Start-up experience

Before law school, Pete served on the management team of a fledgling San Francisco company that collected used kitchen oil for biodiesel conversion. He deeply was involved with all aspects of the business, from personally running service routes and repairing equipment, to sales, to managing finances. This greasy experience gave Pete valuable insight into the myriad challenges of running a business, and informs his practical, client-focused approach to practicing law.

Scout's honor

A second-generation Eagle Scout, Pete spent his youth heavily involved with scouting. He remains a strong advocate for the scouting program.

An environmental lawyer at heart

Pete’s interest in environmental law stems from a lifelong love of the outdoors. He has camped, backpacked, fished, and built trails throughout the country, and is generally happiest with a pack on his back, a fly rod in his hand, or a tent over his head.
