Bipolar disorder therapists & psychiatrists in Portland, OR

I believe healing begins with connection- to ourselves, to others, and to the world around us. As a psychiatric nurse practitioner, I create a space where you can feel seen, understood, and supported as we navigate life’s challenges together.

Hello, and welcome! My name is Convince Njiru and I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP). I’m passionate about providing compassionate, evidence-based mental health care that empowers individuals to achieve balance, healing, and personal growth.

I earned my Master of Science in Nursing from Purdue University , where I received specialized training in psychiatric assessment, diagnosis, and treatment across the lifespan. My clinical experience includes working with individuals facing depression, anxiety, ADHD, bipolar disorder, Schizophrenia, trauma-related disorders, and other mental health challenges.

In my practice, I take a holistic and collaborative approach — integrating medication management, psychotherapy techniques, and lifestyle interventions to create individualized care plans. I believe that mental health care should be accessible, judgment-free, and tailored to each person’s unique story.

Whether you’re seeking help for the first time or continuing your mental health journey, I strive to provide a safe, supportive space where you can feel heard and understood.

I am a board-certified Psychiatric Mental Health Nurse Practitioner who provides compassionate, evidence-based psychiatric care for adults navigating anxiety, depression, stress, burnout, life transitions, and mood-related concerns. My goal is to create a safe, respectful space where clients feel heard, understood, and supported.

I take a personalized approach to care, recognizing that mental health is influenced by many factors, including life experiences, relationships, work stress, sleep, physical health, and daily functioning. I work collaboratively with clients to better understand their symptoms, identify treatment goals, and develop a plan that supports stability, clarity, and improved quality of life.

As a board-certified psychiatric mental health nurse practitioner, my path to psychiatry was shaped by over eight years as a bedside nurse. I watched patients face fear and uncertainty that often went unaddressed — and I knew those feelings deserved their own dedicated space. That's what brought me to outpatient psychiatry. I work with children, adolescents, adults, and older adults, and I have experience treating depression, anxiety, bipolar disorder, ADHD, PTSD, OCD, trauma, substance use, and more — including LGBTQ+ individuals and those navigating maternal mental health, grief, and chronic illness.

I've spent 14 years working with people who are dealing with things that don't have easy answers — addiction, trauma that won't stay in the past, chronic illness, grief, and the invisible weight of caregiving for someone else. I'm a Licensed Professional Counselor based on the Oregon coast, and I work with adults across Oregon via telehealth. I'm direct, warm, and a little bit funny — therapy doesn't have to feel like a performance. I'll tell you what I actually think, ask you questions that get somewhere, and we'll adjust the approach based on what's actually helping you. I treat anxiety, OCD, depression, PTSD, substance use, and a range of life transitions — including the ones that hit when you're already tired.

Life’s challenges can feel overwhelming at any stage—whether you’re navigating adolescence, adulthood, relationships, parenting, or the transitions that come with aging. Anxiety, depression, grief, and life changes can disrupt how you think, feel, and connect with others. Therapy offers a supportive place to slow down, feel understood, and develop effective tools to move forward with greater clarity, balance, and confidence.

Life doesn’t come with a roadmap—and when stress, anxiety, grief, or major changes pile up, it’s easy to feel overwhelmed or alone. Therapy offers a place to slow down, feel understood, and begin finding your way forward with clarity and confidence.

I provide a compassionate, supportive space where you can explore what’s holding you back, build resilience, and reconnect with your inner strength. Together, we’ll work toward meaningful change so you can feel more confident, grounded, and at peace.

Who I Work With

I work with individuals across the lifespan, including:

• Teenagers and young adults
• Adults experiencing anxiety, depression, or life transitions
• Women and single mothers
• Men facing male-specific challenges
• Older adults navigating aging-related concerns

I also work with couples, parents, and business partners, helping strengthen communication, emotional understanding, and connection.

In today’s world, many of us are carrying more than just personal stress. Climate concerns, the pandemic, economic instability, political division, and rapid cultural change have created a sense of collective trauma that deeply impacts our mental health. In my work, I recognize that individual struggles don’t exist in isolation—they are shaped by the larger systems and environments we live in.

My goal has always been to support people navigating trauma, personality disorders, depression, and anxiety by exploring the deeper layers of the psyche. Together, we work to build self-awareness, understand unconscious patterns, and develop practical tools that support meaningful and lasting change. I work with a diverse range of clients, from adolescents to older adults (ages 13–65+).

My therapeutic style is eclectic, integrative, and holistic. I draw from a variety of approaches to meet each client where they are, while also acknowledging how societal structures can influence mental health. Areas of particular interest in my work include complex trauma, the psychological impacts of modern economic systems, eco-anxiety, non-dogmatic spirituality, and emerging perspectives in psychedelic-assisted therapy.

Above all, I believe healing happens in a space of safety and authenticity. I strive to create a judgment-free, inclusive environment where clients are met with unconditional positive regard, empathy, validation, and genuine care.

If you’re feeling overwhelmed, searching for deeper understanding, or simply looking for support, you are welcome to reach out.

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.
