Bipolar disorder therapists & psychiatrists in Santa Rosa, 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.

As a Licensed Psychotherapist with over 17 years of clinical experience, I have dedicated my career to helping children, adolescents, adults, couples, and families navigate life’s challenges and discover their strengths. In addition to my private practice, my work in a hospital Emergency Department has provided me with valuable experience supporting individuals and families during some of their most difficult and vulnerable moments.

I am a clinical psychologist licensed in California and Illinois, and can see clients from both states. I have worked with clients in the areas of depression, anxiety, relationships issues, addictions, stress management, sport and performance, bipolar disorder, and binge eating disorder. My therapy style is personable, connected, focused, and attuned.

Hola and Bienvenidos! My goal in working with you is to get to know you, be an available and a trusted ally.

If you feel overwhelmed by a sea of things outside of your control— facing a new health diagnosis, a deep loss or the weight of anxiety—I am here to help you anchor yourself. I am a multi-state licensed therapist (CA, MA, WA, MD, SC) seeing clients online coast to coast on Tuesdays and Fridays. I am dedicated to helping you move from feeling boxed in to feeling empowered to make changes. My approach is centered on controlling the controllables. We will work together to identify the practical steps you can take today whether you are navigating through a career change or new stage in your life, or processing the deeper emotional impact of grief, trauma or chronic illness. I look forward to helping you find your footing and reclaim your sense of agency.

I am a Licensed Marriage and Family Therapist (LMFT) with a Master’s degree in Marital and Family Therapy from the University of San Diego. Since graduating in 2021, I have worked with adolescents, adults, and couples in community mental health and outpatient settings.

I became a therapist because I wanted to make a meaningful difference in people’s lives. I’m passionate about helping others better understand themselves, work through challenges, and become the best versions of themselves. I believe everyone deserves the opportunity to heal, grow, and create a life that feels fulfilling and authentic to them.

I have experience supporting clients navigating depression, anxiety, mood and personality disorders, neurodivergence, relationship difficulties, life transitions, and general life stress. I believe therapy should be a space where clients feel safe, supported, and genuinely heard.

My approach is collaborative and individualized, drawing from modalities including CBT, DBT, Narrative Therapy, and EMDR. I work alongside clients to better understand patterns, build coping skills, improve relationships, and create meaningful change aligned with their goals and values.
