Melissa Huntington 
Fitness Director

Melissa is the Fitness Director of Kingsbury Club Medfield. She has been a certified fitness professional since 2006 and joined the Kingsbury Team in 2012. She started her health and wellness journey in 1998 after graduating from the Bancroft School of Massage Therapy. She quickly became confident performing many different modalities but especially excelled in deep tissue/sports massage and loved educating people about their bodies.

Melissa has worked with celebrities and elite athletes including the Men's and Women's U.S. kickboxing teams, Gravity Games athletes, and the New York Giants. Her breadth of experience as a massage therapist brought many of her clients out of physical crisis, but she also realized the limitations of massage-only for the treatment of certain injuries and thus developed a growing interest in exercise science and nutrition. Melissa expanded her career into the fitness field and continued her education at the National Personal Training Institute in 2005 and became a certified trainer and nutritional consultant. She also completed her CrossFit level 1 certification in 2013 and is TRX and Kettlebell certified.

Melissa uses an individualized approach to assess, motivate, educate and train clients regarding their personal health and fitness needs and goals. She designs safe and effective exercise programs and provides guidance to help each client achieve results. She prides herself in building trusting relationships with her clients and she is committed to helping people lead a healthier life so they can be the best possible version of themselves. Her passion is empowering people of all ages and levels of ability to reach their personal best and to live fully in body, mind, and spirit.

Melissa grew up a three sport athlete (soccer, basketball, and softball) all through high school and wishes she realized sooner the importance of eating healthy and taking care of her body. She now enjoys playing on the Holliston’s woman’s soccer team and will play pick-up basketball, softball, or pickleball whenever she gets the chance.

Steve Gurtowski 

Confidence in your ability to meet life’s physical demands is one of the key aspects of living well, and Steve is committed to helping you fit fitness into your life.

Steve has over 24 years of strength, health, and fitness coaching experience under his belt. His training philosophy is based on time-proven practices and grounded in experience and an athletic background. His interest in fitness began as he watched his role model, his grandmother, maintain her strength well into her 80s by staying active and working on her farm. As a result, “keep moving to keep healthy” became the cornerstone of his philosophy.

One of his core beliefs being that smart fitness training doesn’t rely on high-tech equipment or the latest workout trends. Instead, he uses a mix of sensible strength training, smart lifestyle strategies, and time-tested tools for building strength and conditioning.

Every client enjoys a personalized training plan with their specific fitness levels and goals in mind, whether it’s building strength for health and longevity or recovering from an injury. He has worked with all groups ranging from youth athletes to grandparents.

His specialties include: filling the gap between post-physical therapy and full function, helping those with “bad backs”, the active aging population, and desk bound workers feel and move better again.

Jeremy Dillon

Jeremy is a Certified Strength and Conditioning Coach (CSCS) with over a decade of experience helping kids and adults build strength, overcome injury and be more athletic. It’s a fact, the more fun we have the easier it is to work hard…AT ANY AGE! If you know an exercise is prescribed to serve a specific purpose, it’s easier to give more effort. Jeremy finds the balance between education and fun to build intrinsic motivation so you want to work harder, not because you have to. If you haven’t met him, Jeremy looks like Tigger from Winnie the Pooh because of the way he bounces around the training room.

In 2009, he graduated from Westfield State College with a B.S. in Movement Science and a concentration in Health and Fitness. In 2018 he became Level 1 Titleist Performance Institute Certified (TPI) to help golfers reduce pain and add distance to their game. He is currently pursuing his Precision Nutrition Level 1 Certification to help people that have struggled with their diet build sustainable results.

Sports are fun and training should be too! Just because you don’t play on a team doesn’t mean you are not an athlete! The “everyday athletes” are working professionals, moms, dads, grandparents, weekend warriors and so-on that want to stay healthy to live their lives to the fullest. The smarter you train in the gym, the more capable and confident you will be when taking on life’s demands!

Growing up a two-sport athlete, he understands the demands sports can have on an athlete as well as their family. In high school he suffered a severe football injury that ended his season and put his spring sport season at risk. The rehabilitation process failed to prepare him for the demands his body would be facing which lead to another injury. Years later after understanding the rehabilitation process he identified the gaps in the system and created programs to help keep others from falling in!

This sparked his passion to help competitive athletes and “everyday-athletes” reduce their risk of injury, build confidence and unlock their potential. He has achieved this through building smarter training programs that fit each individual’s lifestyle and goals in a fun, educational environment.

His specialties include: golf fitness, youth athletic development, team training, Olympic lifting, return to play (closing the gap for athletes between physical therapy and getting back on the field), lifestyle/habit coaching for long-term change, personal training, small group training, and large group training.
