Los Alamos Site Office Revitalization Manager Named
Jun 26, 2007

WASHINGTON, D.C. -- Donald L. Winchell, Jr. has been tapped to be the manager of the Los Alamos Site Office at the Department of Energy's National Nuclear Security Administration (NNSA). Starting July 8, 2007, Winchell will lead the approximately 100 federal personnel who oversee the contract management of security, quality assurance, environment, safety and health issues at NNSA's Los Alamos National Laboratory. He will focus on revitalizing the federal oversight and management role of the site office.

"We are excited to have Don on the NNSA team. The Los Alamos Site Office and its employees are an important part of our nuclear weapons complex," said Thomas D'Agostino, NNSA's head of defense programs.

Winchell has worked at the laboratory since August 2004, where he most recently served as a technical staff member and operations support division group leader. Prior to joining the laboratory, Winchell was the vice president and deputy general manager for operations of Johnson Controls Northern New Mexico, LLC, which provided maintenance and infrastructure support to the facilities at the laboratory.

After completing 30 years of service in the U.S. Navy, Winchell retired from the Navy in 1999. His assignments included service on four nuclear attack submarines, including command of USS DRUM (SSN 677). From 1989 to 1991, he commanded Submarine Squadron 22 in La Maddalena in Sardinia, Italy. Other tours included program management of a defense liaison division project, assistant chief of staff for material and logistic support for the Atlantic Submarine Force, executive officer of the Atlantic Nuclear Propulsion Examining Board and assignment to the Bureau of Personnel.

Born in Maryland, Winchell was raised in Los Alamos, New Mexico and currently lives with his wife in New Mexico. He has a Bachelor of Science in engineering physics from Oregon State University.

Daniel E. Glenn, who has served as acting manager of the site office since February 2007, will return to be the manager of NNSA's Pantex Site Office in Amarillo, Texas.

Established by Congress in 2000, NNSA is a separately organized agency within the U.S. Department of Energy responsible for enhancing national security through the military application of nuclear science. NNSA maintains and enhances the safety, security, reliability and performance of the U.S. nuclear weapons stockpile without nuclear testing; works to reduce global danger from weapons of mass destruction; provides the U.S. Navy with safe and effective nuclear propulsion; and responds to nuclear and radiological emergencies in the United States and abroad.
