Katie Warechowski

Katie Warechowski

SVP - Client Success

Katie has always had a passion for being healthy and fit as a nationally ranked diver and a gymnast in high school; and now enjoys playing tennis. She originally wanted to be a doctor but knew that would take time away from a family she one day wanted to have. So, she decided to help people in another way - by helping them reach their health and fitness goals. Katie and Mike now have one child, Michael who is 7 years old. She graduated from Kennesaw State University in 2005 with a Bachelor's Degree in Exercise and Health Science. She’s a nationally certified personal trainer and a Fitness Nutrition Specialist through one of the most highly recognized organizations, the American Council on Exercise. She loves continuing education so Katie is always reading about the latest health and fitness studies. She incorporates all different aspects of health and fitness into her programs to help her clients achieve maximal results. But be careful, she's not known around the studio as "Killer Katie" for nothing.

Mike Warechowski

Mike Warechowski

SVP - Client Systems

Mike's passion for health is as strong as anyone's! He did not always have this appreciation for health and fitness, however. Raised on junk food and candy, Mike struggled with his weight as a kid and did not have any knowledge about eating right until a few years into college. He began educating himself on health & fitness. When he realized he could help others do this as well, he began studying Exercise and Health Science at Kennesaw State University. He graduated with his Bachelor's in 2004 and has been working for Fitness Together since 2002. Mike is also a nationally certified personal trainer through the American Council on Exercise. He worked as a trainer for many years, completed his internship through Fitness Together, became the manager, and finally purchased a studio with his wife, Katie, in 2006. Mike keeps the studio running like a well oiled machine. Making sure the clients receive top notch customer service and personal training is one of his main goals. Mike loves working with people, no matter how challenging their struggles may be.

Sean Sullivan

Sean Sullivan

SVP - Marketing

Sean grew up an athlete playing every sport you can think of, but had to stop playing contact sports in 6th grade when he was diagnosed with a benign brain tumor. Without football in his life, he excelled as a world champion Irish Dancer to stay active. During the height of his dancing career, Sean worked with a personal trainer for core strength and conditioning; so he knew the benefits of working one-on-one with a fitness professional. He decided to dedicate his life to helping others achieve their health & fitness goals, and pursued a career as a personal trainer. In 2005 he graduated from the National Personal Training Institute and has been managing Fitness Together studios ever since. He has extensive experience training a wide range of clients, Sean is also very active in the community, especially of the Chamber of Commerce. When he is not working he likes to spend time with his family, especially his wife Marion and their son Padraig. You can often find them with their dogs hiking on the trails.

Lisa Petersen

Lisa Petersen

SVP - Sales

Lisa began her FT journey as a client which gives her great perspective. As a mother of 3, working part time, the President of her children’s PTA, all while they played 6 sports...to say her life was busy would be an understatement. In 2008 she was tired of looking & feeling the way she did, so she called Fitness Together. It was time! Those sessions would change her life in so many ways. Lisa met her trainer Steve and knew right away it would be hard work but fun. He pushed her and he believed in her more than she did herself! With a lot of cardio, nutrition and journaling she lost 38 lbs and 22 inches in 4 months! She’s stronger than ever and truly a different person. She knew she had to do this for others and help more people to feel the same way, so at 41 decided to partner with her trainer Stephen. In 2009 they committed to changing the lives of others by opening a Fitness Together. Since that time she also received her personal training certification!  Lisa is excited to bring her passion and experience to FT Tysons!

Stephen Kopshaw

Stephen Kopshaw

SVP - Operations

Stephen’s career in personal training started purely on accident. He liked to stay in shape doing activities like hockey, firefighting, football, track & field and more recently obstacle course races. After going to school for computer engineering he realized life wasn’t simply about making money and being good at something, it was about enjoying what you do and making a difference.  He left school to pursue a career in firefighting. While training for the state fire exam test he took a job at a gym & found his true passion. He believes that eating healthy is a way of life, not an instant fix, and the same applies to exercise. After training for a private studio, he knew this is what he wanted to do. He partnered with one of his clients, Lisa to open a Fitness Together and has enjoyed it ever since. His number one concern is always the clients and their results. He strives to give every person what they need, not a generalized “thing”, and is always thinking of ways to improve your experience, your results, and most importantly, your life!
