Obsessive-compulsive disorder therapists & psychiatrists in Valencia, CA

I’m someone who truly listens and strives to meet each person exactly where they are. My style is adaptive, reflective, and flexible. I bring authenticity, compassion, and a good sense of humor into my work because I believe that laughter and honesty can be just as healing as insight. I was inspired to become a therapist by my own desire for the kind of support I would have wanted, and I aim to offer that same understanding and care to my clients. People often describe me as warm, genuine, and empowering. I am someone who helps them feel deeply heard and supported while encouraging growth in meaningful ways.

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.
