The Team

Owners Caleb and Kati Terray

Caleb and Kati Terray


Not a gym person? We get that! And neither were we until we opened Breakthrough. We met in college at the California Institute of the Arts studying music and theatre. We would never have suspected then that we would end up diving deep into fitness. Curiosity led us to try a kettlebell seminar in 2008, and we’ve been learning as much as we can about strength training, human movement, the science of programming, and other fitness related topics ever since. We took our first Kettlebell Instructor Certification in 2009, initially just for our own sense of accomplishment. We started sharing our training with some family members and friends, and before we knew it some of their friends and family also wanted to give it a try. We were too excited not to keep learning and sharing, so as our group got bigger, we converted our home garage into a training studio. We kept seeing how much more our clients got out of the whole experience when they were sharing it with like minded people. We kept experiencing that as people felt stronger and more capable physically, they also started to feel more confident and fulfilled in other aspects of their lives. We kept hearing from people that they had never really considered themselves “gym people”, or that the traditional gym environment didn’t meet their needs in some way. So, in 2015 we made the leap from our garage to open Breakthrough. We knew there must be lots of people who felt the way we felt, and our clients felt, so we wanted to create an even larger community where people who may not have considered themselves “gym people” felt welcome. If you’ve ever felt like the traditional gym setting isn’t for you, that doesn’t mean you aren’t a “gym person”… You just may not have found your gym yet!
