Our management team has made fitness their lifelong passion. See how our founders and executives took their background and experience to make Orangetheory Fitness the phenomenal business model it is today.

Ellen Latham M.S.

Ellen is a highly trained physiologist with a lifelong passion for health and fitness. Her desire to be on the cutting edge of fitness inspired Ellen to design “The Ultimate Workout,” which became the foundation for Orangetheory Fitness – hailed by the New York Times as an effective new plateau-busting workout. Ellen is a Partner and Founder of Orangetheory Fitness, and Owner of Ellen’s Ultimate Workout gym in Florida.

Inspired by her father Arthur Calandrelli, a very popular Physical Education teacher and coach in Niagara Falls, NY, Ellen has been motivating and training clients for over 35 years. She holds a Bachelor’s Degree in Physical Education and a Master’s Degree in Exercise Physiology from the University of Buffalo in New York.

Before perfecting her signature workout, Ellen worked at the prestigious Bonaventure Spa when it was the main fitness retreat for the stars, as well as managed Williams Island Spa and The Eden Roc Spa on South Beach. She served as a TV fitness expert for six years, authored fitness columns for The Miami Herald and South Florida Sun-Sentinel and earned the title of Business Woman of the Year in South Florida. Through her position as fitness editor for Women’s Fitness magazine, Ellen began focusing on Pilates and opened the first group equipment-based Pilates studio in Ft. Lauderdale, Florida.
