History of becoming a strong technology partner for our clients

J4 Corporate offices

J4 Systems started in 1994 and initially we offered basic networking services to businesses in the Sacramento region. Since then we have added 45 talented professionals and opened a branch office in Stockton toward our efforts of becoming the leading technology company servicing all of Northern California.

We work closely with our clients to become a valuable business partner to assist in the strengthening and growth of their company. Our employees care deeply about the success of our clients and take their relationship with them very seriously.

Today our services include network infrastructure design and implementation, custom software development, training, data/telecom analysis, and hardware and software sales.
