The Leo J. Mahoney Company has been a family owned and operated business since 1963.

However, our heritage in the electrical business actually dates back to 1918 when the namesake of our company, Leo John Mahoney Senior, was the Chief Electrical Inspector for the city of Toledo, Ohio.

Leo J. Mahoney Sr. also aided in the writing of the first National Electrical Codes.

Since then we've grown from a 'Rep' outfit into a stocking distributor.  We are proud to have grown to be the largest independent stocking distributor of Magnum/Connectron products, a division of Cooper / Bussmann.

If you don't see something on this website or on our line card, give us a call and we'll help you find it!
