Meet Our Team



Dennis Monaco

Co Owner & Coach

I was introduced to CrossFit by my son, Jared who opened up his box in 2010. After several months of construction, much of which we did ourselves, he convinced me to become one of his first members.  My fears soon dissolved into a fierce determination to become a CrossFit athlete. It awakened the competitive spirit I enjoyed as a younger man playing sports. I was 58 at the time and years later, I am in the best shape of my life. I have competed and placed in several Masters’ competitions over the last three years as well as competed in the Masters Opens with two top ten finishes. But, that is not what is most important to me as a CrossFit athlete and coach. Rather, it is having the opportunity to meet and inspire others looking to make a positive lifestyle change. Through exercise and nutrition I have seen how CrossFit can alter how you look and feel and how attitudes and outlooks on life change for the better.

I am privileged at this junction in my life to be able to bring my passion for CrossFit to all our members.



Braden Monaco

co owner & coach

Being entrenched in the CrossFit Community for over 5 years before opening CrossFit Amesbury, I have found myself with a true passion for the community it creates. I use my love for people and progress to help those around me flourish as athletes and more importantly as people.

I grew up playing competitive soccer, through college and shortly thereafter used my passion for the sport to coach collegiality. Coaching was a place where I was able to use my love for a sport and my love for people to not only better athletes on the field, but help them understand how hard work and dedication transcend to every aspect of their life.

At CrossFit Amesbury, I am looking to bring the lifestyle and community that I have fallen in love with since I have discovered CrossFit  to as many people as possible. I truly believe that it is this community and the human interaction that brings such great success to those who choose to be part of what CrossFit has created.  




Jared Monaco

Co Owner & Coach

I was first exposed to CrossFit as an athlete in Fall of 2009 and quickly fell in love with both the sport and the community that it creates. I pursued my CrossFit certification in 2010 to open CrossFit Route 1 in Melrose.

I've always loved being part of a team - I grew up playing competitive soccer and lacrosse throughout high school and college. Following college I became a personal trainer and started coaching high school varsity lacrosse.  My experience as both an athlete and a coach provided for a great foundation to coaching CrossFit.  

At CrossFit Amesbury, I am most excited about fostering another community and helping our members to experience the benefits of the sport in every aspect of their lives.


Kelli Vossler

head Coach

Living in 4 states within a 5 year span is what attracted me to the badass world of CrossFit. A new town meant finding new friends who cared about living a strong life as much as I did. In 2012, I finally got the guts to walk through the door of CrossFit Portsmouth. Less than a month later, the newly rising sport made it’s way into my heart due to the incredible people I found within it.  

At CrossFit Amesbury, I am committed to bringing a unique flare to floor and helping each athlete move closer to their goals. I carry the experience of being a collegiate athlete and competitive coach, but am constantly seeking new ways to expand my knowledge within the ever-changing strength and conditioning realm. Whether coaching or throwing down, it is rare I am not smiling as I thrive when surrounded by people who want to better themselves. As a coach, I pledge to stimulate positive change within the lives of others by inspiring, motivating and empowering individuals on a daily basis.

Colette Casey

I grew up playing soccer, softball, basketball, and track, but CrossFit is unlike anything I had experienced. I played soccer competitively in high school on into college where I attended Florida State University. Our team made it to the NCAA DI Final Four 3 out of the 4 years I was there and I was captain of the team my Junior and Senior year. After college, I went on to play professional soccer in Finland for FC Kontu while starting my coaching career. I coached club, high school, and collegiate soccer for ten years while playing semi-pro soccer during the summer for Southern California teams.

Crossfit is special because it teaches us daily to maximize what we have in us for the day. You show up, start moving, sweating, smiling, talking and all of a sudden your days transformed. In a workout you push a little more, face something you thought was other wise impossible, all of a sudden you grew a little bit as a human being because you challenged your comfort zones. I am excited and passionate about bringing my experiences through sport, life, and CrossFit to Amesbury. I am lucky and blessed to have my husband Patrick and my son Bodhi inspire me daily in my career and athletic pursuits.
