Our Story

Over the Years



Don Whitney & Barbara Tregellas

  • Don Whitney started Corporate Sports Unlimited, Inc. (CSU) with Barbara Tregellas on July 1st, 1980, after he moved to Atlanta, GA from Puerto Rico, where he served as the Head Tennis professional for Sports Illustrated and Rock Resorts at the Dorado & Cerromar Beach Hotels.
  • In 1981, CSU had its first major event; a team building event for Johnson & Johnson with 300+ people. CSU went on to produce 13 events in its first year.

The Beginning

Cary Tregellas – Director of Corporate Health Unlimited from 1985-1995

  • In 1983, CSU received a call from the General Manager of the new 5 star Waverly Hotel in Cobb County, GA to operate and manage their on-site health & fitness center, and to bring their teambuilding event concepts to the conventions of the Waverly Hotel.
  • In 1984, CSU was called to open and manage the Ritz-Carlton Buckhead Hotel Health & Fitness Center. This led to CSU being the exclusive vendor to open other Health & Fitness Centers for the Ritz-Carlton Hotels & Resorts, including: The Ritz-Carlton Naples, Palm Springs, Rancho Mirage, Kapalua, Laguna Nigel and others.
  • CSU also served as a consultant to Hotel Nikko in Chicago and Atlanta, The Swiss Hotel Atlanta, Sheraton Hotel Chicago, Inn & Links at Spanish Bay, and the Waldorf Astoria in New York.
1987 - 1999

The Inspiration

Don Whitney – 1990 IBM Team Building Event

  • With two divisions now operating at full speed, Corporate Sports Unlimited, Inc. formed two divisions that identified closer to their line of service; Corporate Events & Meetings, which today is Corporate Events Unlimited (CEU) and Corporate Health Unlimited (CHU).
  • By now, CEU is producing 100+ team building events annually serving over 500,000 employees and CHU is managing 12 corporate fitness centers reaching over 150,000 employees for their health and wellness needs.
  • In 1994, Don pursues his personal passion of starting a national road race (The United States 10K Classic) to give 100% of all funding to children that are in the greatest of need, which would lead to bringing worldwide awareness to what would become The World Children’s Center. The U.S. 10K Classic would go on to run for 17 years (1994-2010) and become the 6th largest multi-sport national road race in the United States.
  • In 1995, Don wins small businessperson of the year by the AJC and the Atlanta Business Chronicle just prior to the 1996 Olympic Games.
