Virginia born but Californian by heart my fitness journey started in 2008 when my fiancée and I moved across the country. I wanted to be in the best shape of my life for my upcoming wedding however, growing up a bookworm with very little desire to be athletic left me uncertain on where to start. I decided that trying group fitness classes would help give me some direction and was hooked!Leaving countless classes full of motivation and inspiration from the instructors I decided that this was something that I wanted todo. I want to show others that it doesn’t matter where you start-you just have to start. I love showing other show to challenge themselves and just how strong they are both mentally and physically. My journey started over 12 years ago, and I continue chasing my fitness and helping others meet their goals. Experiences: Athletics and Aerobic Fitness Association (AFAA) Group Fitness Instructorand Nutrition certified. Schwinn Indoor Cycle Instructor NPC Bikini Competitor trained bycurrent Ms.Fitness Olympia Whitney Jones Crossfit and Olympic Lifting trained by one of the worlds top athletes Chyna Cho. These experiences have opened doors to allow me to become a MuscleEgg sponsored athlete and a BSN/Optimum Nutrition regional demo representative during my competing years. I’m also owner of Wanderlust Studio AZ and have done hair and makeup for tons of events andphotoshoots. Fun! You can find me training Brazilian Jiu Jitsu (current obsession!), teaching our exciting FitMethod classes here at Ares East MesaBJJ or doing a little hair and makeup on occasion!


Colin Opper
I was born on the mean street of Eau Claire, Wisconsin. I started wrestling at the age of 5 and competed in folkstyle, freestyle and Greco-Roman style wrestling for the next 13 years. After passing on wrestling in college, I moved to the Milwaukee area for college. In 2006, a co-worker invited me to an open mat at the BJJ academy he trained at and I was hooked after one class. I began training under Henry Matamoros who would eventually become Wisconsin’s first Brazilian jiu-jitsu black belt under Pedro Sauer. After taking a couple years off to focus on my rugby career, I started training BJJ again under Eric “Red” Schafer, another Pedro Sauer black belt. There I was promoted to purple belt. Life then brought me to Mesa, Arizona. After taking a couple years off to get my family situated in the desert, I began training again at Ares East Mesa BJJ. I earned my brown belt in 2022. I have competed all over the country with notable wins in Submission Hunter, Wanderlust Grappling, and Fight2Win. As a coach, I like to create an environment that allows creativity and engagement from everyone on the mats.
