THE LIFE & WORK OF A MAYWEATHER
Jazzy Jeff Mayweather.
FIGHTER. CHAMPION. TRAINER.
From Grand Rapids to a world title and the corners of other champions. A life in boxing, told through Jeff’s own record, words and photographs.
EXPLORE JEFF’S STORY
Before the name
became a dynasty.
Three brothers. One Michigan hometown. Boxing would become the family business.
Jeff Mayweather grew up in Grand Rapids, the youngest of the three Mayweather brothers. Floyd Mayweather Sr. and Roger had already made boxing part of the family’s life when Jeff found his own way into the sport.
Floyd Sr. became a professional welterweight and trainer. Roger became a world champion in two weight divisions. Jeff would earn a championship of his own—and, eventually, build his own career teaching fighters.
The youngest brother.
His own fighter.
Jeff began boxing training in 1983. The family archive still holds a Golden Gloves photograph: headgear on, gloves raised, another boxer in front of him.
On April 23, 1988, he made his professional debut in Las Vegas, defeating Eddie Doran on points. The youngest brother was now building a record under his own name.

A piece of the record, kept close.
The gloves came off.
The knowledge stayed.
Jeff’s place in boxing continued in the corner, on the mitts and in the daily work of preparing another fighter.
Coaching began with a friend who listened to Jeff’s advice from ringside and asked him to train him. Jeff was initially unsure. Seeing his combinations work gave him confidence as a teacher.
That fighter was David Sample. Jeff’s coaching career would later include work with world champions Sultan Ibragimov and Celestino Caballero.
“the things I was teaching were working”

It is a second body of work alongside his fighting record: helping other boxers understand what to do, then preparing them to do it under pressure.
05 / HIS OWN IDENTITY
Jazzy by name.
A teacher by practice.
The nickname began at school. Jeff recalled a teacher calling him “jazzy” because he arrived dressed in leisure suits. The name stayed with him into boxing.
Often called the “Quiet Mayweather,” Jeff has described a coaching approach that makes room for enjoyment and demands attention to defense. His mitt work asks fighters to protect themselves as well as throw punches.

Decades later,
he’s still teaching boxing.
Las Vegas is where Jeff continues to work with people on their boxing. The focus is practical: stance, footwork, combinations, defense and learning to read what is happening in front of you.
His sessions welcome beginners as well as experienced boxers. The starting point changes with the person; the knowledge comes from years spent on both sides of the ropes.
The record belongs to the past.
The teaching continues.
