Even though Kalvin had turned into a NWA resident (and in that time became a 4x state champ) he still made sure to tear up the boxing game anywhere he could, including his home state. He was a Gold Medalist at the 2010 Texas Games, received Silver in 2011, and is a Fort Worth Regional Golden Gloves Champion. While on a national scale he represented Team USA as a middleweight fighter in the World Series of Boxing.
Kalvin began his pro boxing career in 2016 and has only continued to grow. Since 2016 he has been named the NAMA Middleweight Champion, the UBF Intercontinental Super Middleweight Champion, and was the recipient of the 2018 Bennie Briscoe Philly Fight of the Year award. Not surprising considering his current record stands at 12 wins, 0 losses, and 8 knockouts. 2 of those wins were against previously undefeated fighters until Kalvin hit em with the sauce that is.
