Obsessive-compulsive disorder therapists & psychiatrists in Petaluma, CA

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.

Hi, I’m Eliza Rivera-Mitu, a board-certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. I specialize in treating ADHD, anxiety, depression, and mood disorders, as well as the psychiatric challenges in autism. With a background in both psychiatry and family medicine, I take a holistic approach that considers the whole person—not just the diagnosis. I'm passionate about helping you feel heard, empowered, and supported in your mental health journey.

I am a Psychologist who is passionate about helping women through life transitions and reproductive challenges, including pregnancy, motherhood, infertility, loss and trauma.

Do you ever wonder if you, a loved one, or a friend have ADHD or Autism? You deserve a therapist who truly gets it and I am the one for you. Neurodiversity has been the heart of my work for most of my 40 years in practice. I spent 15 years at Kaiser, where I helped create and lead autism programs across Southern California. Today I'm a Licensed Marriage and Family Therapist in California, and I focus on adults.

avigating emotional distress or long-standing conflict can feel like being fractured, but healing often begins with finding a reliable and experienced partner. I am Dr. Julie Cohen, a Clinical Psychologist with over 45 years of experience. I have spent my career helping individuals, couples, and families resolve conflict—whether it’s occurring in the living room or the workplace. I specialize in treating depression, anxiety, and stress, particularly for those who are ready to dive into their inner experience to improve how they feel about themselves and their relationships. I feel privileged to help my clients achieve their goals and improve their lives by providing the expert, seasoned care necessary to handle even the most complex challenges with precision and kindness.

I believe that the foundation of our work is a relationship of absolute trust and safety. My extensive training allows me to look at your life through a wide lens, understanding how your past experiences and upbringing shape your current personality and challenges. I encourage an honest and direct dialogue, as that is where true mutual understanding begins. When I am not working with clients, I value the perspective that comes from a long career dedicated to human behavior, often finding restoration in the very principles of balance and growth that I share in my sessions. I want my clients to feel safe and empowered during their time with me, knowing they have a safety net of four decades of clinical expertise behind them.
