Gyms in Denver area

Looking for gyms in the Denver area. Preferably near the light rail since I'm without a car. Boxing and BJJ would be preferable, but I'll take one or the other Any recommendations?

I see a gym that's close, but it looks very froo-froo hoity toity. If anyone of you know better, hit me up. Staff listing below:

Relson Gracie BJJ isn't very far from a light rail and we have some amazing BJJ there.

High Altitude MMA - Nate Marquardt's gym, handful of other UFC fighters there and good amateurs too.
