Joseph Macrini is in his second year as assistant track and field coach for Trinity University. He coaches the sprinters (100m, 200m, & 400m) and also the relay teams. Coach Macrini was a 2008 graduate of Trinity and was a four-year letter-winner in track and field. In addition, he has USA Track and Field Level 1 Certification.

During Coach Macrini's time at Trinity, he earned All-SCAC honors eight times. He also is the 2007 and 2008 SCAC 400-meter champion and served as team captain his senior year. Coach Macrini is currently the third fastest 400-meter runner in Trinity history and also the only two-time SCAC champion in the 400. 

Additionally, Coach Macrini competed with three other conference champions in the 4x400 relay at last year's Tiger Alumni Meet.  That event was videocast live over the internet, and was one of the most exciting events of the weekend.
