PROtech Security & Electronics, Inc. was founded in 2002 by Modesto native Dimitri Guzman as a division of Bestco Electric, Inc. dba Best Electric. The purpose was to provide a more responsive level of service the electronic security industry was lacking from an established Electrical Contractor’s perspective. Due to the tremendous growth of PROtech, the division became a separate company incorporating in 2007. Currently, PROtech Security & Electronics, Inc. has branch locations in both Modesto and Merced California.
