Robert Sax

Owner | Coach

I’m from Portland, Maine born and raised. Went to Springfield College in western Massachusetts and got my Bachelors in Science in Exercise Science and have my CrossFit Level One, CrossFit Football, and CrossFit Kids Certification.

I moved up to Seattle right after I graduated because I heard it was a great place to live, and two years later, I owned a CrossFit gym and am a part of the greatest community of people that I could ever possibly imagine.

I love CrossFit workouts. They’re much better and different than anything I’ve ever done before. Having constantly varying workouts means never getting used to doing the same thing over and over. And having a group of people that always push and encourage you to do new things is by far better than any workout or exercise program I’ve ever been a part of.

I’ve played sports my whole life and CrossFit has made me a better athlete, even now, in my later years. If I had it earlier in my life, I would have been twice the athlete.

Tanner Hoskins

Coach

Hey RoomMates! My name is Tanner Hoskins. I’ve been doing Crossfit for 6+ years and coaching for 1. Fitness / nutrition has been a major part of my life since I was introduced to Crossfit and I’ve most recently loved coaching and showing people what their bodies are capable of! I’m originally from Spokane and about a year ago I moved to Seattle with my wife, Maddie. She is a busy third-year student at the UW school of dentistry. In the short time that I’ve been at Amped I have noticed what a great, welcoming community that has developed here and I’m truly excited to be a part of it! Outside of the gym, I work in tech, enjoy riding my motorcycle and just recently got into camping and loving it! We also have a German Shepherd named Zeus! I look forward to seeing you in my classes!

CrossFit Level 1 Certificate Holder

Mason Alexander

Communication Manager | Coach

I grew up playing a lot of sports all the way through high-school and into college. Through my love of football, I developed an interest in weightlifting as well. I became a personal trainer by my sophomore year in college and really began to enjoy helping others become better versions of themselves.

It wasn’t until my wife introduced me to CrossFit, that I was able to take on a whole new level of understanding and appreciation for health and athleticism. With her guidance and encouragement to attain my CF-L1, I found true passion in the development of others. I drive focus towards bodily awareness, foundational strength, good technique work and patience as vital ingredients to this cocktail we call functional fitness.

Kevin Chen

Manager | Coach

Fitness is my jam and CrossFit is my passion! I love CrossFit because it has created a community that focuses on helping people of all ages live healthier and more active lives.

One of my favorite things as a coach is being able to make positive impacts on each member’s health and fitness. As a coach, I am caring, energetic, and loud at times. I aim to make each class fun, competitive, and I hope that each athlete comes back stronger and more confident than the last time.

Outside of CrossFit I love to eat, travel, hike, snowboard, and hang out with friends and family.

Kai Siddiqui

Coach

I grew doing gymnastics, wresting and playing football. In 2013, I found CrossFit and fell in love. It was about performance, technique, improving little by little. It was exactly what I needed. For the last 6 years I’ve dedicated my life to helping people reach their health and fitness goals. When I’m not in the gym you’ll find me exploring nature with my family. Everything we do in the gym will be reflected in what we are capable of doing outside. Simply put, my goal to make everyone who comes through the doors, the very best version of of themselves.

Levi Dempsey

Coach

I started my CrossFit journey in 2008, having arrived here by way of a road of years in martial arts (Karate, Tae Kwon Do, Kung Fu, Tai Chi, Ba Gua, and Capoeira), and the intense desire to not get fat. The emphasis on technique and form before intensity, and the supportive yet challenging nature of the group classes, and beginning nutritional knowledge drew me in.

One day, while helping another member work on pull-ups, she exclaimed how that was the first one she had ever done in her 63 years on this earth, and she was floored and ecstatic. It was a life-changing event I was witnessing, which in turn changed my life. I became motivated to become a coach and help more people make dramatic positive changes in their lives. I began coaching in 2010, which lead me to take a CrossFit Gymnastics seminar, which got me hooked on the movements and strength of gymnastics. I began to practice on my own and took classes at a circus school to learn even more.

In 2014 I was accepted as a coach for the CrossFit Gymnastics Seminars, which is one of those great jobs that just feeds your passion. I work hard to bring that knowledge to my everyday coaching, and always coach like I would want to be coached. This means I will ALWAYS be on your case about better body position, safer movement, and correct technique. Speed is one side effect of excellent technique. Fitness is another.

Suparno Chakrabarti

Coach

I grew up in the Pacific Northwest playing soccer, water polo, and tennis growing up as well as taking advantage of all the outdoors here had to offer. Skiing and snowshoeing in the winters, hiking, swimming, & biking in the summers were the only way we spent our weekends around here. In college, I went from a 3 sport athlete to a significantly less active individual. In 2013, I decided I wanted to be fit and fast like I used to be and bought a Group On to CrossFit for 20 sessions and did all 20 days straight. I was also blown away by all the awesome people who also showed up everyday! Looking back, it’s just amazing to see how much more I can do whether it be lift more, or move faster! I’m not looking to be the strongest ever, just move good well into my old years and this seems to be the way to go for me!

Maria Lambo

Coach

Hi, I’m Maria (in the gym mostly known as “Lambo”). Health and fitness have been the center of my world for most of my life. As a kid I was always doing something active and constantly trying new sports and activities. Volleyball, dance, golf, and running were my favorites. In 2014, a friend had me try Strength and conditioning/Crossfit and I have been in love with the sport ever since.
The human body and helping people have always been passions of mine and working as a registered nurse and a coach allows me to truly help people across the entire health spectrum. In the gym, my favorite parts of coaching are dialing in technique, helping everyone understand each movement or workout and what you will gain from it, and to help push your mental boundaries so you see what you are capable of.
