The Arroyo Seco has been a consistent backdrop in John’s life. As a child he grew up exploring the Lower Arroyo helping instill in him a fascination with the natural world and a strong land ethic. As an adolescent and young adult, the Arroyo became synonymous with sports for John, including competing for school and club teams, attending world-class events at the Rose Bowl and mountain biking throughout the Angeles National Forest. 

As an adult, John and his wife, Katrina, have returned to raise their two children along the Arroyo and participate in all it has to offer.
