Addiction therapists & psychiatrists in Richardson, TX

I am a board-certified Family Psychiatric Mental Health Nurse Practitioner. I've worked in different practice settings, including private practice, community mental health, homeless and correctional services, and addiction. I treat and manage a range of disorders ( depression, anxiety, bipolar, schizophrenia, PTSD, OCD, addictions, etc).

I work with adults, couples, and teens, helping people untangle challenges that often feel overwhelming, interconnected, or hard to name. I believe most struggles don’t exist in isolation—they affect our relationships, our emotions, and how we move through the world. My role is to truly get to know you, understand your story, and support you in creating meaningful, lasting change.

My background is both clinical and academic. I hold a Master’s degree in Clinical Mental Health Counseling, along with graduate degrees in Philosophy and Sociology, and a bachelor’s degree in Psychology and Communications. I’m also a doctoral candidate in Educational Psychology. This combination allows me to look at your concerns through emotional, relational, and systemic lenses—not just symptom-focused ones.

I specialize in trauma work, relationship therapy, and working with preteens and teens—who are often misunderstood but incredibly important to support early. I’ve trained in EMDR, Gottman Method Couples Therapy, Emotionally Focused Therapy (EFT), CBT, Art Therapy, and Conflict & Dispute Resolution. Above all, I value creating a space where you feel safe, respected, and genuinely supported.

I’m a Licensed Marriage and Family Therapist and Certified Clinical Trauma Professional with over 15 years of experience supporting adults. I specialize in trauma, anxiety, ADHD, emotional overwhelm, self-worth, and relationship challenges, and I also work with couples seeking stronger communication and connection. My style is warm, collaborative, and relational, creating a space where you can show up as you are. Together, we’ll understand the patterns keeping you stuck, build on your strengths, and create meaningful, lasting change.

As a licensed professional counselor and psychotherapist, my relationship with my client is the most important aspect of the process. I strive for connection and a collaborative spirit. It is always my goal to help the client with their unique and special needs. Whether someone struggles with anxiety, depression, grief, stress, trauma, or general relational issues, I want to develop a plan with them that will be customized to their needs, and specific to what their desired outcome is.

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 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.
