Pierre Pasche played for the Black Boys Hockey Club in Genève for over a decade, starting in the 1930s. This also included a stint where he was its coach in the early 1940s. His field hockey career saw him be selected multiple times for the national team, which included a selection to the 1948 Swiss Olympic team to compete in London. The Swiss team finished with one win and two ties, but ultimately did not accumulate enough points to advance past the preliminary round. He retired shortly after, but remained active as a referee/official.
