Mark Stell, Founder

Mark Stell at the Temeke Primary School in Tanzania, just months after a solar-powered well was installed.

Mark Stell likes to travel the world in search of growers committed to high-quality coffee. He learned how to determine quality through his early career stint as a roaster and gained management and retail experience as owner of Abruzzi Coffee Roasters, a small Portland company. It wasn’t until opening Portland Roasting in 1996 that Stell was introduced to the grower component of the coffee business. Once he began his travels to coffee-producing countries, he developed a deep appreciation for the growers and their commitment and love of the land.

Mark oversees a staff of 40 and is responsible for green coffee sourcing, purchasing and financial management of the wholesale roaster and green coffee wholesale business. His leadership has earned the company local and national recognition for its business achievements and sustainability initiatives. In 2005, the company won the Specialty Coffee Association of America’s Sustainability Award for its Farm Friendly Direct™ Program, and won Roaster of the Year in 2012.

Mark also sits on several boards locally and nationally.  He founded Portland Global Initiatives in 2010 to help draw local attention to the global water crisis.
When not traveling or managing his team, he retreats with family to his cabin near Mt. Adams and tries to sneak in a fly fishing trip here and there.

Timothy J. Calderbank

From 2010 to 2012, Tim operated his own firm, Calderbank Law Offices, P.C., where he concentrated on transactional and litigation matters relating to general business, construction and real estate (both public and private matters), and hospitality. Prior to operating his own firm, Tim spent 2002-2010 as a shareholder with the law firm of Bullivant Houser Bailey, P.C., in its Portland, Oregon office, and from 1997 to 2002 as an associate attorney with the Portland office of Stoel Rives, LLP.

Tim maintains an active construction, real estate and hospitality practice providing both business advice and transactional and litigation services for private and public clients, including, but not limited to, insurance companies, general contractors, subcontractors, design professionals, developers, owners, school districts, fire protection districts, coffee roasters, restaurants, and other hospitality vendors. Tim represents these entities in matters relating to defect litigation, public and private contracting, bid disputes, dispute resolutions, licensing and registration, lien/bond claims, and general business advice.

Brandon Benson

Born and raised in Madison, Wisconsin, Brandon moved to Portland in 2001 and is currently a certified public accountant for Mack, Roberts & Company, providing tax and audit services to small businesses and their owners. A couple times in his life he’s taken some professional detours from public accounting, first obtaining a law degree from The John Marshall Law School in Chicago and later working part-time as a sports writer covering the Green Bay Packers for SB Nation. He’s also written about football for the Washington Post online.

While not a practicing attorney, Brandon volunteers monthly at the St. Andrew Legal Clinic, helping with the legal needs for low and moderate income families in the Portland area. So when Mark Stell asked Brandon to become a board member in 2010, it fit in perfectly with his interest in providing assistance to people in need, this time helping communities around the world build or repair their basic water systems.

Brandon spends his free time with his wife and three young children in SE Portland. He still keeps in touch with his friends from Wisconsin, acting as the Treasurer for the University of Wisconsin alumni chapter in Portland.
