Our History

Edward M. Twining Jr.’s great-grandfather, Frederick E. Twining (Fred), came to Fresno in 1898 and established Cutter Laboratories. For a number of years following the lab’s establishment, Twining served as State Sanitary Inspector as well as the City Bacteriologist for Fresno. The company focused on chemistry and the production of pesticides to support the agricultural market in central California. Due to two devastating earthquakes and Fred Twining’s subsequent response to enter the construction materials testing market, the company evolved into a testing laboratory.

With its slogan “We Test Anything,” Twining Laboratories became a leader in scientific investigations. The laboratory was involved in vaccine testing for cattle, sobriety testing, and food and drug testing.

Edward M. Twining Sr. founded Twining Laboratories of Southern California. The company’s specific purpose was to engage in the business of operating and conducting a commercial laboratory business. Generally, the purpose was to determine, by scientific investigation, study, experiments, and tests, the properties, structures, component parts, and compositions of various materials, devices, constructions, and soils and to ascertain and define classifications and specifications for materials, devices, constructions, and soils, particularly in the field of general construction. In addition, to build, erect, purchase, lease, operate, and maintain laboratories, testing stations, depots, machinery, and apparatus; to acquire, hold, and dispose of real estate and improvements thereon necessary for such purposes, wherever situated; to finance and subsidize scientific research and investigation in this and related fields.

Twining Laboratories of Southern California was incorporated. The corporate office is located at 1635 W. Gaylord St., Long Beach, CA.

A Corporate Office is Established

They also begin to offer third-party testing and field evaluations for commercial/industrial gas systems, as well as field evaluations for dealers of modified vehicles dedicated to improving the lives of people with disabilities.
