Founder, Owner CORE57,


Master Trigger Point Trainer



“I have the best job in the world!! I get to help others for a living. I have always been active and a competitive athlete so moving for me has always been a huge part of my life. Teaching other to find the very best of themselves is what I love most about what I do. There are so many people that are a afraid to work out or who don’t think that they will ever be able to reach their goals. These are my peeps. These are the ones that I want coming through our doors. There is nothing sweeter than showing our client that they can DO It.

I was a competitive gymnast in my younger days and then went on to compete on the national level as a collegiate cheerleader. My favorite exercise is a handstand. I hope to be able to perform it when I am 70. I love outdoor adventures - skydiving with my hubby, rock climbing with my son, and white water rafting with my family of seven.

When I am not working, my happy place is with my family. Combined, my husband and I have 5 kids. There is never a dull moment. We love adventures together and we love to make each other laugh. There might even be a funny scare or two every now and then.

The meaning of CORE57 in my eyes…. Physically, Mentally and Spiritually Strong. We all need more of this!”

Two words to describe them: Passionate and Determined”

Favorite quote: “Set your goals high, and don’t stop til you get there.” Bo Jackson


I have always loved fitness but must admit that working out was not a passion of mine. I was a competitive golfer my whole life but did not put the work in when it came to working out. Through my wife’s eyes and her desires to teach a healthier lifestyle to community, fitness became important to me. Working out allow me to stay active with golf, skiing, and hiking. I love to stay active outside and living a healthier lifestyle allows me to fight the aging process.


I love that I get to do what I love best alongside my partner in crime. Together Jason and I make a great team. He has been my biggest supporter in making my dreams come true and I so blessed that we have been able to grow CORE57 together. Our passion is making fitness realistic and accessible for anyone no matter what challenges they might face. 

Our story:

The name CORE57 was inspired by our family – together we have 5 kids and that makes us a family of 7. We then used these numbers to develop the 5 Steps of Success and the 7 Foundations of Fitness. We both realize that it takes more than a workout to hit your fitness goals. It is the way you live your life that makes the biggest impact. CORE57 is more than just a business for us – it is our extended family. Our members and our staff make CORE57 great.
