June 18, 2011, Gracie Barra Seattle will host Gracie Barra black belt, Flavio "Cachorrinho" Almeida. Professor Almeida will be in town for a seminar on Saturday. The date is definite, but times are still being worked out.
If you don't know much about Flavio Almeida (other than the fact that he runs Gracie Barra and is the younger brother of recently-retired Ricardo Almeida), I've found a few nice links to help you get acquainted.
Learn a little about Flavio in this interview from the spring of 2008 with The Fightworks Podcast.
