Sean Stellmach

Owner/Fitness Coach

Sean Stellmach began his career as a fitness coach at a Fitness Together near his home in Massachusetts. Having entered the field with a bachelor’s degree in community health education from UMass Lowell, and a NASM (National Academy of Sports Medicine) personal training certification, Sean was excited to work with clients and help them achieve results. He was immediately comfortable in the training studio and truly enjoyed coaching clients in their fitness journeys.

After just one year, Sean came upon the opportunity to purchase Fitness Together Newburyport where he quickly increased business and churned local interest in his new studio. He compiled a highly qualified team of fitness coaches and witnessed many client success stories, and continues to do so today. Fitness Together Portsmouth was acquired by Sean in early 2012. This studio was built much like the Newburyport location, and is now a premier personal training establishment in the greater Portsmouth area.

Sean believes that fitness can and should be fun AND effective. Much of his free time in the summer/fall is coaching the Amesbury High girls’ varsity soccer team. But he and his fitness team understand that sometimes, exercise takes a back seat in life, and it’s difficult to begin any fitness program. His goal is to motivate, empower and improve the overall health of each and every client who walks through his doors.

As a former competitive athlete, Taylor knows the importance of a well-planned physical training routine in order to maximize an athlete’s mental and physical potential. His life changed forever at age 16 when he suffered a spinal cord injury playing in a junior hockey game in Canada. Initially paralyzed from the waist down, after lengthy spine surgery and more than 2 years of inpatient and outpatient rehabilitation, he now walks without assistance despite mixed paralysis in his lower body.  He attributes much of his success in rehabilitation to my former dedication to training for sports as a young teenager.

Taylor believes that the most effective strength and conditioning programs are those that incorporate a proper balance of injury prevention, sport specific skill practice, strength, plyometric and speed exercise, and strongly believes that developing healthy habits through exercise early in life can positively impact other areas of a person for a lifetime.

Keith Dorr
Keith Dorr

Keith Dorr

Fitness Coach

Keith has lived in Maine his entire life. He grew up in a small town named

South Berwick, which is often mistaken for "Marshwood" because of the

very popular high school within the town. He has been active his whole life and

heavily  involved in sports. Baseball was his main sport throughout high school, but

recently he has started playing for a semi-pro football team, the seacoast war hawks out of Dover, New Hampshire.

 

His journey into personal training has a couple of key factors that led to the fitness training career choice. Between cardiovascular health risks running in the family, and the passion and drive to help people create better lives for themselves, fitness training was the healthiest and the most logical. When it all comes down to it, it’s about being able to help people reach their goals and hopefully affect people

in a positive way day after day.

 

Keith received his certification through the All Pro Sports and Fitness Association and is CPR/AED certified through the American Red Cross association.
