Evan uses a blend of counseling tools to help clients reach the goals that matter most to them. He enjoys helping people identify their strengths and access their natural healing ability.

Reaching out for therapy can feel like one of the hardest first steps. If you’re here, you’ve already shown courage. I’m here to walk alongside you and provide steady, compassionate support as you move through your healing journey. With several years of clinical experience, I specialize in working with older adults and adults navigating trauma, daily life stressors, life transitions, and other complex challenges. I am passionate about creating a safe, welcoming, and affirming space where clients feel heard, respected, and empowered to explore their thoughts, emotions, and experiences at their own pace. I have experience supporting neurodivergent individuals and members of the LGBTQ+ community, and I am committed to providing inclusive, culturally responsive care. My approach is collaborative and individualized, integrating cognitive-behavioral, person-centered, and mindfulness-based techniques to meet each client’s unique needs and goals. Therapy is not about “fixing” you — it’s about helping you build insight, strengthen coping skills, and reconnect with your resilience. Wherever you are in your journey, we can take the next step together.
