A three-time honorable mention All-American, DeMoulin helped changed the landscape of the diving program at Geneseo. Prior to his arrival, Geneseo had just five All-American certificates on the diving board in nearly 50 years of competition, including two by fellow Geneseo Sports Hall of Famer, Randy Shepard. A native of Pittsford, New York and graduate of Pittsford Mendon High School, DeMoulin's transformation over four years was remarkable as he progressed from not making the finals as a first year to earning the SUNYAC Championship on both the one and three meter boards as a senior in 2011. His three national awards came in three consecutive years, on the low board in 2009 and 2010 and on the high board in 2011. A four-time SUNYAC team champion, Geneseo posted an unblemished 43-0 dual meet record in his four seasons and his career culminated with the 2011 Ira S. Wilson Award as Geneseo's top male athlete.
