Aaron is the founder, President, and Lead Developer of Trillium. He has over 12 years’ experience as a web developer with over 8 years in public transportation. A strong background in communication and writing enables him to communicate technical concepts to diverse audiences, and to bridge communication divides between information technology, marketing, customer service, and operations disciplines.

A long-time cyclist and transit rider, Aaron’s core interest is making sustainable transportation easier to understand and use. His work at Trillium reflects his passion for using modern technology and clear communication to make transportation sustainable. He frequently speaks at conferences regarding open data and digital communications strategy for public transportation.

His experience in transportation encompasses fixed-route public transit, demand-response transportation, private transportation, and active transportation modes. Skills include developing data standards, web-application design, digital communications and marketing strategy development, and public speaking about connecting travelers with technology.

Aaron’s commitment to public transportation began as a co-founder of Green Wheels, an advocacy organization for transportation choices in Northern California, in 2006. Realizing the need for services and software to help transit agencies embrace modern technology and to communicate more effectively with their customers, he founded Trillium in 2007.

Originally from Northern California, Aaron now calls Portland, Oregon home. He enjoys traveling throughout the world and experiencing diverse transportation systems. Bike touring and backpacking are some of his favorite ways to see new places.
