Obsessive-compulsive disorder therapists & psychiatrists in Lancaster, 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.

I have experience working with children, youth, adults, families, couples but in the last few years, I have shifted my main focus to work with adults who are struggling with anxiety, trauma and depression. I’ve worked in the mental health field for 22 years and been practicing as a therapist for about 10 years. As a licensed marriage and family therapist, I believe that prioritizing mental health is key to happiness and stability in life. Seeking help can be difficult, so congratulations on taking your first step to start therapy.

Welcome! As a bilingual licensed therapist, I am passionate about helping individuals navigate life’s challenges by providing emotional support and personalized coping tools. Whether you’re taking your first step into therapy or continuing a journey you’ve been on before, I’m committed to creating a safe space where all of your feelings and life experiences are welcome.

I specialize in anxiety, depression, trauma, and work with the Spanish-speaking and LGBTQ community as well.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.
