He attended Pennsylvania College (1864–67) and the Lutheran Theological Seminary in Philadelphia, Pennsylvania (1867–70).
He was received into the Ministerium in 1883 in Red Wing, Minnesota, and ordained in Pottstown, Pennsylvania, in 1870.
He served as a pastor in eastern Pennsylvania (1870–82), as a missionary for the Augustana Church (1882–93), and established five English language churches in the Twin Cities area, including St. John’s Lutheran.
He returned to Pennsylvania (1896–97), then went back to Minneapolis, where he joined the General Council’s Northwest Synod, and was pastor of the Salem English Lutheran Church in Minneapolis (1897–1920).
Though of German heritage, Trabert learned enough Swedish to translate at least 40 Swedish hymns into English.
He also served on the Executive Committee of the Swedish Minnesota Conference, and on the Board of Directors of Gustavus Adolphus College.
