Linde-Griffith Construction Company’s origins date back to 1865 with the founding of The A. E. Sanford Company. In 1909, Linde and George Griffith, then superintendents for The A. E. Sanford Company, purchased The A.E. Sanford Companies assets – the legend has it for the grand total of one dollar!

As the business grew, Linde and Griffith hired Raymond A. Finley, Sr., P.E. in 1921 who had a demonstrated history of construction competency as he worked on the construction of the Panama Canal. Shortly thereafter Charles E. Ryan was hired.

Linde-Griffith Construction Company hired Peter H. Shannon Sr., P.E. to strengthen the firm’s administration, management, and supervision. The deaths of Mr. Griffith in 1939 and Mr. Ryan in 1942 and the increase in national defense work associated with America’s deepening involvement in World War II resulted in the hiring of Charles Stillman, P.E. in 1943.

Shortly after World War II ended, Raymond A. Finley, Jr., P.E., fresh out of the United States Navy, signed on. William Richtmyre, P.E., another United States Navy veteran, joined in 1948 and Linde-Griffith continued to flourish.

After Mr. Linde’s death in 1960 the young triumvirates of Peter H. Shannon, Sr., Charles Stillman, and Raymond A. Finley, Jr. assumed increased responsibility and management under the expertise of chief executive officer Raymond A. Finley, Sr. until his death in 1965.

Peter H. Shannon, Jr. joined Linde-Griffith Construction Company as an operations manager. Four years later, another Shannon son, John F., graduated from Lafayette College and was recruited as a civil engineer and project superintendent. Eighteen months later, Linde-Griffith Construction Company hired a third generation Finley, Raymond A, III, as the office manager.

With Charles Stillman’s phasing into retirement in 1971, William C. Richtmyre and Peter H. Shannon, Jr. were called upon to lead Linde-Griffith.. Nine years later, in 1980, Raymond A. Finley, III and John F. Shannon, P.E. became stockholders. With the retirement of William Richtmyre in 1984, Linde-Griffith Construction Company’s path of excellence was tended by five experienced individuals: Peter H. Shannon, Sr., Raymond A. Finley, Jr., Peter H. Shannon, Jr., Raymond A. Finley, III, and John F. Shannon.

Approximately eighteen years passed before the third generation of Shannon's and another third generation Finley joined Linde-Griffith Construction Company. Christopher Shannon, John D. Shannon, David Price (in-law), Kevin Shannon, and Michael Shannon now supervise all company operations as company shareholders. In 2021, Peter Shannon, the fourth generation of Shannon’s to work at Linde-Griffith, became a stockholder in the company as Linde-Griffith continues to expand.
