Most people who end up in my office didn’t plan on being there. Maybe things have been building for a while — stress at work, tension at home, a relationship that’s fraying at the edges — and you’ve finally hit a point where you know something needs to change. Or maybe you’ve never really talked to anyone about what’s going on inside, because that’s just not what you do. Either way, you’re in the right place.

I work with adults and teens who are carrying more than they let on. A lot of my clients are men who have spent years being the capable one, the strong one — and are quietly exhausted. I also work with families navigating real conflict, teens who feel genuinely misunderstood, and people dealing with the harder stuff: trauma, substance use, or life circumstances that have gotten complicated. Whatever brought you here, I’m not going to make you fit into a box.

My approach is direct but never harsh, and always built around your actual life — not a textbook version of it. We’ll figure out what’s really going on beneath the surface, build skills you can use right away, and work toward something that feels like solid ground again.

Nathan is a Licensed Clinical Social Worker in Colorado and California with over a decade of experience, including work in juvenile justice, inpatient psychiatric care, eating disorders, and substance use. He has served as Clinical Director at several treatment facilities. If therapy hasn’t worked for you before, he genuinely wants to know why — and do something different. Originally from California, Nathan now calls Colorado home, where he spends his time outdoors with his wife, their daughter, and their Dutch Shepherd.

I am a California native who has made Colorado home for the last several years. I live for the moments I get to spend in nature with my incredible wife, our infant daughter, and our beloved Dutch Shepherd.
