I'm so glad you're here! Running has been a cornerstone in my life and has been transformative in the lives of many of my athletes. The all-encompassing nature of this sport allows it to become a uniquely powerful tool for improvement whether it's fixing old injuries or learning to be kind to yourself. My goal has always been to help others understand what their best effort looks like and learn to be proud of it, separating self-worth from outcome. Whether you're beginning the journey towards your first 5k or aiming to win an ultra, I'm excited to hear from you and help you develop towards your goals!

My Philosophy

Training should be a two-way conversation between coach and athlete

Individualized & Intelligent

Every runner is unique. I work to understand your whole life: how running fits into it, what motivates you, and how to make training sustainable and enjoyable for the long term.

Injury Prevention First

Through targeted strength programs and smart training progression, I help athletes overcome persistent injuries like Achilles tendinopathy and ITBS while building resilient, powerful running.

What Athletes Say

Caroline running

"I started working with Matt just about a year ago. At the time, I had been looking for a more structured approach to my training. I quickly realized Matt showed the same level of investment and enthusiasm into helping others achieve their goals, as I did to working toward my own. Matt takes a proactive approach to his coaching, through a deep understanding of evidence based practices and continuous pursuit to learn more. He meets you where you're at as an individual and what's going on in your life, which is fosters a relationship of empowerment and collaboration between athlete + coach. Personally, I've seen a tremendous improvement in my race performances (trail + road) as result. But beyond that, I've noticed an immense amount of growth in myself since working with Matt."

— Caroline Alcorta
Joel running

"Working with Coach Matt has been incredibly eye-opening. After five years of trail running, I came to Matt with a goal: train smarter, avoid another femoral stress fracture, and get faster for the Seattle Marathon. He delivered on all fronts. Matt's approach is both data-driven and deeply personal—he took the time to understand me as an athlete and made it clear this was a two-way street. His programming is creative, individualized, and always backed by a strong 'why' behind each workout. I finally feel like I know what I'm doing as an athlete and how to keep doing it without getting hurt."

— Joel Gartenberg
Julien running

"I hired Matt after just one conversation about training. The depth of his knowledge of running and his passion for the work of coaching were immediately apparent. Throughout the following months, I became a totally different athlete. Matt works especially well with persistent injuries. Through the strength programs that I received, I found my injuries retreating and my running imbued with a whole new type of strength. He is also a very holistic coach who will try to understand your life, how your running fits into it, and what motivates you to run. Matt bears the mark of a truly great coach: he deftly passes on not only the routine motions of training but his deep knowledge of its methods."
