What's your favorite thing about teaching? I love seeing that sense of accomplishment and feeling people get after a great workout!  Plus I love making up new playlists because I love music.
Teaching at Endorphin since:
 I've been teaching since 2021 but I've been a member since 2015!
Fun Fact:
 I'm the youngest of 8 kids and my siblings and I often call each other by our birth number in large groups, so I'm forever number 8 or simply the baby to my family.  I was the only girl pitcher in a mostly male baseball league.  I have a friend that uses the story of me striking him out as a way to explain to his football team how to stay humble.  My niece is 10 months younger than me so I grew up with an automatic best friend.  We even roomed together in college and stood up in each other's weddings. I love a good IPA and love finding great breweries to try, a super easy quest in Colorado.  I love seeing live music and while Red Rocks is amazing, seeing a show at Mishawaka is an amazing experience!
