Michael Terwilliger joined the Duke track & field coaching staff as a volunteer assistant coach in September of 2015 and works primarily with pole vault specialists and male multi-event athletes.
In 2019, Terwilliger oversaw pole vaulters Esteban Suarez and Cole Rowan, and helped lead them to personal best seasons. Suarez claimed bronze at the ACC Indoor Championships, garnering All-ACC First Team honors, while Rowan finished sixth and notched Second Team accolades at the ACC Championships. At the ACC Outdoor Championships, Rowan placed fourth and Suarez sixth, each achieving All-ACC Second Team recognition. Terwilliger also helped Rivka Arbiv and Nati Sheppard record All-ACC Second Team Indoor honors, while Sheppard claimed bronze and All-ACC First Team recognition for her third-place finish (4.12m) at the ACC Outdoor Championships.
The 2017 season saw Terwilliger assist with Daniel Golubovic, a graduate student was achieved NCAA second team All-America recognition and was named the 2017 ACC Decathlon Champion during the outdoor season.
