Simon Redmond
OWNER/HEAD TRAINER
Originally from Dublin, Ireland, Simon Redmond has been living, boxing, and fighting competitively in San Francisco since 1996.
Simon fought and won the 1999 Golden Gloves in the Cow Palace here in San Francisco. He is a champion with a reputation of being "a hard charger, totally game, relying heavily on reach and power" (SF Bay Guardian).
In the 2001 Northern California Golden Gloves Tournament, USA Boxing awarded him the John Vidal trophy for the "most exciting bout" out of more than 70 fights.
Shortly after, he was asked to fight on the under-card of ESPN's "Friday Night Fights" in a pro-am card televised nationally from San Francisco.
The following year, Simon was unable to compete in the Golden Gloves due to immigration status issues but later fought the 2002 champion, who had a perfect 7 and 0 record, and defeated him. In 2003, with the desire to train other boxers, he cofounded 3rd St Boxing Gym. After a successful four years of teaching boxing and training fighters from all over San Francisco, Simon, with his 3rd St. Gym partner, opened Titanium Training Center in 2007 to bring on more trainers and teach a wider audience his passion.
In January 2010 he broke away from 3rd St Gym and took over Titanium Training Center and renamed and relaunched it as Polk St Gym.
Simon lives in the city with his future wife and their 2 children.
