Mission Statement

Getting kids off Screens and biking through Trees
Pacific Mountain Biking is a youth bike skills program founded by lifelong friends, riders, and outdoor enthusiasts in the Seattle area in 2020: at a time when the world was indoors, disconnected, and overloaded by screens.  Now based in San Diego, we’re proud to offer high quality classes and camps across the region’s trail systems. 
Our small group sizes of 5:1 reflect our commitment to developing strong riders by ensuring each student receives personalized attention and immediate care during their classes.

Hey all! I’m Daniel; nature lover and founder of Pacific MTB. I grew up riding the trails of the greater Seattle area where my love for the outdoors was shaped by countless hours on two wheels.  After moving to San Diego in 2019, this connection only deepened with the new terrain.

With years of youth coaching experience and a background in biochemistry, nanoengineering & management consulting, Pacific MTB is a combination of a love for mountain biking & teaching with a structural focus geared towards safety, growth and strong communication.

Mountain biking teaches more than just technical skills: it teaches resilience, adaptability, perseverance and confidence.  I created Pacific MTB to help young riders overcome challenges, push past their limits and discover their true potential through real world interactions. Nothing beats sharing the joy of riding and exploring nature with the next generation in an increasingly digital world.

Let’s ride, shred on!
