His teams reached the MAWPC championship game four times between 2017 and 2025 and added four third-place finishes, keeping GW among the league's top programs.

The 2017 squad also posted a notable breakthrough season, winning three games in three days to claim the MAWPC title and finishing with a No. 17 ranking.
