When New Milford Hospital opened its dedicated cancer center in 1999, hospital leaders and staff never imagined the community support that would help expand the facility's specialized cancer care and technology.

The Diebold family of Roxbury is one "shining example of that generosity," said Deborah K. Weymouth, senior vice president and executive director.

The Diebolds have donated $4 million to New Milford Hospital to fund cancer treatment equipment, including an upgraded linear accelerator with a robotic couch for targeted therapy, and the open-bore MRI for sharper imaging and greater patient comfort.

To celebrate the Diebolds' ongoing charity, the hospital has renamed its cancer center as the Diebold Family Cancer Center, recognizing their steady and progressive gifts.

The Diebolds' longstanding support for New Milford Hospital has been a combination of personal funds and monies from their family's Diebold Foundation, as well as the estate of Dudley Diebold's mother, Dorothy, who died in 2010 at age 105.

Dudley and his wife, Nonie Diebold, along with the other Diebold Foundation benefactors, Caitlin Diebold, Daphne Diebold Stoughton and Kevin O'Connell, were honored Oct. 25 during a reception hosted by New Milford Hospital and Western Connecticut Health Network Foundation.

Nonie Diebold described her family's care at New Milford Hospital as "an incredible experience."

"It's wonderful to be able to do this," she said. "We give because we want to, and it's the right thing to do. If it helps reassure people that New Milford Hospital is here to stay and to serve our community, we're happy to put our name on it."

Ms. Weynouth agreed.

"Along with investments by Western Connecticut Health Network, community support has helped New Milford Hospital surpass the level of quality and expertise that is typically available in a community hospital setting," she said. "We are achieving our goals because our community truly shows how much it cares about the people of this region.

"Our newly renamed Diebold Family Cancer Center is a thriving place for all who need these important services, and we are extremely grateful for the charitable leadership of the Diebold family."
