Hola and Hello! My name is Marcela Perea. I am Colombian and moved from Paris to the US in 1996. I’m married with four great kids. In 2009 I got my AFAA (Aerobics and Fitness Association of America) Certification and started training clients. The year of 2009 was when I left my career as a fashion designer to pursue my true passion – fitness – full time. Soon after, my clients’ enthusiasm and successes demanded further fitness offerings, so I began teaching small group boot camps. It was around that time that I discovered and fell in love with CrossFit.

In 2010, I achieved my Level 1 CrossFit Certification and began implementing some CrossFit workouts into my boot camps and personal training sessions. I felt so strongly about the benefits of CrossFit that I decided to get to get all the certifications I could and always working on getting more. I am truly a CrossFit certification junkie! CrossFit has certainly changed my life in a big way. It is fun, challenging, and effective for me, and my clients. Once you see the benefits of CrossFit, I know you will feel the same way.

Tina Desing

Coach

  • Certifications
  • CrossFit Level 1

For a long time I considered myself a “gym rat”. You could find me in the weight room, the cardio machines, in Spin class just about every day of the week. After having two kids, I was still plugging along doing the same boring routine when I given a challenge by a family member to complete a triathlon. I started participating in both triathlon and running events in 2004 and have completed a variety of sprint and half ironman distance triathlon, as well as cycling events, half marathons, 10K and 5K races, with a full marathon on the horizon in 2012. In 2005 I began to help others achieve their triathlon goals from the coaching side as part of a team of coaches providing group training for women.

Tom Mesiro

  • Certifications
  • National Academy of Sports Medicine (NASM) and Crossfit Level-1.
  • Golf fitness and pre-natal training.

My name is Tom, I am a fun-loving and relaxed personal trainer; certified through the National Academy of Sports Medicine (NASM) and Crossfit Level-1. I also have specialty certifications in golf fitness and pre-natal training. My client base extends between up-and-coming youth superstars or professional MMA fighters, to seniors recovering from replacement procedures or sedentary individuals looking to increase their overall activity levels.

My well-rounded and diverse background aids me in working with anyone from beginners, to both intermediate and seasoned athletes. Personal training is my passion, and I try to make working out fun and rewarding.

My underlying enthusiasm for physical training lies in my commitment to help clients live pain-free. Through a personal experience with back pain, I understand the impact a physical injury can have on your emotional and physical well-being. Because of this learning experience, I also specialize in creating individual programs for injured athletes that will not only get them back on the field, but also lead to improved performance. From athletes to anyone looking to improve their ability to accomplish day-to-day activities, I strive to work with my clients to increase their quality of life.

In addition to helping my clients achieve their fitness and wellness goals, I enjoy an active and healthy lifestyle incorporating Goruck, rafting, running, golfing, camping, and hiking. I strive to constantly learn and grow, and I am currently pursuing additional certificates to further my knowledge on nutritional health and massage therapy.

Hello, my name is Jens Wöhlbier I’m a coach at Crossfit 100. I’ve been involved with Crossfit since May 2015 when I gained my CFL1 – trainer certificate. I truly believe in the Crossfit methodology 100%. There is no other strength and conditioning program out there that is more advanced in training the body physically and mentally to prepare one for the unknowns or whatever life throws your way. As a coach I am constantly trying to improve my knowledge when it comes to bettering my athletes in ways that will shape them for tomorrow. Be better everyday, this thought comes to me every morning. So with that in mind that’s how I approach coaching.

 

Jessie Schaub

Coach

Hello! My name is Jessie Schaub. I have been training at Crossfit 100 since 2010. When my youngest child was about a year old, I was ready to get back to my own health and fitness and found Crossfit was just what I needed. I have always been active, studying classical ballet until age 18, running track in high school and competing on my high school dance team. As an adult, I missed that feeling of being part a team and the thrill of pushing myself to the limit. I love that Crossfit allows me to keep my competitive spirit alive and to be an athlete, again. Since my husband and two kids train with me, it’s also the perfect family activity!

My passion for technique and movement, and my background in teaching elementary school and kids fitness classes at Crossfit 100, naturally led me to coaching. I am Crossfit Level 1 certified and enjoy focusing on the basics with new and seasoned athletes. Moving well is key to getting stronger, faster and more fit! I also love healthy eating and cooking and using nutrition as a tool to improve my fitness.

I love our supportive and motivating community at Crossfit 100. The energy is our classes is contagious. Join us, or, for a one-on-one experience, contact me about personal training sessions.

Mark Mendelson

Coach

After 30 years as a successful sales and marketing executive, I had an opportunity to reinvent myself and pursue a lifelong dream. My dream was to help athletes of all levels achieve greater success.  After completing several degrees in psychology, I was acutely aware that athletic performance was more than just physical talent; it was also the ability of the athlete to focus and pursue what at times may seem like the unattainable. In other words desire. To train with me will challenge you to find what truly motivates you, but in the end I will help you conquer the fears and doubts that have held you back from becoming the athlete you have always dreamed about becoming.

I am an AFAA certified personal trainer, a Spinning instructor, TRX and Cyclops Power Trainer, and am presently working on achieving a kettle bell certification. Mark holds a USCA racing license and has competed statewide and nationally in several cycling disciplines.

 

Brett Keiper

Coach

My name is Brett Keiper and I am currently a student at Concordia University Wisconsin in Mequon. I have been a competitive athlete all my life. I played baseball, football, basketball and rugby as a kid and throughout high school as well as two years of playing college baseball at Concordia.

Growing up, I was very active, but I didn’t start working out until I got into high school. I was introduced to the sport of CrossFit in high school and did a workout every once in a while. It wasn’t until the summer of 2015 when I truly began doing CrossFit and joined CrossFit 100’s box. I received my CrossFit Level 1 – Trainer certificate in the summer of 2016.

I love the competitive environment of CrossFit and how it pushes people to their limits. It makes them better day in and day out; not only physically, but mentally and emotionally as well. No matter how young, old, healthy, or unhealthy you are CrossFit will benefit every stage of your life. Exercise is medicine and CrossFit is the dosage everyone needs!
