The company name – ‘Doorisopen’ is a revelation received by the Managing Director in 1992 when he was praying for the will of God. The company took off in November, 2003 with its office first at Olusosun Shopping Complex before it was later moved to Odua International Model Market, first in Block 22, Suite 4 and then later expanded to Block 20, Suite 9, 10 & 11,  Ojota Lagos. Since then, the company has been registered as a supplier to various companies in Nigeria.

The Managing Director/Chairman has a very wide knowledge as far as the marketing of mechanical power transmission products is concerned, having worked successfully with 3 major companies which has at one time or the other represented Fenner Power Transmission Plc UK for the period of about 15years. The knowledge he acquired during those years have actually spelt him out as one of the best experts today as far as supply of the products is concerned. Where others have failed, because of the products scarcity, he is always available to solve any problems that may occur in this regards.

At the moment, Doorisopen Nigeria Limited has been appointed as a sole agent of Hong's Belt International (HK) Limited to represent West Africa and Challenge Power Transmission (SA) Limited to represent them in Nigeria.
