Thomas Monahan truly encapsulates what it means to be a Corsair. He played number one his entire career as a member of the Southeastern Massachusetts University men's tennis team from 1970-74. In 1971, he led what is perhaps the greatest team ever at UMass Dartmouth. The team qualified for the NAIA Championship Tournament in Kansas City and finished the year as the no. 12 team in the nation. Monahan achieved an in individual record of 33 wins and 1 loss.

As the number one player in his sophomore and junior years, Monahan was the runner-up in district singles and won the doubles championship with fellow Hall of Famer, Roger Canto, who was inducted in 1997.

Monahan's team won the district championship in 1974 to return to the NAIA National Tournament in his senior season. At that same time, Monahan faced economic hardship and was forced to leave the university without finishing his degree. His tennis skills led him to become a professional where he has played all around the country, represented the United States in the Osuna Cup, and was named the New England Tennis Pro of the Year in 1980. This led Monahan to become the Tennis Director at the Denver Country Club in Colorado. He later moved to California to become a financial advisor for firms such as Dean Witter, Morgan Stanley and Wells Fargo.

At the age of 66, Monahan returned to UMass Dartmouth in 2018 to finish his degree and participated in his graduation with his classmates in 2020. He is currently continuing his education at his alma mater, pursuing his master's degree in public policy, he is set to graduate in the spring of 2022.
