Company History

Cullum has been part of the Southeast service and construction scene since 1972. The company began with small commercial projects and expanded to handle large, technical work. Operations are divided into two segments to separate construction from ongoing service. Over the decades, Cullum has worked on healthcare facilities, laboratories, sports complexes, and manufacturing plants.

Projects have ranged from 2,000-square-foot computer rooms to complex 600,000-square-foot diagnostic and treatment centers. That range helped the company develop skills in medical gas piping and process piping as well as routine HVAC and plumbing.

Leadership

Longtime industry leaders run Cullum’s local operations. The leadership team brings decades of hands-on experience in mechanical systems and project management. Managers live and work in the Greenville area and maintain relationships with local contractors, suppliers, and facility teams.

The company stays involved with local industry groups and training programs. That keeps crews up to date with codes, safety practices, and new installation methods tailored to the humid summers and mild winters of the Upstate.
