After having four kids and struggling with lower back pain for years, I found Built in Boston and started working out with Sean in January of 2024. It was the best decision of my year! I look forward to every workout because each one is challenging, thoughtfully designed, and fun. I have seen so much progress through increased strength, vanished back pain, exponential growth in energy levels, and new confidence that my body will be able to do the things I want it to do for the coming decades. Sean has incredible expertise in all things fitness and human performance - but makes it all accessible and practical. I’ve recruited several friends to work out with me - I just can’t stop talking about how great a benefit working out with Sean has been, plus it’s all encouraging, positive vibes, and any amount of experience is perfect for getting started in the gym. Come train with Sean - it’s a truly worthwhile investment.

Train with Sean! I turned 40 and started working out in August at Built in Boston, and it was one of the BEST decisions I made. Sean is expert, approachable, encouraging, and FUN to train with. Every workout is distinct and he clearly puts tons of thought into every class to challenge us to improve. The culture of the gym is also so encouraging. Since I started, I feel so much stronger carrying my kids around, running, swimming, and have no low back pain anymore and I can do the monkey bars again with my kids! Training here is an investment in yourself that pays back thousand-fold. I can’t recommend Built in Boston with Sean highly enough!

Sean is a skilled trainer who spends the time to get to know his clients, asking plenty of questions to understand the full picture of what your goals are and how he can help you get there. I came to him with an existing workout regimen that I wanted to supplement with more rehab-focused movements and he took the time to assess my weak areas, understand my current training schedule, and create workouts for me around those parameters. I am moving and feeling much better than when I first started seeing him thanks to the time and effort he put in. Regardless of where you're at in your workout journey, if you are interested in getting some 1 on 1 guidance, Sean is an excellent coach to work with.

Can’t recommend Built in Boston highly enough! Sean is extremely knowledgeable, super friendly, and dialed in; the gym space is pristine and well supplied. Sean encourages a whole-body, mobility/conditioning/strength approach, and has made me both fitter and smarter about my workouts and health. Truly awesome!

Sean's a great trainer. He does a good job building in warm ups, and makes you do the exercises correctly. He's really good at helping you do the exercises you don't want to do but know you should be doing

Started personal training with Sean post Achilles rupture. He has been amazing to work with, getting my ankle mobility and stability back where it needed to be while improving my overall strength and mobility. He is super knowledgeable, and happily gave me the feedback I needed to ensure I was learning new movements properly and able to progress in complexity and weight. Training to grow old gracefully.

I have been training with Sean for the better part of 15 years. Sean's attention to form and technique set him apart. His expertise with kettle bells is unsurpassed. More importantly though, Sean finds a balance between routines that are challenging but achievable. As he says, train for gain not for pain!

Sean is a great coach! He's attentive, kind, thoughtful, and funny. He knows how to cue movement and make corrections so that you can get strong safely. He makes both classes and one-on-one sessions fun! Thanks for being awesome, Sean!

We started training with Sean in 2013. He's the best fitness coach I've ever worked with including cardio, strength, flexibility, balance, and nutrition. Sessions are long-term and short-term goal-oriented. I've lost weight, increased my strength and balance all while learning new techniques and achieving new goals I never thought possible. The workouts are challenging in a very positive environment. Sean helps you stay accountable to your goals. And he is also excellent at adapting movements to those with limits to their range of motion.

Sean is an amazing trainer and fitness professional! I went to him for help with losing weight and my overall fitness and he was able to help me with my diet, exercises and routines outside of his gym, and daily discipline. His training sessions are no joke but I always felt amazing after them and like my whole body was getting the movement it desperately needed. Hes a great guy and an awesome trainer to work with. 10/10!

2019 I started working out with Sean over at Built in Boston. From my experiences over the last several years I can only speak with the most highest regard, Sean’s dynamic training abilities took my health and fitness to levels I would have not reached one my own. His dedication and professionalism to the health and fitness industry is admirable. I look forward to continuing my training Shaun at his newest facility !!

Sean takes an individual approach to each client. I’ve trained with him on several occasions , for several different goals in mind and he’s tailored an effective training regiment that is not only effective with him during personal training but also transferable when you’re working out on your own . “ Built in Boston” is equally “ Best in Boston “ when it comes to personal training .

I was in the area was interested in getting a personal trainer. As soon as I walked into the studio before I could even get a word out the trainer immediently told me I had to get out it was a private studio and they are in the middle of something. Exteremly rude and fast way to lose business.👍👐

Great place. Great trainer. Sean is very personable, knowledgeable, and is great at tailoring workouts for different styles of individuals and groups. Training with him I've dropped 70 lbs, and gone from not being able to do 1 pushups to now deadlifting 325lbs (working towards 400lbs). I loathe standard cardio (running, biking etc), but he makes it fun using combinations of kettle bells, medicine balls, jump rope, rowing, you name it. Could not have done it without him. Highly recommend. Weight training? Go there. Cardio? Go there. Trying to figure out how to get healthier? Go there.
