Jeff Glover began his Brazilian Jiu-Jitsu journey under the mentorship of Ricardo "Franjinha" Miller at Paragon Academy. Displaying exceptional talent and rapid progression, Glover swiftly advanced through the ranks. On April 8, 2006, shortly before turning 23, he earned his black belt from Miller after clinching his second consecutive gold medal at the IBJJF Pan American Championship in the brown belt division. Early in his competitive career, Glover notably excelled at Grapplers Quest tournaments, frequently competing—and succeeding—in absolute (open weight) divisions, a rare feat for a featherweight competitor.

Deep Half Guard

Jeff Glover is widely credited with pioneering and popularizing the deep half guard, significantly influencing modern grappling. His innovative approach to this position transformed it into a staple technique used globally, allowing practitioners to effectively control larger opponents and initiate sweeps from seemingly disadvantageous positions.

Donkey Guard

Glover also introduced the Donkey Guard, a playful yet tactical position designed to entertain audiences and bait opponents into making mistakes. By deliberately turning his back and adopting an inverted stance, he invited opponents to engage, setting up sweeps and leg attacks. A memorable demonstration occurred at Metamoris IV (2014), where Glover effectively utilized Donkey Guard to initiate a dynamic leg attack against renowned grappler Baret Yoshida, thrilling spectators and validating the technique's effectiveness.

Jeff Glover's competition style is characterized by creativity, spontaneity, and technical brilliance.

This unique blend of flamboyance and technical mastery not only entertained audiences but also encouraged a generation of grapplers to embrace experimentation and creativity at the highest levels of competition.

In the later stages of his career, Jeff Glover transitioned into a mentorship role, informally coaching and guiding emerging American grapplers such as Kody Steele and Nathan Orchard. He consistently emphasizes enjoyment and creativity in training and competition, famously stating, "If you're not having fun, you're not going to stick with it." Glover's influence is evident whenever competitors employ innovative, inverted, or unexpected techniques, prompting commentators to remark, "That was very Jeff Glover-esque!"

Jeff Glover has publicly expressed concerns regarding contemporary Brazilian Jiu-Jitsu promotion standards, particularly criticizing the criteria used for awarding black belts.
