Everyone wants to have more effective, more efficient brain power. We want to perform at our personal peak, without the use of psychotropic medications. As a Licensed Psychologist and Board Certified Neurotherapist, I treat children and adults using brain training, and individual and family counseling techniques.

We teach the brain to regulate itself using EEG neurofeedback, as well as safe and subtle neurostimulation. While the brain is growing stronger and more adaptive, counseling is provided to assist with problem solving strategies and the cultivation of enhanced emotional and behavioral regulation.

I believe that healing happens when people feel truly seen, heard, and accepted. As a fun-loving person who is still a child at heart, I strive to create a welcoming, authentic, and nonjudgmental space where clients of all ages can feel comfortable being themselves. My goal is to meet you where you are, honor your unique experiences, and walk alongside you as you navigate life’s challenges.

I specialize in working with children, adolescents, and adults who are experiencing the effects of trauma, anxiety, and other challenges that impact daily functioning, relationships, and overall well-being. I am also passionate about providing affirming and supportive care to members of the LGBTQIA+ community, ensuring that every client feels respected, valued, and empowered throughout the therapeutic process. Additionally, I am proficient in American Sign Language (ASL) and am committed to fostering accessible and inclusive care for members of the Deaf and hard-of-hearing communities.

My approach combines compassion with evidence-based practices. I am trained in Cognitive Behavioral Therapy (CBT), trauma-focused counseling, and the SYMBIS Premarital Assessment. Whether you are seeking support for personal growth, healing from past experiences, strengthening relationships, or managing life's stressors, I am committed to helping you build resilience, discover your strengths, and create meaningful change.

I believe that every person deserves a space where they can feel safe, understood, and empowered to grow. My hope is to help you build on your strengths, overcome obstacles, and move toward a life that feels more connected, balanced, and fulfilling.

You’re doing your best—but parenting can feel heavy. Maybe your child is having big emotions, struggling with anxiety, or acting out in ways that worry you. Maybe you’re exhausted, overwhelmed, and wondering if you’re doing enough. You're not alone—and you don’t have to figure it all out by yourself. I work with moms and children (ages 3–17) who are navigating the hard stuff—anxiety, trauma, life changes, or just the emotional weight of everyday life. Whether your child needs support, or you do (or both), I provide a safe, compassionate space where healing begins and hope grows
