Dr. Seima Diaz

Hello there!

I'm a Licensed Marriage & Family Therapist in CA with advanced training in attachment-based therapy and DBT. I'm a former Child Development lecturer at Chapman University. I combine insight with practical tools to create meaningful, measurable change in adolescents and adults. I help my clients address their patterns that leave them feeling unseen or over extended. I will help you understand how early dynamics and experiences shaped your self-worth, attachment style, and boundaries.

I can help you with anxiety, perfectionism, emotional reactivity, relationship conflict, body image concerns, and the impact of narcissistic or critical parenting. A typical treatment plan includes attachment-focused insight, skills for regulation and boundaries, and practical communication tools. You can expect greater emotional stability, clarity, and confidence in relationships.

Your experience will be warm, collaborative, and direct—balancing deep exploration with practical tools. You'll gain clarity about your patterns, learn concrete regulation skills, and feel both supported and appropriately challenged as you grow.
