History: One hundred years By James R. Griffin Reposted from the Tri-City Voice article Randolph Adams Griffin (R. A. Griffin), Irvington builder and community leader, retired in 1963 after 50 years in business building custom homes, farm buildings, dairies, churches and whatever needed to be built in Southern Alameda County. His son, Jim, took the reins. He thought: “Fifty years – such a long time!” Another fifty years have gone by and the company, now named “James R. Griffin, Inc.,” is celebrating its 100th anniversary.
