Danbury billionaire, Dr. Peter Buck, the co-founder of  the world’s largest restaurant chain, Subway, has donated a record setting 10 million to support the new Pavillion at Danbury hospital.

At an historic ribbon-cutting celebration , Danbury Hospital will open the doors to its largest addition ever: The Peter and Carmen Lúcia Buck Pavilion. The 11-story, state-of-the-art building is named for Dr. Peter Buck and his late wife.

Along with his donation he issued an innovative challenge. While remaining unidentified, he promised that if, with the help of community donations Danbury Hospital met its $50 million campaign goal, he would contribute yet another $20 million. Results of Dr. Buck’s challenge and whether or not Danbury Hospital will receive the additional $20 million gift will be revealed at 7 p.m. today.

Dr. Buck says the reason for his gift and challenge is based on his great appreciation for the superior care he and his family have received at Danbury Hospital over the years, and his desire to help provide our region with world-class health care that rivals the best academic medical centers in the country.

The event kick off begins with the Pavilion’s official name unveiling and a ribbon-cutting ceremony, led by Dr. Buck and Dr. John Murphy, CEO of Western Connecticut Health Network.

The evening ends with a fireworks show that can be enjoyed by the surrounding community.
