Juan Cardona, 33, is a park police officer. His jurisdiction doesnโt extend beyond downtown, but starting this fall, his influence will reach the West Side through boxing.
In April, Cardona and his family were kicked out of his son Julianโs former boxing gym. Cardona coached Julian on the side because he felt his son wasnโt receiving proper training, which led to a fallout between the family and gym.
โI told my sonโs old trainer, โYou know what? Iโm going to open up my own gym and train my fighters the right way,โโ Cardona said in reference the former gym, which he did not want to mention by name. โAfter I told him that, he said, โYeah right. Good luck with that.โโ

Last week, he opened the doors to Cardonaโs Boxing Gym.
Cardona, a father of two, worked extra shifts and held chicken plate sales to help launch the gym. He hopes to get commitments from at least 20 participants to cover the rent, but Cardona will pay out of pocket if necessary.
The dark green gym sits on the corner of Morales and North Colorado streets, on the near West Side, a 9-minute walk from the Bexar County Adult Detention Center and a 10-minute walk to Dress for Success. Cardona loves the location because it generates traffic from Tafolla Middle School and Lanier High School students. Moreover, itโs in the West Side, Cardonaโs childhood home.
โI grew up on on Martin and 19th Street,โ Cardona said. โWe didnโt have an AC, we would use the stove as a heater, but I still had a fun childhood.โ
Inside Cardonaโs Boxing Gym, six heavy bags dangle from a gold rack; against the wall to the left sits a photo of Muhammad Ali and a framed certificate of occupancy. Yellow double-end bags hang in front of the red, white and blue roped ring. The loud speed bags โ thappita, thappita, thappita, thappita โ and flags decorate the walls surrounding the ring.
Some of this equipment was sold to Cardonas at a discount from Alcoser and Gonzalez Boxing Gym on South Flores Street. The gym learned about Cardona through mutual friends; they gave him mirrors and sold him the ring.

โIโve been patient, and God blessed me with a gym and equipment,โ Cardonaย said, standing by the heavy bags. โItโsย amazing how everything has fallen into place for my whole family.โ
Cardonaโs wife, Chelsy Cardona, 31, is acting as his business coach. She is the owner of Chelsyโs Nails in Leon Valley and the sole family member with business experience.
โI never graduated from college. All I know how to do is arrest people,โ Cardona said, smiling at Chelsy, โbut my wife is the smart one.โ
She chimed in, โI help him in any way that I can because I know how tough it was when I started my business.โ
Cardona says the East Side and West Side were the only choices of locations for the gym. In neighborhoods like these, boxing gyms can become vital institutions โ vital not because of sports so much as the culture of mentoring sports can provide. Sociologists like Jeffrey O. Sacha have argued that at-risk children benefit more from mentorships than their privileged peers, and that boxing gyms are sites of mentorship.
โBeing a mentor is going to be tough, because itโs going to be my first time doing this, but Iโm hopeful,โ said Cardona, who didnโt have a mentor growing up.
Since Cardona wears a badge, he says he might be viewed in a negative light by people neighboring the gym. Growing up, he disliked law enforcement after he was harassed by a policeman โ and because a police officer killed his grandfather, he said.
More than 50,000 Hispanics reside in the 78207 zip code where Cardonaโs Boxing Gym sits. In a 2017 Pew Research survey, nearly half of Hispanics gave law enforcement a neutral or less favorable rating.
โWith social media and everything thatโs going on, cops are viewed as bad,โ Cardona said. โI want the people who come to my gym to say, โHey, not all cops are bad. My coach is a cop, and heโs always helping me out.โโ

Alongside Juan Cardona is Alex Anzures, 37, who has been around boxing for 30 years. Anzures, who also grew up on the West Side, agrees that boxingโs relationship with lower income neighborhoods is strong. Anzures plans to train at Cardonaโs gym for the rest of his days.
โIf Juan doesnโt kick me out, I plan to stay here,โ Anzures said, laughing. โThis is a perfect spot for the gym, and we plan to get some kids off the streets.โ
Anzures was working on mitts combinations with Megan Martinez, 18. Boom, boom, bap. Boom, boom, bap. Martinez grew up on the Northside, but boxed for 10 years at Zarzamora Street Gym and San Fernando Gym. Martinez, who competed in the USA Boxing Junior Olympic tournament, says boxing made her want to be something in life.
โBoxing builds confidence. (Because of boxing), things like gangs, drugs or trouble donโt even call for your attention,โ said Martinez, who plans to attend Northwest Vista College in the spring. โItโs helped me a lot and helped many others who donโt have much. Itโs a way out.โ

Eight boxers trained at Cardonaโs Gym during its opening last Wednesday. The youngest โ and lightest โ were Cardonaโs son, Julian, 11, and Eli Medrano, 9. Both have fights scheduled for Nov. 11 at Traders Village, a flea market crossed with a shopping center on the Southside. The 60-pound fighters hit every station in the gym, their shirts drenched in sweat.
Throughout the night, curious people peaked their heads into the gym to speak to Cardona.
โItโs starting to feel like a gym now,โ Cardona said, looking at others train. โIโm really excited for more people to come to our gym.โ
