Instructor bios:
Monica started her martial arts journey at 15 with Taekwondo and has since studied and coached Capoeira, Muay Thai, and Brazilian Jiu Jitsu. She was introduced to BJJ in 2010 by Robby Rabadi in Austin, Texas, and earned her black belt at Fulcrum Jiu Jitsu Academy under Evan Barrett after placing 3rd at the 2024 IBJJF Master World Championship. She has also been an instructor at the BJJ Globetrotters Arizona Camp—so yes, she has probably tried to teach someone how to pull guard on a revolving door.
Monica has a background in audiology and currently teaches elementary special education. She’s a mom of four, loves working with kids, photography, and is happiest outside exploring Colorado. At Fulcrum, she handles much of the behind-the-scenes magic that keeps the academy running.
Andrea Sierra is a brown belt and the owner of New Era Jiu Jitsu. A true gi enthusiast, she will choose pajamas over spandex any day of the week and is especially known for her bow and arrow chokes. She loves sharing her passion for jiu jitsu and helping women and girls build confidence, sharpen their technique, and find their own style on the mats.
When she’s not plotting her next bow and arrow choke, Andrea loves makeup, Halloween, and basically any excuse to get creative. If there’s a way to combine jiu jitsu, a perfectly done face, and spooky season, she’s probably already thought of it.
