Altera Executive Staff

Our exceptional staff keeps kids focused on achieving their highest aspirations, through education.

Barbara Peterson

Executive Director

Barbara Peterson’s career path has been interesting, to say the least. She has worked as a policy analyst for Interamerica studying the social service needs of migrant and seasonal farmworkers in the Yakima Valley; a bus driver (and proud member of the Amalgamated Transit Union) for Metro Transit in Seattle; a senior financial analyst at BankAmerica; an analyst of higher education policy at the Higher Education Coordinating Board; and Director of LASER (Lawyers and Students Engaged in Resolution) for the Office of the Attorney General. And that’s only a partial list. Since 1999 she has been a director, now Executive Director of ALTERA, formerly NLA Group, an educational nonprofit located in Wapato on the Yakama reservation in the Yakima Valley in Washington State.

Tiffany Coulson

Associate Director of Programming

Tiffany Coulson rarely stands still for very long. After living in five countries—the U.S. Netherlands, Iran, Austria, and Denmark— and traveling to eight more in her busy life, including Mexico, Canada, Germany, France, Jordan, England, Switzerland, and Italy, she finally settled down on a beautiful 250-acre apple orchard in Eastern Washington, where she and her husband raised four now-grown children and where the couple currently lives with a dozen goats.
