Instructors
At CFSV, your coaches know who you are.
NOTE: We are actively looking to hire (and train!) new coaches. If you have a dream of becoming a great trainer in a great community, especially if you are female, enby, or trans, we want to help you achieve that goal. If you’re interested in a job with CFSV, send us an email.![21636300079_afa8d78acc_k](http://crossfitsomerville.com/wp-content/uploads/2015/10/21636300079_afa8d78acc_k-300x199.jpg)
Sea is pretty cool, but he still needs to write a blurb for the website. Feel free to give him a hard time about it.
Sianna Casey, CrossFit Coach Sianna is a CrossFit Level 1 Trainer who has been coaching since 2019. Sianna was first introduced to CrossFit in 2013, when her family opened a box in Roseburg, Oregon, and she’s been in love with the sport ever since. In college, Sianna rowed crew as a walk-on (Go Wellesley Blue!), and she credits CrossFit with her willingness to jump into a brand new sport. Constantly varied, high-intensity, functional fitness prepares you to try new things! Sianna is passionate about safe movement and solid technique… and then getting heavy and pushing hard. Ask her for tips on workout strategy and on mindset to get gritty during tough WODs. Outside the gym, Sianna works as an educator at a nonprofit and is always happy to talk about U.S. history, algebra, or whatever random concept she’s been talking about with her students that week. Natalia Saunders, CrossFit Coach Natalia has Crossfit Level 2, Burgener Weightlifting Level 1, Russian Kettlebell, NASM Personal Trainer, and TRX Certifications. In her own words:![](http://crossfitsomerville.com/wp-content/uploads/2024/01/nat_jumping-1.jpg)
Since I started attending the conservatory at a very early age (and probably because I didn’t displayed any natural athletic gifts to be written home about) I had resigned myself to be the funny chubby sidekick to my incredibly athletically gifted wife (who was one of my very first CrossFit Coaches!). However, during the pandemic I decided to see what would happen if I tried my very best. To my surprise, I fell in love with running, completing a half marathon almost every Sunday during my “long runs” during lockdown, and qualifying for Individual Quarterfinals and Age Groups in 2021, 2022 and 2023. This past June I tackled one of my ultimate challenges and ran a marathon! As someone that needed to take a walking break for a 400m jog 7 years ago starting CrossFit, this was to me the real proof that the only limits we have are the ones we set for ourselves.
What I love most about coaching is being able to help others find their inner strength and confidence. My ultimate goal for every single class I coach is to show everyone that we all are capable of so much more than we think, and sometimes all we need is someone to believe in us.
Originally from Mexico City, in my spare time you can find me complaining about how cold it is, cuddling with my two English bulldogs: Missy Elliott and Cardi B, and “forcing” my wife Candy to watch reality TV.”
