ADHD therapists and psychiatrists in Manhattan Beach, CA

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.

Ollie Maggi works with individuals and couples to help navigate life and relationship stressors. As an LMFT and school psychologist, she specializes in neurodivergence and ADHD. She also has four years of specialized sex therapy training. Ollie assigns homework, so be ready for check-ins and an accountability partner.

A core priority in my work is helping clients reclaim the power of their voice. Therapy is most meaningful as a collaborative process where you are not only heard, but truly attempted to be known. As an Iranian American therapist, I understand the richness and complexity of holding multiple cultural identities. I especially enjoy supporting Highly Sensitive People (HSPs), as well working with teenagers and adults navigating identity formation, relationships, and the often tender process of growing into themselves. There’s room here for deep healing, honest conversations, and the occasional ‘okay, but why is my brain doing THAT?’

I offer a grounded, practical, and collaborative space to help you heal, grow, and move forward with clarity. If you're feeling stuck in old patterns or seeking a deeper sense of direction, we will work together to make sense of your story and build a path toward lasting independence.

Reach out today to begin.

If you're looking for an empathic, reliable therapist, I strive to provide a supportive and nonjudgmental space where you can explore current stressors, past experiences, relationship dynamics, and develop a deeper understanding of yourself. I believe meaningful change begins with feeling heard, understood, and safe enough to be authentic.

I work with individuals, couples, and families navigating trauma, grief, anxiety, and relationship challenges. If you're seeking more short-term coping, we can explore the patterns shaping your experiences to support lasting, meaningful change. My approach is trauma-informed and attachment focused - always guided by your goals. Therapy is a warm, collaborative space where we process experiences, strengthen communication, and build more secure, fulfilling relationships.

Deep listening is a gift that empowers individuals to reflect and change

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.

I specialize in treating schizophrenia, bipolar disorder, PTSD, depression, anxiety, etc.

My academic background includes a Post-Certificate DNP in Psychiatric Mental Health from the University of Illinois Chicago, a Doctorate of Nursing Practice from Texas Tech University, and a Master of Science in Nursing from Touro University. I also completed an intensive NP residency focused on advanced psychiatric care, crisis stabilization, and forensic psychiatry, which further strengthened my clinical expertise.

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

My approach is grounded in trauma-informed, individualized care. I take time to fully understand your history, concerns, and goals before collaboratively building a treatment plan tailored to you. I have also served on health policy committees and presented at national nursing conferences, reflecting my commitment to psychiatric care.
