my private practice, I am a crisis clinician. This background has sharpened my ability to remain grounded, and provide a safe, stable space even when a situation may feel the most chaotic.

Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.

If trauma is still running your life, OCD has you trapped in cycles you can't break, or depression has left you feeling numb, stuck, and disconnected from the life you used to want—I want you to know: this can change, and you don't have to face it alone.

My path to this work started with my own mental health journey. I know what it feels like to struggle from the inside—and I know how life-changing the right support can be. That's exactly why I bring deep empathy, zero judgment, and evidence-based tools designed to create real, lasting change—not just coping, but building a life that feels like yours again.

If you’re feeling overwhelmed by anxiety, navigating relationship challenges, or trying to manage things like ADHD, PMDD, or hormone-related changes, you don’t have to figure it all out on your own. I know how much life can demand—balancing work, relationships, family, and everything in between can leave very little space to actually slow down and check in with yourself.

I work with adults and couples, and I really value creating a space that feels safe, supportive, and easy to show up in. My style is laid-back and genuine, and I care a lot about building a strong, collaborative connection so therapy feels helpful—not intimidating.

Hello! I’m a board-certified Psychiatric Mental Health Nurse Practitioner providing personalized care through telehealth. I work with adults experiencing anxiety, depression, trauma, ADHD and stress-related challenges. My goal is to create a space where you feel comfortable, heard, and supported without judgment. I take a collaborative approach to care and include medication management when appropriate. I also offer services in both English and Spanish.

I’ll help you develop self-awareness, emotional resilience, and meaningful connection. We will seek to understand how your unique past contributes to who you are in the present. My goal is to help clients identify goals that will help them increase their self-understanding, emotion regulation, and relational satisfaction.

I am a Licensed Marriage and Family Therapist with experience working with children, adolescents, adults, couples, and families. My clinical background includes supporting individuals experiencing anxiety, depression, trauma, relationship challenges, life transitions, and eating disorders. I also have experience incorporating play therapy when working with children and developmentally appropriate interventions for adolescents.

I believe therapy should be individualized rather than a one-size-fits-all approach. I begin with a comprehensive assessment to understand your experiences, concerns, strengths, relationships, and goals for treatment. From there, we work collaboratively to develop a treatment plan that feels meaningful and realistic for you.

My approach is warm, supportive, and collaborative while also providing structure and guidance when needed. I integrate evidence-based approaches, including Dialectical Behavior Therapy (DBT), trauma-informed interventions, and other therapeutic modalities based on your individual needs. Whether you are working through past experiences, navigating current challenges, strengthening relationships, or simply wanting to better understand yourself, my goal is to create a safe and welcoming space where you feel heard, supported, and empowered to make meaningful changes in your life.

I specialize in supporting people who feel overwhelmed by anxiety, depression, stress, ADHD, trauma, life transitions and much more. I have extensive experience working with high acuity teens, and I also work with adults of all ages who are navigating imbalance, self-acceptance uncertainty, or emotional overload. I support parents who need guidance in understanding their child’s needs or simply a calm place to process their own feelings. No matter your age or background, if you are struggling to find balance and peace in life, I am here to help.

My approach begins with the belief that life poses great challenges for all of us. Through these challenges, we develop adaptive patterns that may help us survive but can also bring disharmony. I aim to help you bring awareness to these patterns, loosen their grip, and reshape them so you can find greater balance and harmony in your relationship with yourself, others, and the world.

With over 15 years of clinical experience across inpatient psychiatry, maternal health, and advanced practice, I am deeply committed to delivering compassionate, evidence-based mental health care to every person I serve.

This background gives me a uniquely broad, whole-person perspective on psychiatric care across the lifespan.

I have also served on health policy committees and presented at national nursing conferences, reflecting my commitment to psychiatric care.
