Bob came to his alma mater in 1983 to become the Director of Cross Country and Track & Field. During his 17 years as head coach, he impressed Brown with his dedication to student-athletes, his knowledge of the sport, and his high energy level. The excitement was never more evident than in 1992 when Rothenberg led the women's indoor track and field squad to its first Heptagonal Championship in the team's 40-year history. Since that first Heps title, the women's track and field team has gone on to capture 9 more Heps titles, winning indoors and outdoors in 1993, 1994 and 1999, and outdoors in 1996, 1998 and 2000. The cross country team also won the Heps title in 1999 and finished ninth at the NCAAs.
In addition to leading the women's track and field team to ten Heptagonal Championships, Rothenberg has directed the men's cross country team to NCAA appearances in 1987, 1992, and 1996. The Bears finished ninth in the nation in 1987, 13th in 1992 and 18th in 1996.
In his tenure, Rothenberg saw more than 100 school records set by his men's and women's track and field teams, and his men's and women's cross country and track and field athletes enjoyed numerous individual honors. From 1985 to 2000, Brown athletes participated in 10 of 15 NCAA Cross Country Championships, 11 of 16 NCAA indoor Track and Field Championships and 14 of 16 NCAA Outdoor Track and Field Championships. In 1989, Rothenberg coached Greg Whiteley '89 to an NCAA title in the 3,000 meters, which was Brown's first individual NCAA track and field title since 1952 and only third ever.
Rothenberg's had athletes earn All-American status, set the course record at Van Cortlandt Park and break four minutes in the mile. Many of them are still competing, which Rothenberg feels is a sign of the love for running that is so much a part of the Brown program. He continues to coach one of those post-collegiate athletes. Trinity Gray '00 finished the 2000 outdoor season with the two fastest 800 performances of any U.S. runner, 1:45.10 and 1:44.91, then followed it with the fastest 800 in 2001 (1:44.56).
Rothenberg received both his bachelor of arts in history (1965) and his master's degree in teaching (1966) from Brown. While an undergraduate student, he won three letters in both track and cross country and served as co-captain of the cross country team his senior year. During his graduate study program, he served as a part-time assistant coach under Brown track mentor Ivan Fuqua.
After teaching and coaching at Glen Ridge (NJ) High School, Rothenberg served in the Peace Corps for two years. Upon his return, he coached at Fairmont Heights High School in Chapel Oaks, Maryland for 12 years and then at neighboring Suitland High School for two years. His team compiled 18 state team titles, 47 individual titles, and 33 state relay titles. Rothenberg has always been active in all areas of track and field and will serve as meet director for Brown's high school cross country and indoor track and field meets. He will also manage the National Scholastic Indoor Championships and co-direct the newly created Armory Collegiate meet in 2001.
Rothenberg and his wife, Anne, Brown's jumps and multis coach, reside in Exeter. They have two sons, Jason and Brian. A civic minded individual, Rothenberg is a strong supporter of Special Olympics in Rhode Island, and has been involved in numerous volunteer projects.
