Nico Seretto


Nico's love for all things sports began at a young age when he started pop warner at the age of seven and continued into his mid-twenties with semi-pro football. He graduated from Fitchburg State University in 2011 with a bachelors degree in Exercise Science and a concentration in Clinical Exercise Physiology. Upon graduation, Nicobegan to work exclusively with athletes of all ages primarily in a strength and conditioning facility. Although he enjoyed his experiences with those athletes, he slowly began to realize that he could have a greater impact on those who needed an extra push, a guiding hand, or a person who could hold them accountable. All signs pointed Nicotowards private personal training. He began working for Fitness Together in the spring of 2012 as a Fitness Consultant. Right away he noticed his passions developing from the results his clients were getting. The atmosphere of Fitness Together, highly customized programs, and top notch training is what private personal training is all about. Nico firmly believes there is no other way to do it. He worked his way up to Management within the studio and in December 2014 had an opportunity of a lifetime...he became the owner of the Fitness Together in Auburndale, MA! This has easily been one of the best decisions Nico has made not only because he loves the company and everything it stands for, but he gets to go to work everyday and help improve the lives of each and every one of his clients. 

Kerry Seretto


Kerry's background has always been helping people but in a different way than she is now. Kerry has over 5 years experience as a Real Estate Agent finding people their forever home, and now she is finding people their forever strength and motivation.

Fitness Together appealed to Kerry for multiple reasons. She enjoys the close-knit feel that the larger gyms do not offer and the private, personalized attention that each client receives. "Building relationships with my clients" is what Kerry says is her favorite part of being a business owner. You can occasionally find Kerry on the training floor with clients if she isn't visiting all three Newton studios doing day-to-day tasks.
