Assistant Coach

In my family I am known as the most active person. Growing up I had a great childhood and I was always active. (Thank you mom for paying for all those years of dance classes!) However during my college years my activity level decreased. I went from dancing six days a week to zero, and working out at a commercial gym. I was more focused on “looking good and being skinny” than being healthy. That all changed when I started CrossFit about four years ago. My mentality of “looking good” changed to “being the best version of myself.” I exchanged my craving for being skinny to being strong barbells became life! #allkindsofgains As the years went on my whole view on health developed. From counting calories to focusing on whole foods, my interest in CrossFit became more than just working out; it became a lifestyle. I started to notice my family members decrease in functional movements; specifically my grandparents and I knew then that I was on the right path. I was sad that my grandparents didn’t have the luxury to learn about the positive effects of fitness, let alone have time to work out. When my grandfather became severely ill and it opened up my eyes as to just how important your health and exercise is (specifically functional fitness).


  • CF-L1
  • CrossFit Kids Trainer
  • My biggest contribution as a Coach?

    I am empathetic, diligent, and motivated. My goal is to teach those that are interested about fitness and nutrition. I want to empower people and illuminate the importance of investing in yourself and your health, because let’s be honest it may just save your life.

  • What brought you to coaching?

    I started working out at Origin Fitness about four years ago. However, I never knew that I would grow to appreciate and love CrossFit as much as I do. With each passing year I developed as an athlete, and my passion and curiosity to learn more only grew with time. I recently completed my CF-L1 and couldn’t be happier! I am excited to continue to learn as both an athlete and a coach.

  • Favorite movement or workout?

    Any workout with a barbell and/or Olympic weightlifting!

  • Least favorite movement or workout?

    Thrusters… yuck!

  • What do you like to do outside of Origin Fitness?

    I enjoy dancing, watching Netflix, traveling, trying new and interesting restaurants, and spending time with my family and friends.

  • Advice for someone starting or wanting to start CrossFit or exercise.

    Just try it, don’t be shy, and consistency is key!

  • Finish with a joke.
