I specialize in working with individuals navigating challenges such as ADHD, PTSD, anxiety, and personality disorders. My approach is rooted in deep clinical assessment, evidence-based therapy, and a holistic understanding of mental health. Whether you're seeking clarity through psychological testing or transformation through therapy, I tailor my work to your unique needs—not just a diagnosis. With advanced EMDR training, DBT certification & coaching skills, I integrate powerful, research-supported techniques to help you process trauma, regulate emotions, and build sustainable change. I draw from CBT, EMDR, DBT, and mindfulness.
What sets my practice apart is its whole-person focus. In our sessions, I’ll help you explore foundational elements of well-being—like sleep, gutbrain health, diet, exercise, and social connection—because mental health is interconnected with every part of your life. We'll examine your lifestyle, dive deeply into your story, and build a plan together.
As a once divorced and homeless veteran with TBI, PTSD, and depression, I felt lost. Through excellent therapy, I rebuilt my life and am now a happily remarried father of four, living with purpose. Now, I’m here to help you find the same transformation and resilience in your own life.

I work with clients who may be struggling with anxiety or trauma related to their relationships or family. During our initial sessions, we will delve deeply into the issues at hand, and collaborate to create a plan for addressing them in a way that helps you get your life back. Most of my clients see a gradual lifting of symptoms within the first month and sustained improvement thereafter.

I often use Cognitive Behavioral Therapy and DBT in my practice. In your first session, we'll explore what brought you to therapy and then decide the most appropriate ways to help you make progress. With CBT, we'll look at how your thoughts affect your emotions and experience. During treatment, I'll help you learn how to push back against those thoughts to change your feelings for the better.
