At CFSV, your coaches know who you are.


JT Scott, Instructor

JT is a CrossFit Level 2 Trainer who enjoys introducing new and formerly-untrained athletes to the prospect of unlocking their genetic potential. He is dedicated to the goal of maintaining CrossFit Somerville as a facility that provides access to life-changing fitness education and inspiration to all comers. In addition, he is a Biomedical and Electrical Engineer, Licensed Massage Therapist, anatomy nut, and chronic experimenter in new methods. He tends to handle many of the members nutritional planning and diet questions – having a lot of personal experience in these fields.

As the first CrossFit Affiliate in downtown Boston, JT founded CrossFit Fenway in 2009 and then CrossFit Somerville in 2011. He sold CrossFit Fenway in early 2016 to focus more on Somerville and his family.

JT’s passion is creating a welcoming environment at CFSV and motivating members to use conscious choice as a practice in their lives inside and outside of the training facility. His mission is to change the world.

Outside of CrossFit, JT is proud to serve as the elected City Councilor for Somerville’s Ward 2 (2018-present), where he lives and works at CFSV. His work and the environment here are informed by his experience as an intersectional queer activist, and his service on the Founding Committee of Union Square Neighbors and as a Director of Union Square Main Streets. He has also been a (literal) fire-breather and fire-eater with the Boston Circus Guild, amongst his many other interests.


Nick Detar-Koch, Instructor

Growing up as a competitive swimmer, Nick took for granted the benefits of the lifestyle of an athlete. After college (a music school where there were no sports) he found himself feeling much less healthy than he thought someone in their mid-twenties should. He stumbled on CrossFit through dietary research he was doing as well as the search for more functional based fitness than he felt he was getting at the gym of the YMCA he worked at.

After following it a bit on his own (read: cherry-picking workouts off of, a friend told him a CrossFit gym was opening up in Union Square. He went to a free trial at CrossFit Somerville and never looked back.

Before becoming a CrossFit instructor Nick was the coach of a swim team of 120 kids from ages 5-18. He has a passion for learning how what we put in ourselves affects us physically, mentally and spiritually and loves finding new ways to build efficiency in the way we move.

Micheal Augustine, Instructor 

Coach Michael has been involved with helping others attain higher levels of fitness for a long time. From teaching people to swim in high school with the American Red Cross, training his soldiers in the 82d Airborne Division, building a $1M fundraising MS event team, teaching SPINNING for over 10 years, and a CrossFit Level 1 Trainer with Hanscom Warrior Training Center before moving to CrossFit Somerville, he has had one goal; to help people be the best version of themselves. 

In his own words:

“There are few things as satisfying as helping someone finally accomplish something they have been chasing, from climbing a rope to getting a PR on a lift. Helping people improve to be stronger, healthier, and happier is incredibly rewarding and I have never seen a program that does it better or faster than CrossFit.”

We all want something; faster, stronger, fitter. You can have that thing and we can show you how to get there; but no one can give it to you, you have to take it. You’re stronger than you think. For the magic to happen you need to get comfortable with being uncomfortable”


Nelly Oliver, Instructor 

Nelly joined CrossFit Somerville as an athlete in August of 2013.  If you read her member profile you’ll get a glimpse of her evolution from a reluctant and frustrated new member to the enthusiastic, energetic coach she is today! 

From her first class as an athlete to 5.5 years later learning the ins and outs of coaching from JT, Mel and Kirstie her love of CrossFit and this community continues to grow daily.  She is always interested in new opportunities to learn how to benefit CFSV members and continue to strengthen this community.

In her own words:

“I am the strongest and fittest I’ve ever been since joining CrossFit.  Once you commit and become consistent progress can be limitless. I tell everyone, CrossFit is infinitely scalable.  Whatever your fitness level, you can come in and get a great workout while working towards long-term health benefits.

It’s a great feeling when you know an athlete leaves for the day feeling satisfied that they’ve accomplished something they didn’t think was possible and that your encouragement played a role in that.”

Jenna Buckle, Instructor

Jenna is a CrossFit Level 1 Trainer and joined the coaching staff at CrossFit Somerville in 2019. Jenna was always involved in athletics growing up, having played soccer competitively for years. She started CrossFit in 2015 (at the encouragement of her cool uncle!) to fill the fitness void when her soccer days were over. Little did she know that walking into the garage doors of CSFV would change her life — helping her grow mentally and physically in ways she couldn’t have imagined! 
As a coach, Jenna loves getting to share her passion for health and fitness with athletes at CSFV. She enjoys helping people unlock their potential in the gym so that they can go out and crush it at life.

Karina Baldelli, Admin, Sales & Billing 

Karina started Crossfit in September of 2014 when she moved back to Somerville and Nelly (who was not yet a coach) essentially forced her to sign up.  Karina grew up playing sports competitively so she likes how Crossfit challenges her athleticism and pushes her in ways she definitely would not push herself. Unlike her previous exercise habits, Crossfit Somerville helped shift her mindset to a much more holistic, balanced approach to health, which she is really thankful for. She loves handstands and watching members come out of their shells as they find their groove within our community.

Here at CrossFit Somerville, Karina handles the emails, member inquiries as well as all of the CrossFit Somerville memberships. Outside of CFSV, Karina is a part-time personal chef and full time mom. She also organizes CSFV’s partnership with Community Cooks where members of our community volunteer to provide meals for a local women’s shelter once a month.
