The NFL currently has one female strength and conditioning coach listed on any of their teams’ websites, and that is Raiders coach Kelsey Martinez, who is already impressing in her time with the team.

Coach Jon Gruden called Martinez “spectacular” at the annual league meeting in Orlando earlier this offseason and added a “wait ’till you meet her” to cap his glowing comments on the former Colorado State University product.

Though Martinez is the only current female strength and conditioning coach in the league, the 49ers did hire Katie Sowers as an offensive assistant in 2017 one season after the Bills hired Kathryn Smith as the team’s full-time special teams quality control coach. Martinez is also not the first female to serve in her role in league history, as that distinction belongs to Lee Brandon, who joined the Jets’ coaching staff in 1990.

“She has the blessing of being in there under a great head strength coach. She has the opportunity to learn from some of the best in the industry . . . Great mentors were truly, at the end of the day, in any career, the thing that set us all apart,” Brandon said to the Mercury News’ Matthew Schneidman Tuesday.

Martinez spent the last two years at Tom Shaw Performance, where she worked with baseball, softball, women’s tennis and track and field athletes. She has also assisted with the NFL Combine and NFL Veteran Training Programs and played collegiate softball at Bethany College, according to the team’s official website.
