Chemotti did what no other coach in the history of Division I lacrosse was able to accomplish; he took a first-year program to the NCAA Tournament in 2014. He followed that by taking the Spiders to an undefeated league season in the newly-formed Southern Conference in 2015, and has led the Spiders to their respective conference championship games every year of the program’s existance.

After helping lead the Loyola University Maryland men's lacrosse team as offensive coordinator to the 2012 Division I National Championship in 2012, Chemotti was named head coach of the Richmond men's lacrosse team in October of 2012. He spent that school year recruiting and putting in place the tenets of the program which began play in the 2014 season, and it led to the young squad earning an Atlantic Sun Conference championship and berth into the newly-expanded NCAA Tournament.

2017 was a historic season for the Spiders, posting a program record 12 victories and reaching as high as No. 11 in the national polls. For the second straight year, Richmond knocked off a national power, taking down defending national champion UNC, 6-5, in Chapel Hill. In addition, two Spiders earned First Team All-American honors for the first time when Brendan Hynes and Benny Pugh were recognized. Pugh and Hynes also became the first Spiders to ever be drafted into the professional ranks, both being drafted in the Major League Lacrosse draft.

The Spiders saw success again in 2016, their second season in the Southern Conference, posting an 11-5 overall record and a 6-1 mark in conference play. After jumping out to a 4-1 start, the Spiders logged the biggest win in program history, taking down No. 9 Duke on the road, 12-10. The win and another victory over Jacksonville would give the 6-1 Spiders the best start in program history, propelling the team to a No. 18 ranking, the highest in program history. Shortly after, Mitch Goldberg was named to the prestigious Tewaaraton Award Watch List. The team finished third nationally in scoring defense, allowing just 7.44 goals per game, and first in caused turnovers and clearing percentag for the second year in a row. Junior Brendan Hynes ranked second in the nation in caused turnovers, while junior Ryan Dennis ranked ninth nationally in the same category. Seven Spiders earned postseason honors, led by Hynes and senior Alex Hatem, who were named to the SoCon First Team.
