Trauma and PTSD therapists & psychiatrists in Greenville, TX

Life can get heavy—whether you’re juggling family dynamics, relationship stress, parenting challenges, or just trying to stay afloat. Maybe you’ve always been the dependable one, the person everyone else leans on, but you’re starting to realize it’s time to focus on yourself. You want less tension, more connection, and practical tools that actually make a difference. You’re not after a quick fix—you just want someone real to help you sort things out and walk with you through the hard parts.

I assist children, teens, young adults, and adults work through tough times and difficult emotions, life’s transitions, and relationship challenges. Whether it’s a child with big feelings and educational barriers, a teen feeling isolated and unsure of themselves, or an adult attempting to navigate anxiety, stress, burnout, or identity shifts - I offer a safe, nonjudgmental space to explore what’s going on and facilitate lasting change.

Hello and welcome,

I’m a dedicated therapist with over 10 years of experience supporting individuals through life’s challenges. I am truly passionate about the work I do and feel honored to walk alongside my clients as they navigate difficult moments and work toward healing and growth.

My approach is compassionate, collaborative, and tailored to each person’s unique needs. I strive to create a safe, non-judgmental space where you can feel heard, understood, and supported. I believe that meaningful change happens when we feel genuinely seen and empowered.

I draw from a variety of evidence-based approaches, including Eye Movement Desensitization and Reprocessing (EMDR), Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and other modalities. This allows me to adapt our work together in a way that best supports your goals and experiences.

I have experience working with individuals facing depression, anxiety, relationship challenges, and marital concerns. Whether you are feeling overwhelmed, stuck, or simply looking for support and clarity, I am here to help you move forward at your own pace.

I look forward to the opportunity to work together.
