Kalin was named the fourth head coach in program history in March 2019, taking over for former coach Keith Moser, who held the title for 29 seasons.
In just his first season at the helm for the Saints, he reached several milestones. With a 10-10-1 overall record, Marymount earned its first 10-win season in program history dating back to 1987. The .500 record was also the best record since 2010 when the Saints went 8-8-3. In Atlantic East play, they went 4-2 in the regular season, the first winning record in league competition since 1999 in the Capital Athletic Conference. The Saints advanced to the semifinals of the Atlantic East tournament before falling in penalty kicks to Immaculata University. For the first time in program history, the Saints earned a bid to the ECAC DIII tournament. The team had three players earn spots on All-Conference including Rodney Ngoh, Ridwaan Robinson and Carlos Varona. Additionally, the Marymount coaching staff was named the Atlantic East Coaching Staff of the Year. More awards came in later, with Ngoh earning a spot on Second-Team All-ECAC and Robinson earning a spot on VaSID All-State.
Bringing 11 years of collegiate coaching experience, including 10 years as a head coach at Division III, Kalin has a decorated background in men's soccer. His most recently role was at the University of Albany as the first assistant on the nationally-ranked men's soccer team. While he was there, he mentored a squad that went to the America East Championship for the second-straight season and advanced to the second round of the NCAA tournament, defeating Maryland in the first round.
Prior to his arrival at Albany, he spent one season in 2016 at The College of New Rochelle in New York for the inaugural season of the men's soccer team. In just four months, Kalin recruited a team of 15 freshmen that set a NCAA best record of 16-3 in a first-year program. The team led Division III that season in scoring with 4.3 goals per game, while coaching a freshman that led the country in scoring before being named ECAC Player of the Year and AD3I National Player of the Year. A record first season also had Kalin named AD3I National Coach of the Year.
The rest of his coaching career was in the Skyline Conference, working with the College of Mount Saint Vincent from 2013-15 and New York University – Polytechnic Institute from 2007-13.
In his first season with MSV, he turned a team that went 2-10-1 in 2012 to 12-5-2 in his first season in 2013, the second-best single-season turnover in NCAA Division III. In his three years with the Dolphins, he posted 33 wins while advancing to the Skyline playoffs in two of the seasons.
His longest tenure at a school was his first head coaching job at Polytech, guiding the program for six seasons, again turning around a struggling history to become a regional contender. He advanced the team to the Skyline playoffs in three of his last four seasons, while posted a program-best mark of 12-5-2 in 2010. He was also named Skyline Coach of the Year in 2009.
Beyond his coaching experience, he was also on several committees for the NCAA including be on the Regional Advisory Committee for six years and on the Soccer Rules Committee for the past three years.
