ABSN partnered with Bethel Community Services Association, YKHC’s Yuut Elitnaurviat Learning Center and AVCP Housing Authority to provide ABSN’s 16 hour boiler training course to 7 rural maintenance staff. Charlie deer’s training hours were covered by $2,100 in matching funds from ABSN. AEA VEUEEM grant funds were used to cover air fair and lodging in Bethel for the following maintenance staff from this grant’s villages: Chefornak: Bernard Mael, Kongiganak: John Phillip, Kwigillingok: Benedict White, Mekoryuk: Alvin David, Quinhagak: Norman Cleveland and Adolph Pleasant. Andrew Lind of Port Heiden (NW-SW Region VEUEEM grant) was also brought to Bethel for this class.
