Juancarlos "JC" Nunez is the head coach of the University of Massachusetts Amherst women's tennis program in Amherst, Massachusetts, a position he has held since June 8, 2017. The 2026-27 year marks his 10th season as head coach and his 16th overall season on the UMass coaching staff after an earlier six-year stint as an assistant.
Nunez took over the program after longtime head coach Judy Dixon retired following the 2016-17 season. Through eight completed seasons as head coach, he compiled a 104-54 overall record and a 36-6 mark in conference play, first in the Atlantic 10 and then in the Mid-American Conference. His teams reached eight conference tournaments during that span, including six appearances in the A-10 era.
