  Born and raised in CT, Nadine's passion for dance started at the young age of 2. Although she loved all types of dance, by the age of 10, her love for ballet inspired her to join the New Haven Ballet, where she would later dance in The Nutcracker, The Snow Queen and La Capella.  After receiving her B.A. degree from Assumption College, Nadine earned a law degree from New England School of Law and has been specializing in real estate law since December of 2004.  However, Nadine has always had a love for fitness.  She took her first Barre class a few months after the birth of her 2nd daughter and was instantly hooked.  Nadine has completed her barre training with Boston Body Barre and is excited to bring her ballet background and passion for health and fitness to the Cal-Zone. 

Her goal is to motivate and inspire her barre students throughout class and have them leave feeling confident with themselves and stronger in body, mind and spirit.
