Trauma and PTSD therapists & psychiatrists in Justin, TX

My therapeutic style remains flexible and collaborative, focusing on your individual strengths, needs, and motivation. I consider it a privilege to partner with my clients in this work and to be trusted by them as they share their stories. I strive to create a collaborative space for you to share and examine your own behaviors, feelings, and thoughts; for as Cheryl Richardson has noted, “People start to heal the moment the feel heard.”

Reaching out for support can feel intimidating, but you don’t have to navigate life’s challenges alone. I believe healing begins when you feel truly seen, heard, and accepted. My goal is to create a welcoming, judgment-free space where you can be yourself, explore what’s weighing on you, and discover your own strength. I work with teens, adults, women, and families experiencing anxiety, depression, relationship challenges, life transitions, and the stress that comes with everyday life. As a bilingual counselor fluent in English and Spanish, I also understand how culture, family expectations, and personal experiences can shape our emotional well-being. Together, we’ll build on your strengths, develop practical tools, and work toward the life you want to create—one step at a time.

Welcome! My name is Marquin Decker and I hold a Masters in Clinical Mental Health Counseling from the University of North Texas. I am Licensed Professional Counselor and am EMDR Trained.

I didn’t grow up with the healthy mother-daughter relationship I longed for, and that experience shaped my desire to help others find healing. Today, I’m passionate about helping my clients build the connection, understanding, and relationship they deserve. I specialize in working with women and teens as well as incorporating equine and animal-assisted therapies. I am also trained in play therapy and can work with children ages 6-10yo.

I have 20 years experience, person centered, trauma informed approach. EMDR Certified for trauma. Certified in CBT, MET, and COPSD. Masters Addiction Counselor. Combine Acceptance and Commitment Therapy and EMDR for holistic approach to trauma and negative core beliefs. Experienced PTSD therapist, including military.

Life has a way of presenting us with moments that feel overwhelming, isolating, or simply too heavy to carry alone. Whatever has brought you here today, know this: reaching out is one of the most powerful acts of self-care you can take. I'm a licensed therapist with over 20 years of experience helping adults reclaim their sense of peace, purpose, and connection.
