David R. Klemm, owner of Klemm Real Estate in Washington, has announced the agency's expansion.

Klemm, founded in 1982, recently purchased Tierney Realty, Inc. and opened an office in Roxbury.

"Local relationships in our communities have distinguished both firms," said Wayne Piskura, former owner of Tierney Realty.

Tierney was founded in 1967 by Ed Tierney.

Mr. Klemm and his family members, Carolyn, Peter and Graham, have lived in Litchfield County for more than 30 years.

"Through the years we have enjoyed a wonderful relationship with the Tierney people and look forward to many years of expanded real estate marketing and service for sellers and buyers," Ms. Klemm said.
