My whole family has been working out at Mason Street for years. The trainers are amazing and super passionate about helping you reach your goals. I have trained personally with both Dan and Keith and have been so impressed with their knowledge and expertise. Their help led me to be able to play competitively in high school and college sports. Mason Street has all the equipment you could need plus two beautiful and clean locker rooms with showers and cubbies. Everything is the highest quality and I recommend it to everyone, it is the best place to work out. Thank you!

There are many places in Fairfield County in which to workout. The key difference between those, which are excellent, and those, which are superb, is the quality of the trainers and the facility's cleanliness. Hands down, Mason Street Fitness ranks as superb!

I have used multiple gyms and trainers over the past 42 years of working out.
I joined Mason Street Strength and Fitness 3 years ago and give them a 5-star rating.
My reason is simple, the trainers are excellent and the whole feel of the gym is welcoming and fun.
A recently introduced service which I have added to my workout regimen is a stretching session with a qualified stretch therapist.
At my age, I find the combination of a series of targeted strength workouts followed by a stretching session keeps me physically fit and flexible.

Mason Street Strength and Fitness is perfect for all of my children. They are budding athletes and are at that critical point where they have to begin doing weights and this organization is doing a fabulous job transitioning my daughter over. Our coach (Dan) is very attentive, watched every step, and ensure she is correctly building so that she gets stronger and she doesn’t hurt herself.

We’re already seeing the results in her strength AND attitude. We’ve found an awesome place for all 3 of our children athletes to develop athletically, safe, AND confident.

My brother, Michael (Dartmouth' 24) and I (Dartmouth '21) absolutely love training at Mason Street Strength and Fitness. Michael has been training with Keith for years for LAX conditioning and I recently started training with Keith this summer when I started training for my first ever half marathon. Still train with him today. To reiterate what's been said, I can attest to the incredible work ethic, flexible scheduling and motivated coaches.

Dan and his team are amazing trainers! You will get fantastic results with the strength training regimen they plan out for your particular needs. The most important factor is that Dan cares and hears your concerns so you are able to accomplish the goal you set out for yourself. On another note, the gym is super clean and kept in excellent condition 24/7... its a no brainer to work out out at Mason Street Strength & Fitness! 😊

Mason Street Strength & Fitness is one of the best training facilities out there that I’ve trained at. All of the trainers are very knowledgeable, helpful and encouraging. The overall vibe is great and I’ve had nothing but good experiences. I look forward to going each week and always feel so accomplished when I leave. No matter what fitness level you’re at they are very accommodating; from kids to adults and sports to general fitness. This small private gym feels more personal. Highly recommended!

I've been going to Mason Street Strength for about 3 years. The staff there has been nothing shy of amazing - they're personable, fun, professional, and make the workouts difficult but enjoyable. Additionally, the facilities are super clean. I've done both one on one training as well as group training with my girlfriends with Dan and would highly recommend both. Depending on what I want out of my workout (more cardio, more weight lifting, etc.) he will tailor it accordingly.

I have been training with Kyle at Mason Street for almost 4 years now, and it has had a tremendous impact on my life. When I started out before my freshman year, I was hoping to just get myself into better shape for my first year of high school and hopefully get some playing time on JV. By the time the summer was over, my coaches were considering me for playing time with the varsity squad, a year later I was starting as a sophomore, and then as a junior I was a captain playing both ways and getting recruited to play college ball. None of this could’ve happened without the support and help from the Mason Street staff. Not only did they help me get stronger and faster (I’ve probably increased my bench press by almost 200 pounds), but they helped me become confident as an athlete and made me realize that through hard work I could reach my potential. The entire staff has been awesome from the start and I can’t think of a better place for a young athlete like me to train. 💪🦍

I've been working out with Dan for almost 6 years now. He has undoubtedly made me a better and stronger athlete, but more importantly, he's shown me that when he trains people, it's not for one or two years, but really for 10+. He's built these relationships that go beyond sports, which is something so unique to him and his team at Mason Street. Mason Street has the best environment and mental and physical training for all athletes.

Hockey coach: I brought a group of bantam-age players to Mason Street to put in extra work to develop their strength and speed. Dan and Keith mapped out and executed a plan tailored to each kid's physical development, strength and flexibility. The kids bought into the goal-oriented training progressions, and the coaches' good-natured challenges were contagious. The facility is excellent with an awesome energy. These guys are the real deal and make it obvious that they care about each athlete's results. Bigger? Faster? Stronger? This is the place.

I’ve been training with dan for the past 5 years and without him and Mason Streets’ facility I would not be the athlete that I am today.Over the past three years I’ve gained about 45 pounds of muscle , and I’ve also gotten bigger, faster, and stronger.
