## Bio

Hillary was born on the 14th of October 1988 in Arkansas, United States of America. A competitor by nature, she has been involved one way or another with numerous different sports, such as volleyball, soccer, softball, and even golf.

It was at the off season of these sports that Hillary got in touch with BJJ. Trying to find a sport that would keep her fit during the sport’s break, she started training Brazilian Jiu Jitsu at Westside MMA with two experienced coaches, Matt Hamilton and UFC’s Roli Delgado. Hillary was 18 years old, and loved her first BJJ experience (much to her mother’s dismay).

Being the competitor that she is, she immediately started competing at the local tournaments with the other girls, and sometimes even venturing in the men’s divisions. With time Hilary started her “Ronin“ training attitude, always interested in training with the best, she wondered around the US in search for as much training as possible, and also looking to go to the source of BJJ (Brazil) as often as possible.

Collecting first places in competition after competition, Hillary was awarded her Brown Belt by the hands of Roli Delgado in November 2009. In Early June 2010 Hillary achieved her Black Belt by the hands of her long term coaches Roli Delgado and Matt Hamilton. The cerimony was celebrated after she won the World Championships in the combined Brown and Black Belt Women’s Division. Being one of the very few Americans to have reached the most prestigious Jiu Jitsu tournament in the World, Hillary achieved all these amazing deeds in an astonishing time frame of little over 4 years.
