About Me:

I started my CrossFit journey to improve my health and fitness. I fell in love with it immediately and was surrounded by a great mentor and community. I began coaching Strength and Conditioning for Football and Baseball at Arcadia High School in CA at the same time that I began coaching CrossFit classes. I love to see the transformation that people go through. Seeking improvement and challenges are my biggest motivators and finding like-minded people to keep me accountable is a real gift.

About Me:

I started doing CrossFit with my family in 2012 in my hometown of Ashland, Oregon. Outside of CrossFit, I am an avid dancer with 15+ years of experience in various dance styles and instruction. I have also participated in a number of endurance races such as the Portland Marathon and Bass Lake Triathlon and love everything in the outdoors!
Over the years I have grown to admire the diversity and passion of the CrossFit community. Getting people moving, learning and reaching their goals gets me out of bed everyday and I am thrilled to be part of the Full Strength family.

First introduction to fitness was in the water. I was in the water every summer since before I could stand. Spent all of my childhood and teen years competing in swimming. Later taught swim lessons and coached swim teams as well. Starting high school I got into the typical gym lifting. I also took to cross country finishing with a PR 5k of 18:00. Once I started college I was hitting plateaus on all my lifts and decided CrossFit might help mix things up. Immediately fell in love. A year later I got my Level 1 to see what the magic behind the madness was. A year after that got a coaching position to hone in on my coaching where I spent numerous weekends studying or attending additional CrossFit seminars. I still plan to continue on that path until I receive my Level 3 and 4.
