Jessica is currently a Youth Black Belt in Shotokan Karate,  Youth Orange Belt in Brazilian Jiu-Jitsu, a Brazilian Jiu-Jitsu youth instructor and an honor roll student at her school. In 2017 Jessica created the “Little Monster Challenge”, a yearlong fundraiser for St. Jude linking her passion for Brazilian jiu-jitsu and karate competitions with a great cause raising over $2000.00 in donations and pledges.

Her competitive ferocity has earned her the enduring nickname “Little Monster” from her sensei and coaches as they comment that she is always up for the challenge. In her competing division, she is currently the three-time USKA Arizona State Champion, three-time Southwest Regional Kumite Champion, three-time AZSBJJF Arizona State Brazilian Jiu-Jitsu Champion, two-time IBJJF Brazilian Jiu-Jitsu US National Champion and IBJJF Kids Pan Am Champion.
