Coach Mallory Souliotis brings passion, experience, and a winning pedigree to the Concord-Carlisle Patriots bench. During high school at Noble and Greenough School, Mallory was on the defensive line helping her team to 4-consecutive ISL Championships, 2 New England Class A Championships, and was named to the NEPSAC Class A Second All-Star Team her senior year. From 2014-2018, she played at Yale University, scoring 70 points in 117 NCAA games. In her rookie season, she earned 9 points in 26 games and was named most improved player. The next year, she led the team with 25 points in 29 games and had the third-highest single-season assist total in Yale history. In her senior year, she was the top-scoring defender in the Ivy League with 24 points in 31 games, earning First Team All-Ivy and Third Team All-ECAC honors.

Coach Souliotis was drafted 8th overall by the Boston Pride in 2017 and signed her first contract on March 1, 2018.  She played in two games that season and the playoffs. In her first full season, she scored 6 points in 14 games, ranking in the top 10 for plus/ minus, and scored her first goal in December 2018. In her second full NWHL season, she scored a career-high 16 points in 22 games, ranking fifth among defenders, as the Pride nearly went undefeated and reached the Isobel Cup finals before the final was canceled due to COVID-19.
