Who Is Jenna Williams? Meet RUF 66's Main Event Fighter

When Jenna Williams steps into the cage at Celebrity Theatre this Saturday night, she'll carry an unblemished 2-0 professional record and the weight of main event expectations. The Phoenix-based flyweight has quickly emerged as one of Arizona's most promising female fighters, and RUF 66 represents her biggest test yet: a showdown with veteran Ashley Deen that could catapult her career to the next level.

From Tucson to the MMA Lab

Born in Tucson, Arizona, Williams relocated to Phoenix to pursue her MMA career and train at one of the sport's most respected gyms—The MMA Lab. The Glendale-based facility has produced a long list of UFC talent, and Williams has absorbed the high-level training environment while developing her own identity as a fighter.

Williams built her foundation through a competitive amateur career, compiling a 5-4 record while competing across multiple weight classes. Those nine fights provided invaluable cage time and helped her refine the skills she'd need at the professional level.

Professional Career

Williams made her professional debut on February 28, 2025, at Fierce FC 38 in Salt Lake City. Facing Tyler Schaefer, she showed the poise of a veteran, earning a split decision victory over three rounds. The close scorecards reflected a competitive fight, but Williams demonstrated she belonged at the professional level.

Her second pro bout came at Rumble at the Roseland 128 in Portland, Oregon, where she headlined the event in a bantamweight contest. Another decision win extended her record to 2-0 and established her as a fighter promoters want to feature.

"Williams' aggressive style and finishing instincts make her an exciting addition to the women's flyweight division."

Fighting Style

Training at The MMA Lab has given Williams access to world-class instruction in all areas of mixed martial arts. Her game reflects that well-rounded development—she's comfortable on the feet and dangerous in grappling exchanges. Her amateur career included submission victories that demonstrated her finishing instincts when fights hit the mat.

At 5'5" with a 65-inch reach, Williams has solid physical tools for the flyweight division. She uses her length to establish range on the feet while staying active enough to avoid being picked apart from distance.

The RUF 66 Challenge

Saturday's main event against Ashley Deen represents a significant step up in competition. Deen brings an 8-7 professional record and the kind of experience that can only be earned through years of high-level fights. For Williams, it's an opportunity to prove her 2-0 start wasn't a fluke—that she's ready for the challenges that come with headlining events.

The 125-pound bout will be contested over three five-minute rounds, giving both women time to implement their game plans and test each other's cardio. Williams will need to blend her technical training with the fight IQ to handle a veteran who's seen every situation inside the cage.

Beyond the Cage

Outside of fighting, Williams works as a certified personal trainer at Lifetime Fitness in Scottsdale, helping others pursue their fitness goals while she chases her own dreams in the cage. Her dedication to health and fitness extends beyond her own training—it's a lifestyle she shares with her community.

Williams has built a strong following on social media, with over 36,000 followers on Instagram where she documents her training, fight preparations, and personal life. That platform has helped her connect with fans and build the kind of profile that could open doors as her career progresses.

What to Watch For at RUF 66

When Williams and Deen meet in the main event, watch for Williams to use her reach and movement to control distance early. Her MMA Lab training emphasizes technical striking, so she'll likely look to establish her jab and set up combinations.

If the fight goes to the ground, Williams has shown she can threaten submissions. Deen's experience makes her dangerous in scrambles, so Williams will need to be smart about her shot selection and ground control.

The biggest question is how Williams handles the pressure of her first main event against a seasoned opponent. If she can stay composed and fight her fight, she has the tools to extend her undefeated record and announce herself as a serious prospect in women's MMA.
