ABOUT ME: I’m born and raised in eastern North Carolina and have worked in banking for the last 12+ years.  I began running in 2013 while trying to recover from ACL surgery and worked my way up from running 3-5 milers on the weekends to running my first marathon within 6 months. Three weeks later, I ran my first 50k and I was hooked on ultra marathons. Most of my training runs take place on the roads, but I love running trails!  Since I started running in 2013, I’ve completed 25+ ultra marathons, 15 marathons and countless ultra distance training runs.  Running has also enabled me to lose close to 70 pounds so it’s easy to say that running has given me new life and it’s one that I’ll keep trying to get the most out of it!


  • 5-100 mile finishes (PR of 19:18)
  • Completed Rim-to-Rim-to-Rim run (Grand Canyon, AZ)
  • 20+ ultra marathon finishes over 50 mile

WHY TEAM OS1st: I found OS1st in 2017 when I started dealing with plantar fasciitis and immediately started using the FS4 PF socks on runs in conjunction with FS6 compression sleeve during the day.  Since first using OS1st products, I was able to return to running and able to get back to training pain free.  I’ve even completed 2-100 milers in the months after first dealing with plantar fasciitis!  I’ve also embraced the recovery products from OS1st and use the CS6 calf sleeves and FS6+ compression sleeves routinely during the weeks while training for my next race.
