Alamo Investment Co.

Alamo Investment Company (AIC) is a wholly owned subsidiary of The Lineweaver Trust, and is involved in the acquisition, renovation , management and sale of 1-4 family homes, as well as various non-real estate investments.

Over the past four decades, AIC has been involved with small properties in the Contra Costa County communities of Lafayette, Orinda, Danville, Alamo, San Ramon and Brentwood, in the Alameda County communities of Oakland and Piedmont, and in the Northern California communities of Fairfield, Live Oak and Willows.

AIC has also been involved in the ownership of several food service businesses, including Coldstone Creamery franchises in Clayton and Vacaville, and Vitality Bowl franchises in Pleasant Hill and San Francisco.
AIC also managed The Lineweaver Trust’s interest in Table Mountain Quarry in Oroville, CA. Table Mountain Quarry, previously known as Green Rock Quarry, was established in 1987 on several hundred acres of leased land near Oroville. The owners successfully endured a multi-year battle to obtain a Mining Permit, and developed a full-service rock quarry, complete with a railroad spur, crushing equipment, and a fleet of tractors, loaders and trucks. The Lineweaver Trust sold its interest in 1993, while retaining royalty rights.
From 1986-1993, AIC was also involved in a textile manufacturing and importing business in mainland China, designing, manufacturing and importing handmade Amish-design quilts, in a venture named Unique Quilts, Inc. After making several dozen trips to and from China, AIC owner John Lineweaver sold its interest in the venture in 1993.
