Trauma and PTSD therapists & psychiatrists in Long Beach, CA

My name is David Marquez and I am a Licensed Clinicial Social Worker (LCSW) in California. I have been a social worker for over 10 years and graduated from San Francisco State University. As a Latino therapist, I’m especially passionate about serving LGBTQ+ and BIPOC communities. I offer therapy in English and Spanish, and I bring cultural awareness, warmth, and real conversation into the room. Your identity, experiences, and personality aren’t side notes here — they’re part of the story we honor. Therapy with me is collaborative, affirming, and occasionally sprinkled with humor — because sometimes the most healing moments come right after we say, “Ohhh... that makes sense.”

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a DNP (Doctor of Nursing Practice) degree from the University of Massachusetts Global.

The therapist partners with the client to clarify their thoughts to provide new skills and insights which increase the client coping skills and resiliency He educates and teaches about psychiatric disorders as depression and anxiety and the skills to overcome tthm.
