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. In my private practice, I bring that exact high-level expertise, administrative precision, and deep trauma training directly to you.

Hi, I’m a licensed therapist who helps people feel more grounded, supported, and in control of their lives. I have a strong background in clinical social work and training in evidence‐based approaches that support healing and real change. I specialize in anxiety, life transitions, relationship stress, and helping clients build healthier patterns. My goal is to create a space where you feel safe, understood, and empowered.

I work with adults 18 and older who feel anxious, depressed, distracted, emotionally overwhelmed, burned out, or unlike themselves. They may be struggling with ADHD, mood changes, stress, sleep disruption, low motivation, or difficulty functioning in daily life. Many are looking for mental health care that feels thoughtful, thorough, and individualized.

I am a Licensed Professional Counselor (LPC-S) with 30+ years of experience. I provide tools, ideas, perspective and encouragement toward your desired goals. I work with individuals and couples on issues such as life transitions, anxiety, relationships, depression, marriage intimacy and many more areas.

I believe healing and growth happen best when people feel safe, accepted, and genuinely cared for. I love working with children, teens, and families, and I strive to create a warm, supportive space where clients can feel comfortable being themselves.

For children, I have advanced training in Child-Centered Play Therapy, which allows them to express feelings, work through challenges, and build confidence through the natural language of play. Often, children communicate much more through play than they can with words, and I enjoy helping them feel understood and supported in ways that fit their developmental needs.
