Obsessive-compulsive disorder therapists & psychiatrists in Lancaster, CA

Hello! My approach is centered in the belief that authentic connection with ourselves and others heals. Therapy is an opportunity to dive deep, to develop greater self knowledge, to come into wholeness, accepting and integrating all of our parts and aligning our lives with our Truth and the fullness of who we are. I look forward to the opportunity to support you.

My name is Dr. Rosalyn Warren, and I am a Licensed Clinical Social Worker with extensive experience helping children, adolescents, young adults, adults, and older adults facing anxiety, depression, grief and loss, trauma, addiction, and suicidal thoughts. I am a certified informed addiction medicine professional, a certified grief and loss professional, and a trauma-informed professional. I have been an MSW for 30 years, licensed as an LCSW for 20 years, and I am currently pursuing my doctorate in Social Work at USC.

I know how heavy life can feel when you’re carrying pain, uncertainty, or self-doubt. But I believe, as a wise old wizard once said, “Happiness can be found even in the darkest of places, if one only remembers to turn on the light.” My role is to help you find that light again. I work with Gen Z and Millennial adults facing anxiety, depression, trauma, bipolar disorder, ADHD, and more. Through integrative, culturally responsive care, I combine evidence-based psychiatry with holistic strategies to help you feel heard, supported, and empowered to create a life that aligns with your true self.

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.

I am a compassionate and dedicated psychotherapist who values creating a genuine, trusting connection with each client. I believe therapy works best when you feel safe, understood, and able to be your authentic self.

I earned my Master of Arts from National University and completed doctoral-level training at Pacifica Graduate Institute. My clinical training and professional experience have provided me with a strong foundation in working with individuals from diverse backgrounds.

I have experience working in drug and alcohol rehabilitation settings, where I supported individuals navigating substance use, trauma, and related mental health challenges. I also have experience working with men’s mental health concerns, including emotional regulation, identity, and relationship issues.

I use an integrative approach, drawing from Cognitive Behavioral Therapy (CBT) and Psychodynamic Therapy to help clients understand both present challenges and underlying patterns. I work with individuals experiencing anxiety, depression, stress, trauma, relationship concerns, and life transitions, helping them build insight alongside practical tools for lasting change.

Outside of my work as a therapist, I value staying active and maintaining a strong mind-body connection. I spend much of my time weightlifting, boxing, practicing jiu-jitsu, and participating in CrossFit and Olympic lifting, and I also enjoy running. These practices help me stay grounded and bring a perspective of discipline, resilience, and balance into my work with clients.
