  • Amy Rogers

    Amy Rogers
    Director of Services and Programs | (Website)
    Amy fell in love with fitness over a decade ago when she applied at Castle Hill. Throughout her tenure at Castle, Amy has done almost every job under the roof from customer service queen to class instructor, from smoothie slinger to handywoman (rumor has it she gives great shoulder rubs too!). Her creative skills and can-do attitude landed her a position in Senior Management overseeing the Marketing and Programs department in 2006. In 2016, she took over the management of the service department and was promoted to her current position of Director of Services and Programs. Though behind the scenes for the most part today, Amy's high energy cannot be contained and you will still see her substitute teaching a Barre or spin class here and there. She is grateful for her coworkers and Castle Hill clients for making everyday a good day to come to work. Her ultimate goal is to inspire others to see their true potential and discover their optimal path to long lasting health.
