Jennie Salmon was named head coach of Brandeis fencing in July of 2018 after 22 years of successful club and high school coaching, as well as experience with USA Fencing.

In her second season with the Judges, Salmon qualified three fencers for the 2020 NCAA Championships, all first-year students: women's sabre fencers Jessica Morales '23 and Maggie Shealy '23, and men's epeeist Ben Rogak '23, who was selected as an alternate who was chosen to compete before the event was canceled. Morales and Shealy were named Brandeis's first All-Americans for the women since 2003. In addition, Chris Armstrong '20 was named a CoSIDA Academic All-American. 

After COVID-19 cut the 2020-21 season short, Salmon's teams had an outstanding 2021-22. Shealy and Tony Escueta '25 each competed in the sabre at the NCAA Championships at Notre Dame, with Shealy placing eighth overall for the highest finish by a Division III woman. Escueta finished 22nd. Shealy was named the United State Fencing Coaches Association National Division III Women's Sabre Fencer of the Year, while Escueta was named the National Division III Men's Sabre and Newcomer of the Year. They, along with Rogak (men's epee), Bronwyn Rothman-Hall '25 (women's epee) and Anthony Rabinkov '25 (men's sabre) all claimed Division III All-America status. 

In 2001, she co-founded the Mission Fencing Club in Rocky Point, New York, with her husband Jeff, and has been the head coach there since 2003. Her students have consistently been part of NCAA Championship teams and earned numerous All-America honors. Salmon has also coached members of the U.S. Fencing National team in all three weapons, including a 10^th-place finisher at the 2016 Cadet Women's Foil World Championships.

From 2000 through 2013, she served as head coach at Ward-Melville High School in East Setauket, New York. In her 13 seasons with the Patriots, she coached more than 60 All-Long Island fencers and 42 individual county champions across weapons and genders. At one point in her tenure, she coached WMHS to 12 consecutive undefeated League championships as her teams earned 174 straight wins, the second-longest high school sports winning streak in Long Island history. She was an eight-time Suffolk County Coach of the Year and two-time Long Island Coach of the Year.

Since 2015, Salmon has served as a regional consultant for USA Fencing, helping to build the regional tournament system for the US Fencing Association. She has also served as USA Fencing's Youth Development Chair and as a member of that organization's Tournament Oversight Committee and Athlete Handbook Revision Group. In 2015, Salmon received the USA Fencing Jack Baker Volunteer Service Award.

Collegiately, Salmon was a foil fencer and 1995 graduate of Temple University with a BA in Early Childhood, Elementary, and Special Education. A team captain in 1993 and 1994, she was a two-time foil All-American. Salmon helped the Owls to three top-three finishes among women's programs at the NCAA National Collegiate Championships, including first place in 1992. The 1992 team was inducted into the Temple Athletics Hall of Fame in October of 2021. Salmon received her MA in Literacy from Dowling College in 2002.
