Keijo Koivumäki competed most of his career with his older brother Eero and together they became the top Finnish double scullers at the start of 1950s.

He was the general secretary of the Finnish Rowing Federation from 1955-57 and 1960-66 and was treasurer of the Finnish Rowing Federation from 1948-51 and again beginning in 2001. He was also chief editor of Airo Lehti, a monthly Finnish rowing magazine, in 1960.
