I grew up in Germantown, WI and moved to La Crosse with my husband Ken after our wedding so we could spread our roots here. We immediately fell in love with the charm of the city, the views of the river and the bluffs, and how active of a community this is. In my free time, you can find me cheering for all Wisconsin sports teams, finding any excuse to pet every dog I come into contact with, or figuring out what my next adventure will be!


I attended UW-Madison where I got my Bachelor’s degree in Kinesiology with a certificate in Global Health. I am passionate about fitness and wellness, as well as helping people in any way I can. It was clear to me that Castle is all about helping people too, which is why I wanted to join them! I’m so excited to be a part of the Castle family, and to meet and work with all of the wonderful clients who put their trust in the Caste team!


Come and experience the commitment!
