Obsessive-compulsive disorder therapists & psychiatrists in Upland, CA

I am a licensed therapist who specializes in anxiety depression and behavioral addictions such as gambling, gaming, shopping, and technology use. I became an LCSW because, quite simply, I love people and have the deepest respect for all living things. I have a masters in Social work and background in Psychology, Sociology and Education. I believe that every individual has innate strengths and my goal is to help you tap into yours. Whether you are in a difficult life transition, navigating healthy relationships, or looking to understand yourself more deeply, I am here to empower you so that you can move from feeling "stuck" to feeling capable.

Outside of the therapy room, I am a proud mom and dedicated reader. As someone who identifies as a lifelong learner, I will bring curiosity and warmth to every session. In addition to my private practice, I am a crisis clinician. This background has sharpened my ability to remain grounded, and provide a safe, stable space even when a situation may feel the most chaotic.

Great to meet you!

I am a board-certified adult psychiatrist and have been practicing psychiatry since 2017. I work with adults from diverse backgrounds, including professionals, students, parents, women, men, and LGBTQ+ clients, who may be navigating anxiety, depression, ADHD, bipolar disorder, trauma/PTSD, insomnia, OCD, perinatal mental health, stress, or major life transitions. My approach is warm, collaborative, evidence-based, culturally sensitive, and trauma-informed. I offer psychiatric evaluations, medication management, psychotherapy, telehealth, and second opinions, with a focus on helping you feel heard, understood, and supported as we work toward meaningful change.

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.

Welcome! I’m Sarah Stewart, and I specialize in medication management for adults dealing with depression, anxiety, ADHD, bipolar disorder, and other mental health conditions. My approach blends evidence-based care with compassion and collaboration.

I provide a safe, supportive, and nonjudgmental space where we work together to understand your unique needs and goals.

I completed my training as a PMHNP in California and have experience in both emergency and outpatient mental health settings.

I look forward to working together to build a plan that supports your well-being!
