Bipolar disorder therapists & psychiatrists in Valencia, CA

I am a Psychiatric Mental Health Nurse Practitioner (PMHNP) who provides compassionate, evidence-based care for adults. My approach is clinical, trauma-informed, and whole-person, meaning I look beyond symptoms alone and consider the many parts of life that shape mental health. I believe care should feel collaborative and supportive, not overwhelming. My goal is to help you feel understood while creating a treatment plan that fits your life, values, and goals. Whether you are seeking medication management, in-office IV or IM ketamine treatment, or support through a difficult season, I want you to feel safe, respected, and empowered.

You’re capable and use to managing a lot, but lately life feels overwhelming.

I’m Ashley Walay, LICSW, and I work with BIPOC women and LGBTQ+ individuals, professionals, single parents, and military-connected individuals (including spouses, veterans, contractors, and civilian employees) experiencing anxiety, depression, trauma, burnout, chronic stress, and life transitions.

I value clear, direct communication and tailor therapy to your needs, whether you want tools or space to process. Together, we’ll work toward greater clarity, balance, and confidence.

Welcome! I am Dr. Lyssabeth Mattoon, PhD, a clinical psychologist and trauma specialist, skilled at providing individual and family therapy for adolescents, children and adults. My calling in life is to support and empower trauma survivors to harness their inner strength as part of the healing process.

I’m a licensed clinical social worker who specializes in helping children, adolescents, adults, couples, and families navigate anxiety, depression, panic, trauma, PTSD, and other life stressors. With experience in psychiatric crisis care and community outreach, I believe healing starts with feeling safe enough to show up. My goal is to offer real, judgment-free support that meets you where you are and helps you move toward lasting growth.

Hello, I'm Art, a Licensed Marriage and Family Therapist who discovered a passion for helping others later in life. My approach is grounded in motivational interviewing and person-centered therapy, creating a supportive environment where trust, acceptance, and meaningful change can flourish.

As a combat veteran, I understand how difficult it can be to take the first step toward seeking help. I strive to provide a safe, nonjudgmental space where you can explore your experiences, clarify your goals, and grow into the person you want to become.

I have worked with adults, couples, families, and adolescents across a variety of clinical settings, supporting individuals facing trauma, anxiety, depression, psychosis, and life transitions. I am a Certified EMDR Therapist and incorporate EMDR (Eye Movement Desensitization and Reprocessing) along with the Flash Technique to help clients process difficult experiences while minimizing emotional overwhelm.

I also offer Ketamine-Assisted Psychotherapy (KAP), an integrative treatment that can help deepen insight, promote healing, and support lasting change when traditional approaches alone may not be enough.

My goal is to walk alongside you with compassion, curiosity, and respect as you move toward greater healing, resilience, and self-discovery.

I received my PhD from Fuller Graduate School of Psychology and have experience in community mental health, university counseling center, and hospital settings. I also worked as a professor at Fuller Graduate School of Psychology and as a clinical supervisor for doctoral students before transitioning to my current full-time private practice. I enjoy working with clients from diverse cultural backgrounds, and I specialize in the treatment of anxiety, depression, trauma, and spiritual/faith-related concerns. I believe authenticity and humility are essential qualities in an effective therapist, which is why I am committed to my own ongoing personal growth and development as part of my clinical role.
