[2] He studied Chinese for one year, then accepted a post as a professor of education at Cheeloo University in Jinan, Shandong province.
[3] In his first year, Garside assisted eleven Christian colleges in China in reopening after they had shut down due to political turmoil within the Kuomintang (KMT).
[3] At the ABCCC, Garside led efforts to promote and raise money to support these colleges, which in the 1932–1933 academic year had combined enrollments of 5,400 students and endowments of US$12 million.
Garside joined the movement in the United States to raise awareness of the war and encourage other Americans to boycott Japanese goods.
[11][1][12] The new board for this organization included Pearl Buck, William Bullitt, Henry Luce, Robert Sproul, Wendell Willkie, John D. Rockefeller III, Theodore Roosevelt Jr., David O. Selznick, and Thomas Lamont.
This board appointed Garside as the executive director, and he set out to raise the money needed to help the refugees from the war.
The organization, which was renamed United Service to China (USC) after the Second World War, raised over US$50 million in donations over ten years.
[11][1][14] Garside's skill in fundraising was shown by the receipt of over $500,000 by June 1941, a mere three months after the launch of the original campaign seeking $5,000,000.
Garside was appointed as the executive director of the American Bureau for Medical Aid to China (ABMAC), and remained in that post until his retirement in 1979.
