Mark Migliorini

Owner and Certified Functional Strength Coach

Mark has been with Fitness Together since January of 2016.

He graduated from Assumption College in 2010 with a Bachelors Degree in Organizational Communications.  He is a level 1 Certified Functional Strength Coach by Mike Boyle's CFSC program.  He is also CPR certified through the American Safety and Health Institute and served in the Massachusetts Army National Guard until 2016.

As a former Fitness Together client, I know first hand the benefits of 1 on 1 personal training.  By going to Fitness Together not only was I able to achieve my fitness goals, I was able to achieve a healthy lifestyle. You get real results here and are able to accomplish things that seemed impossible. Fitness is my passion and I want to help you achieve your goals anyway I can.
