When Dirk Hafemeister was 30-years-old, he won the gold medal with the West German show jumping team at the 1988 Seoul Olympics, while in the individual event he finished 19th with his horse Orchidee. His second major event was the 1994 World Equestrian Games at Den Haag, when he again claimed a team gold medal, this time with PS Priamos. He also won five West German team championships and was on the podium twice individually (silver in 1988 and bronze in 1991).
After his active career Hafemeister was engaged as a riding coach for show jumpers. He was born in Berlin as the son of a construction entrepreneur. Hafemeister was a close friend of Paul Schöckemöhle and started his riding career in Schöckemöhle’s stable where Hafemeister trained horses.
