Most Improved Boxer
Adan Cazaro
🥊 Won 4 out 6 fights his first year/ probably the most awkward boxer stylistically but he makes it work

Ryan Jones aka the Cowboy 🤠
🥊 RJ had a total of 12 fights in 2022, winning 8 and losing only 4..
🥊 Gene Lewis winner
🥊 silver gloves regional champ
🥊 so cal championship finalist

Most Inspirational
Armand Calara
🥊 At age 33 he is one of the oldest fighters in the gym. He’s got bad knees and he used to get beat up by everyone. He’s earned everyone’s respect by working hard, improving and never giving up. Now, he is a beast in the ring.
🥊 he won his debut bout against an opponent 15lbs heavier.
🥊 faced Manny Pacquiao Jr in a close match.

Fighting Family
Bryan Albarran, Aris Albarran, Adan Cazaro
🥊 Bryan is the older brother or Aris and older cousin of Adan. They come to the gym EVERY DAY and put in their work. Bryan now has a winning record with 18 fights and Adan is catching up, with Aris ready to make her debut in 2023.

Coach of the Year John Hannah
🥊 even though we have many great coaches, coach John is a new addition to our staff and he has become a great asset to the team. His 7pm class is one of the most popular in the gym and he’s even managed to develop some boxers into real winners.
