Plotkin joined Riley's staff at Notre Dame after spending the previous two seasons as a Dartmouth assistant coach. He was on the Big Green staff for each of the past two Ivy League championships during Dartmouth’s conference four-peat, which included a 12-3-1 mark and the 15th overall seed in the 2017 NCAA Division I Men’s Soccer Championship.
In two seasons under Plotkin’s guidance, Dartmouth’s Wyatt Omsberg earned a pair of United Soccer Coaches All-America citations and doubled as the Ivy League Defensive Player of the Year. More than 13 players, including Omsberg, received All-Ivy recognition during that span, and the Big Green earned a 2016 NSCAA Team Academic Award in honor of strong performance in the classroom.
Prior to his time at Dartmouth, Plotkin was an assistant coach at Loyola University (Chicago) for three seasons from 2013-15. The Ramblers swept Missouri Valley Conference Player, Defensive Player and Goalkeeper of the Year awards during the 2015 campaign, while leading the NCAA in both team goals against average and the fewest goals allowed that season. A total of 12 players recruited under Plotkin’s watch ultimately achieved all-conference plaudits, and the Loyola staff received Missouri Valley Conference Coaching Staff of the Year honors in 2014.
Plotkin got his start in coaching with both Sockers FC Chicago and the Chicago Fire youth academy, which both compete in high-level soccer events across the Midwest and United States each season. Plotkin first broke into coaching during a professional career that saw stops with both the Chicago Fire and Columbus Crew of MLS, and the Carolina Railhawks of the North American Soccer League (NASL). Plotkin played for the 2006 United States Open Cup champion Chicago, and later won an MLS Cup title with Columbus in 2008.
A standout player at Indiana University from 2002-05, Plotkin was an integral part of two national championship Hoosier sides in both 2003 and 2004. He was named the 2005 Big Ten Conference Player of the Year, was a runner-up for the 2005 MAC Hermann Trophy and was an Academic All-Big Ten choice in both 2003 and 2004.
Plotkin graduated from the College of Arts and Science at Indiana with a degree in general studies/communications. He holds a United Soccer Coaches (NSCAA) Premier Diploma and a USSF National “B” License.
