NASHUA — With 50 years of service at the Boston Air Route Traffic Control Center, employee Patricia Clark is receiving a tremendous honor.

President Barack Obama recently signed into law a bill that authorizes the facility on Northeastern Boulevard in Nashua to be renamed the Patricia Clark Boston Air Traffic Control Center.

“Over the course of her career, which spans five decades, Patty has shown an unparalleled dedication to public service. We’re incredibly proud of her, and this is a fitting tribute to her extraordinary service to our state,” said U.S. Sens. Jeanne Shaheen and Kelly Ayotte, and Reps. Annie Kuster and Carol Shea-Porter in a release.

The New Hampshire delegation worked together to pass legislation in the Senate and the House of Representatives to rename the control center in Clark’s honor, which became official on Aug. 9.

Clark has worked as an administrative assistant at the facility since it first opened in 1963.

“Mrs. Clark has never taken annual or sick leave. According to her colleagues, Mrs. Clark’s dedication to her job is as impressive as her length of service to the Federal Aviation Administration,” said U.S. Rep. Rodney Davis of Illinois, who spoke about the issue earlier this summer on the House floor in Washington, D.C. “To recognize her dedication, Mrs. Clark’s colleagues decided it was appropriate to celebrate Boston Center’s 50th anniversary by renaming it in her honor.

“The dedication and hard work of federal employees like Mrs. Clark should not be overlooked,” added Davis.

Kuster also spoke before the House of Representatives earlier this summer in strong support of the bill that she helped introduce. Kuster described Clark as the “gold standard” for federal employees, adding Clark has never taken a sick day in the past 50 years.

“To quote one of her colleagues, she is simply the ‘cream of the crop,’” said Kuster.
