    Client Testimonials

    • As a physician, there is nobody I would trust my patients with more than Sean Joo. There are many factors that can keep people from reaching their goals and without specific knowledge and real intelligence any physical training program can lead to wasting time, money, and effort. Most personal trainers will do a good-enough job “working you out.” I know the patients of mine that are assessed, trained, and educated by Sean will have a dramatic advantage in achieving and maintaining their health and fitness goals.

    • Sean is an exceptional fitness trainer. I felt he really listened to me on the first day we worked together. I wanted to discuss my goals, but I was also concerned about an old shoulder injury. In the past I have felt that other trainers that I worked with glossed over anything that wasn’t “happy and positive”. Sean was really concerned with my injury and then proceeded to customize an intense, thoughtful, safe workout that I thought I was not capable of attempting because of my fear of my shoulder “going out”. The amazing thing is, I was on my way to getting in the best shape I’ve been in years as well as watching an old chronic injury finally heal under his care and custom designed workouts. Sean’s workouts both strengthened my body and rehab’d my shoulder at the same time. His knowledge is excellent. By the way, he walks the walk. That man is in ridiculous condition himself!

    • I must confess I went into training with Sean with great trepidation. I’d never worked with a trainer before and I didn’t think I’d make it through one session. With Sean all my fears and worries were unfounded: Sean is warm, supportive and really fun. The pace and difficulty were just right. I felt challenged but not overwhelmed. Sean has a great depth of knowledge about the body, anatomy, and nutrition so he was able to work to my individual needs and offer alternatives and suggestions. In just a short time with Sean’s training I’ve already noticed a change in my body and I feel great. Thanks Sean!

    • Working out with Sean is great! Not only did he guide me through a challenging set of exercises, he also shared nutritional tips that are really easy to implement. The whole experience was awesome!

      Ellen Brown, NJ
    • If you want a personal trainer who is demanding, but amiable and supportive, then Sean is the personal trainer for you. In each session he is positive and energetic, but in a sincere way, not saying a lot of empty platitudes like you get with many other trainers. I am a relatively young guy (29), but nevertheless have knee troubles–on days when my knees are especially problematic, Sean has been willing an able to adjust the program to either work with the issue or around it, but never bullying me to push through. Outside of sessions, he’s very responsive to emails with questions, thoughts or comments about routine and especially about nutrition. He’s very concerned about your whole program–everything you’re doing and eating, not just when you are training in front of him. Sean is a really excellent trainer to work with.
