I grew up in De Pere, Wisconsin (near Green Bay) playing sports and have been extremely active my entire life.  The sports I was most passionate about are soccer and wrestling. I attribute the majority of my athletic success to my encouraging support group of coaches, teammates and family.  Because I was fortunate enough to have so many positive influences early on, I recognize the impact in helping others reach their goals.  I strive to be an example to others, showing people that you can truly live your best life, helping them find their support systems and encouraging them to put in the work!

I attended college at UW-LaCrosse to follow my passion for health and fitness. I earned a double major in Pre-Physical Therapy and Exercise Science with a Nutrition Minor.  I realized that I was genuinely passionate about teaching fitness and helping inspire people to find their "why" and achieve their wellness goals.

With just over ten years of coaching, I can proudly say that I have coached hundreds of clients of varying ages.  Their transformations include: losing over 100lbs, decreasing over 20% body fat, and helping high-performance athletes develop speed, agility, increase max strength, and overall improved functionality.

When you commit to becoming a member of i2 Fitness I know that we will help you reach your goals. We will hold you accountable in an environment that is innovative, friendly, motivating, and exceeds your expectations.

Like my twin brother, I also grew up in De Pere, Wisconsin. Surprise, surprise, I led quite a similar life to my brother during the first 18 years of my existence. People often ask me what it is like being a twin. I think it is awesome and it has been a fantastic journey thus far ... then again I wouldn’t know what it’s like to not be a twin:). 

My brother and I decided to take different paths in college so we could develop our independence. Plus, we didn’t want to be known as the Puck Twins forever. I decided to attend and wrestle at the University of Wisconsin-Stevens Point, where I graduated with a bachelor’s degree in Health Promotion/Wellness. As a curious and adventurous person, I enjoyed my college experience and loved the freedom of exploring so many new opportunities. At one point I was part of 11 different intramural leagues! I was interested in anything that involves movement.  

To me, the most significant aspects of training/sports are the atmosphere (teamwork, camaraderie, sportsmanship and community) and growth potential (achievement, failure, results, progress and being challenged).  The desire to create this type of atmosphere and growth potential for our clients is what led us to start i2 Fitness

I have always led an active lifestyle -- there are not many sports I haven’t played. As a personal trainer and an athlete, I know the value of moving and moving well.  I also know that the physical aspect of health and wellness is only a piece of the puzzle and encourage each person I work with to dig deep and figure out “why” they are here and how we will develop good habits that will last a lifetime.


The best feedback that I have gotten from my clients is that I am a good listener.  My clients know that I am there for them and that I will support them in their success and help them navigate their struggles. I do my best to bring positive energy to every session while remaining focused on achievable goals. Whether you need a modification or you’re ready to take it up a notch, I will show you how to master your moves so you feel confident working out in class, with me or on your own!


I hold certifications as an ACE certified personal trainer and fitness nutrition specialist, TRX Qualified Trainer in: suspension, group and functional training and PreHab 101: Prehab foundations.

I was born in Southern California but I have lived in the Madison area for my adult life. I started dancing at the age of 3 and danced competitively all through High School. After graduating High School I went on to Massage Therapy School. Once I completed my schooling I was working full time doing Massage Therapy and returned to my love of dance and started teaching dance classes. My passion for helping others was growing and with that I decided to start training clients to help them with their health and fitness goals. I have been training clients since 2004. I am passionate about challenging clients to dig deep and push past their limits to hit the next level.


I currently live in Stoughton with my husband (Les), twin boys (Chane and Parker), daughter (Bexley) and their dog (Chester). I love the sunshine and being outside. I also enjoy spending time with my family and friends and going out to the family farm.


I am certified in Personal Training, Group Fitness, Bootcamp and Yoga. My favorite classes to teach are Bootcamp, HIIT, Strength and Circuit Style. I love 1:1 training and seeing my clients excel at crushing their goals.

I have been passionate about fitness since I was a little kid playing kickball at recess. I loved the fun of exercising, and the feeling of being part of a group.This love grew into an opportunity to play volleyball and basketball at a D3 college in MI where I learned to work and play hard. My desire now is to inspire and help others along their fitness journey, to see that an active lifestyle has transformational physical, mental, and emotional benefits. I have been teaching group fitness classes for the last 2 years, and am also an ACE certified personal trainer. I believe everyone can take steps toward a healthier, richer life, and have fun doing it!
