Erin WentworthErin Wentworth, MS | Member & Program Coordinator
Erin brings a dynamic educational background to the WCWI team with her Bachelor’s Degree in Education from the University of Wisconsin - Oshkosh and a Post-Baccalaureate in Elementary Education from UW-Milwaukee. Erin’s professional career path traveled down a different road when over ten years ago she lost 125 pounds through healthy lifestyle changes. This dramatic lifestyle change inspired her to pay it forward by merging her new found passion of living a healthy lifestyle with educating others. In December 2018, she completed her Master’s Degree in Health and Wellness Management through the University of Wisconsin - Extension Green Bay.  Erin’s ultimate goal is to teach others that living a healthy lifestyle is not a chore and success is all about taking smaller steps toward better health.
As the Member and Program Coordinator at WCWI, Erin manages the registration experience for programs and membership. Fueled by her ambition to assist employers in creating cultures of health and to help employees live their best lives, Erin supports WCWI employers in finding solutions and connecting them to cutting edge resources and tools. In addition to her current role at WCWI, Erin is also a Wellness Coach and fitness instructor at the Wisconsin Athletic Club (WAC). Outside of work, she enjoys being active at the gym and outdoors, spending time in her family’s pool, and watching her nieces and nephews grow up. Erin also spends her time visiting and playing with her family's rescue dog, Macie.
