Trauma and PTSD therapists & psychiatrists in Flower Mound, TX

As a board-certified, doctorally prepared psychiatric nurse practitioner, I treat a variety of mental health disorders using medication management as well as can incorporate psychotherapy within the session based on situational necessity. My focus is across the lifespan, including children and adolescents.

I would describe myself as warm, creative, and affirming. I am a somatic-based therapist trained in EMDR and Somatic Experiencing. In 2016, I earned my Master's degree in Clinical Mental Health Counseling at the University of North Texas. I have worked with a variety of individuals in hospital and outpatient settings. I see clients between the ages of 13 and 75 and am a LGBTQIQA+ ally.

If your internal world feels chaotic, fractured, or heavy, finding a place to land can feel impossible. Maybe you are carrying the weight of complex trauma, navigating a world not built for your neurodivergent brain, or feeling completely disconnected from your own body.

You might feel hesitant to trust a male therapist with your story—especially if your past includes relational trauma, spiritual abuse, or high-control environments. I completely understand. At Quiet Harbor Counseling, safety isn’t something I preach; it is something we build together through steady, respectful, and non-judgmental action.

As a lead therapist with clinical director responsibilities within intensive treatment settings, my days are spent managing complex clinical care.

You may be the person everyone counts on, but that does not mean you are built to carry everything alone

You deserve to feel human, not just functional. You can be competent, capable, and still need help. Those things aren't in conflict.

I work with busy professionals, exhausted parents, healthcare professionals, and LGBTQ+ individuals, who look "fine" but feel lonely, resentful, or stuck in survival mode. You want life to work without running on stress and guilt. Together we'll identify what's draining you and build practical boundaries, routines, and skills that calm your nervous system, protect your energy, and make daily life feel manageable and yours again.
