In his four years at the helm of the Ohio field hockey program, head coach Neil Macmillan has led the Bobcats to a better record in conference play than any other Mid-American Conference school during that span (29-11). He led the 2008 Bobcats to their third-straight MAC Tournament title game, an above .500 record in league play for a fourth-straight year and became the second-fastest Bobcat coach to collect 50 wins with a victory over Miami in the MAC Tournament Semifinals Nov. 7. In 2007, he and his staff led the Bobcats to the school's second-best overall record (18-5), tied the best conference record of all time (9-1), won a MAC regular season and Tournament championship for a second-straight year and earned an NCAA Tournament birth. Under Macmillan, Ohio has garnered 10 All-MAC First Team selections, eight All-MAC Second Team selections and a MAC Player of the Year in 2005 and 2007.

A coach and player of national distinction, Macmillan, a native of England, was named 2007 NFHCA West Region Coach of the Year and the 2006 MAC Coach of the Year after winning the MAC regular season and Tournament. He was also selected to coach in the 2007 NFHCA All-Star Game.

Before Ohio, Macmillan made an immediate impact at Wake Forest, helping guide the Demon Deacons to three consecutive NCAA Championships (2002-04), two Atlantic Coast Conference regular-season and tournament titles, four second-place ACC regular-season finishes and a record of 114-19 from 1999 through 2004. In Macmillan's six seasons in Winston-Salem, the Demon Deacons advanced to the Final Four five times. While at Wake Forest, Macmillan aided in scouting opponents, planning practices and developing game strategies. He also served as the recruiting coordinator and helped sign the 2004 National Field Hockey Player of the Year, five USA National Team members and numerous All-Americans. Other duties included organizing travel arrangements and monitoring the team's academic progress.

Since coming to the United States, Macmillan has also played an active roll in the United States Field Hockey Association. In the two years prior to his appointment at Ohio, Macmillan coached at B-Camp; a developmental program for athletes ages 15-19. In 2004, Macmillan was also selected as an assistant coach to the Under-16 U.S. National Team and was an assistant and head coach for a USFHA Summer League team, Southern Charm, from 2001-04. In June 2007 he coached at FDIC, which is an invitational camp for the country's elite high school players.

In 2004, Macmillan served as head coach of the Montreal Dita indoor team, which played in the North America Premier League. He has also been a mainstay on the staff at the Jennifer Averill Field Hockey Camp and helped at the UNC camp.

Prior to his coaching career in the United States, Macmillan was part of the Havant Hockey Club for 10 years, winning the National League Division One Championship in 1990 and 1991, the European Cup in 1990 and participating in the European Cup championships the following two years. Macmillan then played for the Beeston Hockey Club in the English National League at the Division One level as a goalkeeper.

While completing his studies in engineering at Loughborough University, he led the Loughborough's Students' Hockey Club to the 1995 British Universities first XI Championship and a runner-up finish in 1996. Upon completion of his degree, Macmillan was a member of the St. Albans Hockey Club in the English National League, until coming to the U.S. to be a part of the Demon Deacons' field hockey program.

Macmillan is a member of the National Field Hockey Coaches Association and United States Field Hockey Association.
