Bipolar disorder therapists & psychiatrists in Costa Mesa, CA

I’m Matthew “Matt” Tapia, a Licensed Marriage and Family Therapist (LMFT) offering online therapy in Arizona and California. I specialize in neurodivergent-affirming care for autistic people and people with ADHD. I also help clients navigate anxiety, depression, trauma and PTSD, relationship concerns, and caregiver stress.

If daily demands leave you overwhelmed, misunderstood, or unsure where to begin, we can start with what matters most to you. My style is warm, practical, and collaborative, with room to explore your experiences and develop skills you can use in everyday life.

I work with children, teens, adults, and families. I hold a Master of Arts from Santa Clara University and am also a Board Certified Behavior Analyst (BCBA). My background in family therapy and behavioral science helps me understand how emotions, relationships, daily routines, and your environment influence one another.

Together, we can work on managing strong emotions, communicating your needs, strengthening relationships, and creating routines that fit your life. Therapy respects your communication preferences, sensory needs, strengths, and personal goals.

All sessions take place through secure telehealth. I accept insurance through Headway, where you can check your coverage and view available appointments.

Hi, I’m Tina Chen, a Psychiatric Mental Health Nurse Practitioner dedicated to helping clients feel their best. I specialize in treating depression, anxiety, and ADHD, and I combine medication management with practical tools from CBT and positive psychology. With advanced training from California Baptist University and National University, I focus on creating a supportive, collaborative space where you can build confidence, resilience, and balance in your everyday life.

I’m Chinenye Udoh, MSN, PMHNP-BC, FNP-C, a dual board-certified Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. I work with adolescents and adults navigating ADHD, anxiety, depression, bipolar disorder, trauma-related concerns, schizophrenia, and other mental health challenges.

Many of the people I work with have spent years knowing that something doesn’t feel quite right but struggling to put it into words. You may be having difficulty focusing or completing tasks, experiencing overwhelming anxiety, struggling with motivation, noticing significant changes in your mood, or simply feeling exhausted from trying to manage everything on your own. My goal is to provide a space where you feel heard rather than judged and understood rather than rushed.
