I have always had a competitive nature having had an amateur athletic background in high school football, wrestling (for one year), as well as track. I was fortunate to have gone to West Aurora High School where athletics were paramount. As a consequence, I~SQ~ve participated in a course called athletic physical education for all 4 years of high school where power lifting and Olympic weight training were the premise of our PE classes as opposed to the regular gym classes. Things fell off while I went through undergrad and graduate school for healthcare and I discovered CrossFit at an integral period of my life. Despite consistent workouts, my nutrition was not the greatest and I believe my weight at my heaviest was 327 lbs. Discovering CrossFit reignited my competitive fervor having had an athletic background and it also enforces my genuine desire for maintaining a fit lifestyle. I found the CrossFit methodology to be supreme to maintain health and fitness. I enjoy tracking my workouts to ensure that I progressively overload and improve my physical fitness whether it is more weight on the bar or improved times from repeated HERO and benchmark workouts. After practicing CrossFit for 7 years, I~SQ~ve decided to pursue coaching as a new challenge to help facilitate others in navigating their fitness journey and attaining the fitness goals that athletes have set for themselves.</td></table>"))

The combination of intensity, community, and functional fitness was what had been missing. It turns out that you get way more fit doing burpees than paying for a globo gym membership that you never use. <br> <br>From that moment on, I~SQ~ve thrown myself into CrossFit WODs with the same energy and enthusiasm once reserved for 5 a.m. swim practice, trading my cap for barbells, chalk, and much more yelling (encouraging yelling, naturally). <br> <br>As a coach, I offer a unique blend of athletic experience, coaching enthusiasm, and a healthy sense of humor to the gym floor. If you’re chasing a new PR, learning a new movement skill or just trying to remember how to breathe during a WOD, I~SQ~m here to guide, motivate, and occasionally entertain—with a coaching style that’s supportive, technical, and just the right amount of sarcastic.</td></table>"))

At that time, I was set on playing football next season and I needed to get into better shape. I always was strong for my size as I would lift at my house, but I never reached a good physique. As I kept training, I realized CrossFit not only helped my strength but also furthered my cardio, speed, flexibility, and much more. I came to the conclusion that football was not in my future (as I~SQ~m about 5~SQ~8 and 155 lbs). So, I decided to stick with CrossFit. I~SQ~m over 5 years in and I~SQ~m in the best shape of my life at only 20 years old. I know with being a coach it~SQ~ll make me push myself harder every week. I can~SQ~t wait to see where my physical journey goes, and I can~SQ~t wait to help others around me. I love to joke around and have fun with the community and I~SQ~m super excited to talk with a bunch of new people during my classes. CrossFit has taught me how to be ~SQ~comfortable with the uncomfortable~SQ~. <br> <br>Other than working out, I absolutely love football (sadly I~SQ~m a bears fan), movies, tv shows, playing cards/videogames, fishing, and spending time with family.</td></table>"))

Having been a personal trainer, I Had heard of CrossFit, but never really paid much attention to it. During that Games, one of the events was the “Burden Run”, and after watching these athletes complete such a daunting workout, I decided that I wanted to be capable of it. <br> <br>Funnily enough, I didn’t grow up playing sports or being competitive in any way. When I got to college, I started to work out by following traditional bodybuilding-style programs that ran 8-12 weeks. Every time I began a new program, I would get bored in the first few weeks and start researching some changes to make. After seeking out CrossFit in 2014 I put on muscle, became much stronger, and actually began feeling less joint pain and issues that I had from muscular imbalances. It just worked for me. <br> <br>I truly believe that CrossFit methodology can and does work for everyone, and leads people to a mindset of focusing on their performance over a number on the scale. That same year, I took the plunge and got my L1, started coaching, and never looked back. I got my L2 the following year, and then passed my L3 exam in 2019. I love coaching people to find their best selves and live their best lives by showing them that they are capable of things they may have never thought possible.</td></table>"))

Sports like gymnastics, horseback riding, and track fueled my drive to push boundaries and achieve more. <br> <br>Even through college and beyond, my love for fitness never faded. But traditional gym routines left me uninspired—until my husband encouraged me to try CrossFit. What started as a leap of faith turned into a life-changing passion. <br> <br>Despite initial nerves, I embraced the challenge. The intensity, variety, and community of CrossFit reignited my motivation and pushed me to grow both as an athlete and as a coach. I went on to earn my CrossFit Level 3 Trainer certification, USAW Level 1, CrossFit Endurance, CrossFit Programming Course, CrossFit Anatomy CrossFit, CPR/AED certifications and currently in a nutrition programming. <br> <br>Now, as a gym owner, wife, and mother, I know how important it is to make fitness a consistent priority. It~SQ~s not just about personal goals—it~SQ~s about setting the example for others balancing busy lives. <br> <br>At CrossFit Mischief, I’m proud to lead a community that proves every day how strong, capable, and resilient we can be when we show up for ourselves.</td></table>"))
