In case you don't know, these are rival schools and I caught a lot of flack from my family when I switched, but I have always been an Ole Miss fan and still cheer the Rebels on through every football season. I met my husband when I was 15 and after a 2 year split in college we reunited and have been married since 2013. In my spare time I enjoy doing anything outdoors. I've been a long distance runner for years and can say running is my true passion. I enjoy biking and doing the occasional triathlon.

She is even more excited to be able to stay in Colorado and continue to explore the natural beauty and adventure that the state has to offer.
