About Us

A single vision… to a DYNAMIC TEAM.

The Transformation Center was started 15+ years ago through the vision and hard work of a single person. Since then, it has become so much more. As of January 2022,  the TC is now owned by its three full-time trainers, Brent Berger, Liz Grosspietsch, and Erin Tallard, and the community is thriving with a new energy and excitement for healthy living.

At the TC, all of our trainers and staff are passionate about helping our members LIVE their best lives. We encourage our members to assess where they currently are, develop a plan for where they want to be, and help them embrace the change and growth that comes with shifting their lives in a new direction. We do this by focusing on our three pillars of fitness, wellness, and community.

A place where people come to TRANSFORM

The Transformation Center IS NOT a big box gym, and we don’t pretend to be. Instead, what you’ll find is an inviting atmosphere where people (trainers, staff, AND members) get to know each other and genuinely care. It’s a place where people come to transform their fitness, mindset, nutrition, health and beliefs about what’s possible, all while being surrounded by a safe and supportive community of other people striving for the same thing. Our trainers are recognized as some the best in Madison and meet people where they are, regardless of whether you are just getting moving again or are a seasoned gym-goer.

Community and People Come First.

We are the un gym. The place where community and people come first. The place where you never have to worry about what you wear, whether you know how to do the exercises, or what you look like– because we welcome all.

Our motto is “Come as you are.” And whether you’re a seasoned gym-rat or this is your very first time, we are proud to be your new home.

What makes us different?
We know that getting and staying healthy is not easy in this day and age. For that reason, we’ve built our programs with the whole you in mind based on our 3 Pillars of Success: Fitness, Wellness, & Community.

With all three of these pillars in place, you have a solid foundation on which to build a lifetime of healthy habits.

But if you are missing any one piece, you may find that you can make progress for awhile, only to slide backwards at some point.  We specialize in helping you put all of the pieces into place.

What We Provide Our Members

  • Fun and challenging workouts that are always different yet easily modified to any ability level.
  • Healthy and tasty recipes and meal plans to help you lose weight and improve your nutrition.
  • Workshops and events that help you discover and tap the power of your mind to make permanent changes in your daily habits, your nutrition, and your health.
  • An amazing and supportive community, complete with social events and a space to hang out and build relationships, that will keep you coming back.

We know that it can be hard and potentially intimidating to start this journey and to stick with it.  Especially if you’ve tried and failed before.

We’ve built our entire program around helping people like you to be successful.  And not just for the next 6 weeks or 6 months. We want you to succeed For Life.

Secret superpower: I am an amazing tree climber. Sometimes still I will do it for exercise, it's really fun, challenging and dangerous. When I was a kid the neighbors used to yell at me because my head would stick out of the top of the trees.

Something no-one knows about you: I don't know song lyrics so instead I make up my own words and sometimes they become hits within the family.

Favorite place to travel: Massachusetts to visit my family.

Favorite TC memory: The party Gus and Courtney threw for Dennis and the bootcamp before his surgery. It was great to see the support. We truly have the best community.

Most exciting thing you've ever done: Cliff diving is so thrilling. I love it because it's dangerous and I am in complete control. It's terrifying but exhilarating at the same time.

Workout or exercise you'd rather never do again: I really dislike long slow cardio workouts indoors. When I was training for triathlons I'd have to bike on the trainer or run on the treadmill and it got really boring I need to do intervals or be outside to stay interested.
