DMG Boxing proudly welcomes Samuel “S3” Arnold III, one of the most promising young middleweights in the sport today. At just 22 years old, the undefeated Dallas native is already making waves with a perfect 14-0 record, including 9 explosive knockouts. Standing tall at 6’3”, Arnold combines reach, ring IQ, and a slick, composed style that has quickly set him apart as a true rising star.

Turning pro at 17, Arnold’s fast ascent is no accident—his sharp technique, discipline, and highlight-reel finishes speak for themselves. Now under the DMG banner, he’s poised to reach new heights.
