Coaches & Owners


I have been involved in fitness and athletics all of my life.  I knew at a young age that taking care of my body and exercising would benefit me for the rest of my life.  In 1994 I started my own personal training business.   For years I worked with clients helping them get fit but something was missing and I could never put my finger on it.  In February 2009 I was introduced to CrossFit.  For the first time in my life the true definition of fitness was clear to me.  I was given a road map on how to get fit and help others do the same.  Working out is now fun, challenging and motivating.  I am in my mid-40s and can honestly say I am in the best shape of my life.  After my experience with Crossfit I knew I had to share it with others.

I have been teaching wellness and nutrition for 25 years, as well as coaching sports and personal training since 1987. I have a Bachelor in Science from Springfield College and a Masters in Education from Framingham State College. I have been a competitive athlete all of my life and have personally trained clients of all ages for over 25 years. I have had multiple knee surgeries and shoulder surgeries, including a shoulder replacement. I was told by doctors that I would never play baseball, rock climb or lift weights ever again. CrossFit has not only allowed me to prove them all wrong, but has rekindled my innate desire to compete by helping me discover that fitness can be a sport and anyone can be an athlete. CrossFit has revived my health and fitness and elevated that of my students and clients. My experience coupled with my passion can lead you closer to your goals. “If you can believe it and conceive it, WE can achieve it”

After have been told by my doctor that competitive contact sports were no longer an option due to numerous shoulder injuries, I felt lost. I decided to give triathlons a try, but the monotonous training was providing me with little to no satisfaction.  That’s when I serendipitously ran into Coach Glenn. I tried the free Saturday class and knew then that Crossfit was the answer I was looking for. I want to share my story with everyone I meet, and help change their lives the way Crossfit has changed mine.  My goal is to help kids and teens train in a way to help prevent the unnecessary injuries I suffered at a young age.  Favorite quote: “It’s all in the hips”  Coach Chubbs Peterson

I am 32 years old, married and have three beautiful children ages 7, 5, and 4.  I reside in Northbridge and teach art at Holliston High School.  I have experience coaching high school baseball, hockey and football and am currently a football coach for Blackstone Valley Tech. in Upton. Other interests of mine include camping, hunting, and fishing when I can squeeze any in. I first discovered CrossFit online in an attempt to spark my then stale fitness practices.  Little did I know it would turn my world upside down for the better.  For six months I followed the main site a few times per week at home and at school until CFS was put on the map.  I began at CFS a couple of mornings a week and instantly began to notice two major changes. One change was obvious, I was losing weight and getting stronger, something my old routines had lost.  The other change was my attitude and daily take on life.  I truly believe that because of CrossFit and everything it encompasses, from the wods and healthy habits it promotes, to the community and spirit it breeds, I have been an all around better person, husband and father.  I am very excited to continue on this positive life path as a coach and CFS family member. See you soon in our wods!  Matt Blood (otherwise known as “Blood” on the whiteboard)

Playing sports and being active have always been a part of my life.  The decision to pursue this field in college was a natural progression for me.  I received my Bachelor of Science at Salem State University.

After college I became a certified personal trainer and group exercise instructor.  I worked for 3 years as a Senior Fitness Specialist and Group Exercise Director for the corporate employees of EMC.   In 2010 I tried CrossFit for the 1st time and was instantly hooked!  CrossFit made me evaluate not only the way I was staying fit and healthy but also the way I wanted to educate people on reaching their optimal fitness and health.  Coaching CrossFit was the next logical step for me.  I have my CrossFit level 1 certification and am excited to be coaching at CrossFit Synergistics.  For me, CrossFit is pushing yourself outside of your comfort zone in a fun and effective way.  CrossFit gives you results! Its evidence based programming full of high intensity, constantly varied functional movements will not only make you love the way you look, but you will feel good from the inside out!

