Miles E. “Budd” Cullom, Jr. 


During his long tenure in the development industry, Budd Cullom has seen his share of zoning battles and has successfully completed ventures the average developer would think impossible.


The Knoxville, Tennessee native worked in his family’s concrete business and skipped college to pursue a real estate license. After selling houses for a brief time, he transitioned to commercial real estate in 1983. He started his own company at 21 years old. A year later, he joined a competitor where he worked until starting Cullom Properties in 1991.


Cullom doesn’t have a college degree, but he has moved a mountain. In the early 2000s while developing a shopping center for Walmart and Lowe’s in Hazard, Kentucky, he had to move three million cubic yards of solid rock with a coal seam to accommodate the retail center.


His portfolio reflects his dogged personality and includes projects in 10 states across the South and Midwest. His client roster includes Publix, Walmart, Target, Home Depot, Lowe’s, Kroger, Walgreens.


Cullom serves on the board of Coal Creek Company. He is a former board member of Cherokee Country Club, the Helen Ross McNabb Foundation and St. Mary’s Foundation (now Trinity Foundation).
