Bipolar disorder therapists & psychiatrists in Calabasas, CA

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’m a Board-Certified Psychiatric Mental Health Nurse Practitioner who believes mental health care should feel human—not rushed or impersonal.

I provide a non-judgmental space where you can speak openly and feel understood. My approach integrates thoughtful medication management with psychotherapy when appropriate, always tailored to your individual needs.

Diagnosis can be an important part of understanding your experience, but it’s only one piece of the picture. I look at your mental, physical, and emotional well-being, as well as the life experiences that shape what you’re going through.

I offer collaborative, grounded care to help you move toward a more balanced, integrative, and holistic sense of well-being.

Hi, I'm Mitch — a psychiatric mental health nurse practitioner with a Doctor of Nursing Practice from Vanderbilt University. San Diego has been home since 2020, when the Navy first brought me here.

My background includes pediatrics at Children’s Hospital in St. Paul, inpatient psychiatry in Nashville and San Diego, crisis stabilization, and outpatient mental health care. I’ve worked with veterans, college students, LGBTQ+ individuals, people experiencing homelessness, and patients navigating anxiety, depression, bipolar disorder, ADHD, trauma, substance use, and severe mental illness.

I primarily provide psychiatric evaluation and medication management while integrating supportive therapy, psychoeducation, and practical coping strategies into visits. My approach is collaborative, direct, and grounded in helping people improve day-to-day functioning and quality of life.

I look forward to getting to know you.

I specialize in working with adolescents, young adults, and high performers—including Division I athletes, professionals, and anyone striving to meet high expectations. In my work, I’ve learned that growth happens at the edge of comfort—where support and challenge meet. My clients often tell me they appreciate my ability to be both direct and deeply compassionate, creating a space where they feel seen, understood, and encouraged to move forward.

Born in Taiwan, raised in Southern California, and trained in San Francisco and New Mexico, I bring a blend of cultural humility, life experience, and professional training into every session. As an Asian American therapist, I value identity, culture, and lived experience as essential pieces of healing. I aim to create a space where you can show up as your real self—without judgment, without masks.

I believe people carry far more strength, clarity, and resilience than they often realize. My role is to help you understand the emotional patterns and internal narratives that shape your experience, so you can move through life with greater freedom and self‐trust. I’m engaged, attuned, and honest in the room — offering reflection, insight, and steady collaboration as we explore what’s happening beneath the surface. We work at a pace that feels grounded for you, creating space for real change to germinate.

Oh, hey! What a coincidence to meet you here. Everyone seems to be stressed, depressed or plain old over everything and everyone. I get it. I really do. The last thing you want to be doing on your fifteen minute break is looking for someone to talk to about your problems and the general state of the world, but you're here, and I'm available to listen. I'm not going to use a bunch of fancy words I learned in grad school or make you feel like I'm the expert on your life. You know you best.

My passion is for helping others get unstuck and flourish! The focus of my practice is geared toward helping you develop affirming responses and positive interpretations of what has happened in your life. I will help you have agency and integrity in the midst of a life transition or challenge that has you feeling stuck or out of ways to help yourself.
