Our company was established under the name of OK-EL Elektrik in 1996, with partnership of Osman Özsoy and Kenan Özsoy brothers.
Standing out with their electricity contracting and subcontracting services under the name of OK-EL, Özsoy brothers did not leave Kocaeli despite the great destruction caused by the 1999 Marmara earthquake. They successfully completed all the electrical works assigned to them in the new construction of the region, and in a short time they became a recognized and preferred position in Kocaeli and the region.
After about 8 years of OK-EL electricity period, in 2004, with the participation of the third partner of the company, Electrical Engineer İsmail Birer, our company changed its name and continued its services under the name of "Birsoy Mühendislik Elk. Tah. San. Tic.".
