Mike's goal in seeking excellence in educational athletics is achieved by placing the teaching of life lessons on the same level as performance outcomes. This is based on his own personal experiences as a former division one collegiate student-athlete and 25 years of coaching youth club sports, interscholastic athletics, and collegiate athletics. Mike’s personal interests include music, 18th-century American History, youth, collegiate, and professional soccer. His hobbies include working out, reading, sailing, and spending time with family. Mike resides in Marblehead with his wife Vanessa.

Colleen is Waring's Certified Athletic Trainer and Health Department Chair. She holds a bachelor’s degree in athletic training from Castleton University and a master’s degree in community health education from Merrimack College. She enjoys blending her world of sports medicine and athletics with the world of health and wellness and believes that the two go hand in hand. She aims to inspire all members of the community to prioritize their wellbeing, whether that means physically when she is working the sideline of a soccer game, or in all other aspects when she is teaching health class or talking with a student on campus. When she is not at Waring, you can find Colleen reading, swimming, pulling espresso shots at Ovedia Artisan Chocolates in Amesbury, walking her dog Pepper, listening to big band music from the 40s, road tripping to Vermont with her partner Cyle, and/or eating Margherita pizza. Colleen joined Waring in 2015.
