our story
Jason is the owner of CrossFit Prowess. He has over 9 years experience as a full time coach with a background in Engineering. After finding Crossfit in 2010, he began coaching at his original gym in southern Virginia, CrossFit Oyster Point, in early 2011.
He quit his corporate job in the summer of 2011 and spent 8 months learning the business and honing his skills as a coach, with his eyes set
on moving north to open CrossFit Prowess. He made the leap and opened Prowess on April, 2nd 2012. Prowess started small and knew we would expand into the space as the business grew. Jason obtained his CrossFit Level 2 trainer qualification in early 2012 as well as Weightlifting, Kettlebell, Endurance, Mobility, and Gymnastics, among others specialty courses over the years.
With over 10 years of experience as a CrossFit athlete and coach, Jason has taught well over 6000 classes and hundreds of athletes. Jason believes that CrossFit is a means to do the things you enjoy and a path to a healthier life. Our methods have been simple from the start, a coach lead class focusing on general physical preparedness paired with a habits based nutrition program providing knowledge and accountability.
Our focus on building a welcoming community that gives new members an immediate sense of belonging. Our goals continues to be providing a place to move, meet friends, have FUN and feel welcome. We have learned so much, made some mistakes, but also done a few things right along the way and can’t wait to continue being a place that changes lives for the better.
Prowess has become a place where members look forward to coming in and forgetting about the stressors of their day, if only for an hour. Jason is so proud of the entire team at Prowess and we are excited for the future. We cannot wait for what the next ten years of growth and evaluation brings.

Kristen Van Hull
GENERAL MANAGER
NUTRITION COACH
CROSSFIT TRAINER
Kristen’s passion for health and fitness is only surpassed by her enthusiasm for helping others to reach their goals. A two-time Division I National Championship rower at Brown University, Kristen then started competitive running shortly after having her two children, qualifying for both the 2016 and 2017 Boston Marathon. While training for Boston, she took up CrossFit to increase her strength for her running, but she soon fell in love with the sport, and quickly traded in her running shoes for Nanos! The hard work, competitive spirit, and community aspect of CrossFit are what have Kristen hooked, particularly at Prowess. Kristen wholeheartedly believes that nutrition is the foundation of CrossFit, as honing into her diet has personally helped her to see tremendous gains in her overall health and performance. As General Manager, CrossFit Trainer, and Nutrition Coach at Prowess, Kristen is committed to helping people in the East Bay community improve their health and well-being through fitness, nutrition, and the support of like-minded people – and is passionate about empowering and motivating them to get fit and stay healthy for life.

Nicholas Agosta
HEAD COACH
Nicholas started his fitness journey in 2010. What started as a healthy outlet for a kid who struggled with body image and self-esteem, evolved into a lifestyle rooted in self-improvement and growth, overall health and wellbeing, and a genuine love for helping others achieve their fitness goals and improve their quality of life. Nicholas currently holds a CrossFit Level 1 Certification and an Advanced Coaching Concepts Certification. He is also certified in personal training, strength and conditioning, and kids fitness through ISSA.
From 2013 through 2016, Nicholas was the Athletic Director for a private school in New York, where he prepared students for their sports season and instilled the importance of hard work, determination, and teamwork. Nicholas found his love of CrossFit in 2015, and became certified in 2018. A true student of the sport, he continually pursues opportunities to expand his knowledge of the CrossFit methodology and become a better coach. He is also pursuing a degree in Kinesiology at the University of Rhode Island.
Nicholas has had the privilege of working and belonging to multiple CrossFit communities throughout his career, and is happy to have found a home with Prowess in 2022. He is committed to creating a positive training environment for all, and believes the work we do inside the gym not only improves our fitness and health, but also helps develop skills that will lead to happiness and success outside the gym. In addition to coaching, Nicholas is a C-130J Loadmaster in the Air Force. He loves spending time with his wife, Sara, and dog, Kilo, as well as hiking, archery, and talking cars and comics.
Emma Rains
NUTRITION COACH
As a Type 1 Diabetic of 15 years, Emma has learned a lot about nutrition and how different foods affect the body over the years. When she started CrossFit three years ago, Emma got to put a lot of that knowledge into practice and learned how to fuel her body even better through the Prowess nutrition program. The healthy habits Emma put in place helped her feel stronger in and outside of the gym. As a nutrition coach, Emma values putting what she’s learned into practice. She loves meeting people where they are at to create the foundation for a healthy lifestyle, so they can spend more time doing the things they enjoy!