My journey to CrossFit is a similar story to most.  I am a competitive person by nature. I played Volleyball and Softball through college as well as being on the swim team.  I am now a middle and High school Physical Education teacher.  As an adult, I continued to play sports to quench my thirst for competition.  When that wasn’t enough I dove into Triathlons.  As someone who likes a team atmosphere you could imagine that the training got monotonous and lonely.   I found CrossFit in the best way possible.  One of my high school students said to me at the end of the school year, “Ms. Severance, you should come do CrossFit with me in Ashland I know you will really like it, and then we can do it in PE class next year.”  This kid loved CrossFit Teens so much he wanted to share it with me and all the other students at our school.  I knew if that was how he felt then it must have been really awesome.  I strolled in on a regular day in the beginning of summer just to do a little window shopping.  I told Glenn who I was and why I was there, his reply was epic.   He said “I knew you were coming into my life today.  Don’t ask me how but my wife and I were just saying that someone who loves kids and fitness is going to come into our lives.”  From that moment on I was on a path already designated for me.  I was hooked and ready for anything CrossFit threw my way. Teaching kids to have passion for fitness and health has always been my mission, but CrossFit has given me the strength and direction to ensure that my mission is successful.  CrossFit makes people better. CrossFit Kids makes better people.

I finally found what I had been missing. I found intense competition, crazy silly fun and more than that I have a CrossFit family to train with.  I knew CrossFit would make me stronger and faster and I was right; I am in the best shape of my life.  What I wasn’t expecting was the transformation CrossFit had on my mind and my soul.  I have never felt more confident, more alive and more complete since starting CrossFit.
“Agh I have to go to the gym”  SAID NO CROSSFITTER EVER!!!
My favorite CrossFit family moment was when a student athlete and intern charged out of the locker room in the middle of our 6:30am WOD and proclaimed, “I did it.  I got into the university of Maryland”.  The whole box erupted with genuine cheers and congratulations. Everyone was truly overjoyed for a young man they “only knew from the gym”.  I cried.

I started CrossFit as a way to get into shape for my final year of high school basketball.  I had played basketball all my life and wanted to get a step up on my fellow teammates to earn some valuable playing time on the court.  In just two short months, I went from finishing in the middle of the pack on sprints a year before to winning every sprint without keeling over and gasping for air.  I knew after my high school basketball career I would want to pursue CrossFit and take it more seriously, although, I never thought it would change my life.

Once I started focusing on CrossFit, I realized it was about so much more than just me.  All of the coaches truly inspired me to help others and become a coach.  I saw how they changed people’s lives on a daily basis, including mine.  The transformation of an athlete after a mere six months was unbelievable.  They were so much happier and sociable, and I knew I wanted to be able to make that difference just as the coaches have done with all the athletes at the box.

Fitness is now a huge part of my life.  Having just completed my first year of college, I look back and it’s scary to think about how different my life would have been without finding CrossFit.  CrossFit has allowed me to venture outside my comfort zone and change my life for the better.  Instead of gaining the freshman fifteen I actually lost the freshman fifteen!  Everyone always tells me how lucky I am to have started CrossFit at such a young age, but the truth is, even I wish I had found it sooner in life.

I have been involved in teaching Health and wellness for the past 5 years. My journey began with powerlifting and through that I discovered CrossFit in 2009. From that point forward my whole life turned for the better and crossfit became the center for my training. As an NCAA ice hockey athlete I have found that CrossFit can be used on and off the ice and more importantly be used in everyday life. The competitive edge and the constant challenge it brings to the table is unmatched as you are always trying to better yourself no matter what the situation is.

For the first 8 months of my husband CrossFitting I was hesitant to jump in. After taking my time to comprehend functional training and realizing the variety kept me from getting bored I began training in our basement garage gym with my friends for early morning wods. I quickly discovered the addiction to the competition and camaraderie. Each month that passed I discovered I was achieving more and more goals. I took a foundations course and experienced the community environment of a CrossFit and it was just the remedy from the routine of the gym scene. I took my level 1 certification course simply to become a better athlete. Now I look forward to my training and coaching at CFS.
