Alex a registered dietitian

She completed Ironman Wisconsin in 2014 and as she crossed the finish line one of her first thoughts was, "If I didn't have my shit together with my nutrition, I'd never have made it through the day." It was right then and there that she felt her calling to help other endurance athletes reach their goals and dreams.

Her food philosophy is simple, fun and flexible. As an athlete herself, she fully understands the struggles that you experience, and she would love nothing more than to help you gain the understanding and confidence you need to fuel your body to its fullest potential.  

Most days you'll find her working at home in yoga pants with a golden retriever at her feet. If she's not doing that, then she's mommin' it up with her two little boys. Her favorite meal is breakfast, and she live for the weekends when she has time to whip up a stack of scrumptious pancakes.

I’ve spent years failing badly at bikes so you don’t have to. I have a mortgage, two kids, a wife, a dog that doesn’t listen, a weakness for Miller Lite, and fish frys – but I can still turn a pedal if I have to. Chances are we’ll get along just fine.
