She began a professional career singing and broadcasting at the Canadian Broadcasting Corporation (CBC), and continued for three more years as a writer and on-air personality for the English Language Service of Radio Ethiopia. Eventually, she began a career in classical music and in opera. She met her future husband, David troup, singing in a production of Franz Lehar's THE MERRY WIDOW. They formed the "Singing Team of David & Dorothy" that performed for many years both throughout the USA, and onboard luxury cruise liners around the world.

Dorothy has sung in churches since she was a young girl of ten years, gradually moving into the professional sphere. Here in the Washington, DC area, she sang as a choir member and soprano soloist at Chevy Chase United Methodist Church, the Shrine of the Immaculate Conception, the Church of the Annunciation, Fourth Presbyterian Church, and Calvary Hill Baptist. Each Fall, for the past eleven years, Dorothy has also sung in the High Holy Days Services at Temple Rodef Shalom. Ecumenicism is definitely her watchword!

She is currently a candidate for a Master's Degree at the John Leland Center and serves as the Ministry Intern at Calvary Hill Baptist. David and Dorothy have two adult daughters and five grandchildren. She and David reside in Fairfax, and teach voice lessons privately. They love their Shetland Sheepdogs as well as their forested garden.
