Meet Our Team!

Chief operating officer Randy J. Long, founder John A. Long, office manager Linda C. Long, and cad designer Ryan M. Long.

J.A. Long, Inc. has built a stellar reputation as a master builder for some of northeast Florida’s best residential custom homes.

Founded by John A. Long in 1972, J.A. Long is a family-owned company that is driven by its commitment to quality, personalized service and creating some of the most beautiful homes in North Florida.

By focusing on delivering a quality product, the firm has built a reputation for real dollar value and solid craftsmanship. These high standards are made possible by the family’s personal involvement in every project from the original design work to the daily on-site supervision.

These standards are also backed up by the J.A. Long “Extended Care” policy that goes well beyond the written warranty.

John A. Long

Chief Executive Officer

Since he once served as a naval aviator, it’s no wonder that company founder John A. Long would end up living and working in the largest Navy town in the southeast.

Born and raised in eastern Pennsylvania, John attended Muhlenberg College and received a Bachelor of Liberal Arts Degree before joining the U.S. Navy in 1967. After completing Aviation Officer Candidate School, John was a designated naval aviator – piloting A-7 jets until he left the service in 1971.

After he left the service, John initially worked as a stockbroker for Dean Whitter, and then decided to go an entirely different direction. As he searched for his next career, he worked as an installer for a national retailer in the home building industry. It was then that he discovered his passion for home building.

Marrying his wife Linda in 1970, John launched J.A. Long, Inc. in 1972 – building the company’s first home in Green Cove Springs. Since that time, John has built an excellent reputation for his creativity in designing some of the most unique and functional custom homes in Jacksonville.

In addition to his business, John has given back to the community in a variety of ways. He has served as a member of the Clay County Board of Adjustment and has been active with the Northeast Florida Homebuilders Association. John and his wife also assist in various outreach projects throughout Clay County, including fundraising for the Clay County Children’s Center.
