Obsessive-compulsive disorder therapists & psychiatrists in Beaverton, OR

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 became a psychiatric nurse practitioner because I did my own work first — after years in a career that looked fine from the outside and felt hollow on the inside, something finally clicked. I live with ADHD and ASD myself, and I'll be direct: it makes me better at this. I'm wired to hold fine details and the big picture simultaneously, connect patterns across a history, and notice what other providers might miss. I work especially well with children and adolescents (ages 6+), perinatal and antepartum folks, LGBTQIA+ individuals, and people who are AFAB or identify as women — many navigating ADHD, autism, PTSD, PMDD, OCD, mood disorders, or a diagnosis that never quite fit. If previous providers didn't get the full picture of you, that's exactly the gap I'm here to close.

I offer a calm, open, and nonjudgmental space where clients can be themselves. I am comfortable talking about difficult experiences, including relationships, grief, anger, addiction, identity, and major life changes. I also value humor, curiosity, and the interests that make each person unique. My goal is to help clients feel understood while also supporting meaningful change.

With decades of experience as a nurse practitioner and over 15 years specializing in mental health, I am committed to understanding each patient's unique story and life experiences. I have a special interest in resiliency and thriving after trauma. I am dedicated to supporting you as you determine the path and pace that best suits your needs.

My name is Angel Kammeyer and I am a Licensed Professional Counselor. I am originally from California but have lived in Oregon since 2014. I received a Master’s Degree in Professional Mental Health Counseling from Lewis & Clark Graduate School of Education and Counseling. I also completed a B.S. in Psychology at Southern Oregon University in Ashland, OR. I have worked in various positions within the community mental health field for over ten years. And I look forward to a long career where my community members, especially people of color, veterans, women, and individuals needing a cheerleader and advocate in their corner, can receive the care that they deserve.

I believe in creating a safe space for individuals to be vulnerable, open, and honest. As we work together, I will use my skills and voice to empower you to share your narrative. Therapy is a journey and I encourage you to take things one day at a time and know that you are worthy and powerful beyond measures. I want to understand you as a person and hope that you will soon be able to see yourself for who you are and not by what society or your diagnosis tells you. Seeking mental health treatment is a big step and I want to celebrate this journey with you.
