I have gotten to meet so many amazing people through the academy. If you are looking for an academy to train at while visiting a new area check these out.
http://curucuruland.com/ Professor Rodrigo Pagani runs an amazing Jiu Jitsu academy / hostel just outside of Rio de Janerio in Niteroi, Brazil. I've had the good fortune to go and train there four times so far, and I simply can't get enough. Rodrigo is one of the most passionate, knowledgeable people about Jiu Jitsu that I've ever had the pleasure to meet and train with. Curu Curu Land is a very special place.
https://juberajj.com/ Matt Jubera runs an amazing academy out in Denver, Colorado. He is one of the brightest minds in the sport I know (literally he's an encyclopedia of technique and concepts) and we have been collaborating on academy ideas since 2010.
