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.
