Welcome to San Joaquin Delta College Purchasing Department.  The primary responsibility for the procurement of all supplies, equipment and services for San Joaquin Delta College has been delegated by the District’s Board of Trustees to a centralized Purchasing Department.

All procedures are designed to conform with the laws of the State of California and the policies and regulations established by the Board of Trustees to assure that purchases are property authorized and result in quality goods or services being delivered to the designated locations at the appropriate time, in the right quantity, and at the lower possible cost.

The purchasing staff is expected to conduct themselves in a courteous, ethical and professional manner; to maintain good relations with faculty and staff, to grant all competitive vendors equal consideration; to regard each transaction on its’ own merits; and to foster and promote fair, ethical and legal trade practices.

All persons with budget responsibility can simplify and expedite the handling of requirements by becoming familiar with the District’s procurement policies and procedures.  Responsibility for implementing the following procedures rests with the Purchasing Department; the cooperation of faculty and staff is appreciated.  Suggestions for improvement are always welcome.

Should you have any questions, please feel free to contact me at (209) 954-5065 or via e-mail at

Maria G. Bernardino
Director of Purchasing
