I've trained at almost all of the gyms in town. There are a ton of great options. I train at Sergio Penha's. I find Sergio's technique to be far above everyone else in town. I also feel like we have the most family and friendly atmosphere that still trains really hard. Sergios' worked with everyone from Sakuraba, Mir, Galvao, Jacare and a ton more. Come by for a week and check it out.
Steve Cantwell (WEC champ and UFC vet) is a Sergio blackbelt that teaches at One Kick's Gym. Best kickboxing in town. Steve's a great teacher too.
If I didn't train with Sergio I'd probably be with Sim at CK. Sim's got a beautiful game and is an excellent teacher, probably one of the most underated in the country.
I got to hang out with Robert Follis at Randy's and was extremely impressed with is teaching. Very cool guy and co-founder of Team Quest.
Fredson and Vinny are at Syndicate. Vinny is 10planet and Fredson is a badass, just be aware that he rolls hard, with everyone haha.
I only trained at Drysdale's once and have never been to Mica's so i can't say what they're really like. I think Abmar is teaching at Robert's.
Wand's place is cool but more of an MMA school. He's a super nice guy and very welcoming. I belive Demente is teaching there now.
Rodrigo Botti is a Leo Viera guy and is at The Pitt. Cool guy but I've never taken a class with him. Just hung out with him a bit when we interviewed Leo.
