Obsessive-compulsive disorder therapists & psychiatrists in Petaluma, 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.

I am a dedicated mental health professional who supports children and adults through life’s challenges. I currently provide individual therapy only and do not offer couples counseling. My background in behavioral health and social services, along with hands-on community experience, has shaped my practical, compassionate, and solution-focused approach.

I have worked with individuals involved in the justice system, people living with serious mental illness, children in foster care, and families navigating behavioral or developmental concerns. My experience includes case management, crisis support, employment readiness, behavioral coaching, and coordinating care with medical providers, mental health facilities, and community programs to ensure consistent, long-term support.

I help clients facing depression, anxiety, trauma, life transitions, behavioral challenges in children and teens, parenting and co-parenting concerns, and reintegration after legal involvement. My approach is strengths-based, trauma-informed, and client-centered. I believe everyone has resilience and the ability to grow with the right support.

My style is warm, honest, and structured. I value accountability while always leading with empathy and respect. I focus on building coping skills, improving communication, setting clear goals, and developing practical strategies that support emotional balance and independence.

Hello! I am a Licensed Clinical Social Worker with over 16 years of experience helping people get unstuck.

Armed with a Doctorate in Social Work, my goal is to help you identify the root causes of your challenges and empower you to build a more balanced, fulfilling life.

Hi, I'm Dr. Umugbe — and I'm here to help you make sense of what you're going through.

I'm a board-certified General, Child, and Adolescent Psychiatrist with over 20 years of experience helping children, teens, and adults navigate some of the most challenging mental health conditions out there — psychotic disorders, ADHD, depression, bipolar disorder, anxiety, and more. I see patients via telehealth and also offer in-person visits in Rancho Cucamonga, CA.

Two decades in this field has taught me one thing above everything else: the best care starts with truly knowing the person in front of you. Not just their diagnosis — their story, their symptoms, how long they've been carrying this, and how it's affecting their daily life. That's always where I begin.

As a Psychiatric Mental Health Nurse Practitioner, I am dedicated to helping people feel like themselves again. I provide compassionate, evidence based care for anxiety and depression, ADHD, PTSD, bipolar disorder and other mental health conditions.My goal is to create a judgement free space where patients feel heard and receive personalized treatment that fits their lives

What patterns keep repeating in your life, even when part of you wants something different? I work with infants, children, adolescents, adults, and seniors, with a particular focus on experiences that are hard to put into words: the quiet accumulation of feeling disconnected or unseen, questions around adoption and family origins, infertility, the emotional weight of becoming a parent, and the grief that comes when life takes an unexpected shape. A lot of what brings people to therapy is not a single event. It builds. I trained at UCLA and bring both clinical depth and genuine warmth to this work.

Welcome! I'm Dr. Ben Osevwe, a Doctor of Nursing Practice (DNP) and board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with more than 22 years of experience in mental health care, including over 4.5 years as a PMHNP. I founded Solid Foundation Psychiatry with one mission: to provide compassionate, evidence-based, and personalized psychiatric care that empowers individuals to live healthier, more fulfilling lives.

I work with adolescents and adults ages 12 through 90, providing comprehensive psychiatric evaluations, medication management, and supportive psychotherapy. I believe that effective mental health treatment goes beyond prescribing medication. Every visit is an opportunity to listen, educate, collaborate, and develop a treatment plan that reflects your unique goals, values, and life.

My clinical interests include ADHD, depression, anxiety disorders, bipolar disorder, autism spectrum disorder, obsessive-compulsive disorder (OCD), insomnia, mood disorders, and other psychiatric conditions. Whether you're seeking help for the first time or have struggled with symptoms for years, I strive to create a safe, respectful, and judgment-free environment where you feel comfortable sharing your concerns.

I provide both in-person psychiatric care in Pearland, Texas, serving the greater Houston area, and telepsychiatry to patients in states where I am licensed. My approach combines evidence-based medication management with psychotherapy and lifestyle recommendations.

My philosophy is simple: Every person deserves to be heard, treated with dignity, and given the tools to thrive. I believe healing begins with a trusting relationship, open communication, and a treatment plan tailored to your individual needs.

It is a privilege to be part of your mental health journey, and I look forward to partnering with you to help you build resilience, restore hope, and achieve lasting emotional wellness.
