John D. Calhoun, Chief Executive Officer, Integrated Management Services (IMS)
Integrated Management Services (IMS) was formed in 1996 by two visionaries who saw the need for an engineering firm focused on the unique needs of urban areas.  John D. Calhoun, Ph.D., and Rod L. Hill, P.E., both former employees of the city of Jackson, now operate a thriving business that offers full-service consulting, engineering, technical, emergency response, construction management and operations assistance to help public and private clients improve their environment and infrastructure.
Today, IMS successfully manages construction projects with values exceeding $1 billion annually.  IMS worked on multiple Gulf Coast rebuilding projects after Hurricane Katrina and secured a $69,560 federal contract in 2010 from the U.S. Department of the Army for general engineering services performed under the American Recovery and Reinvestment Act.  IMS received a $102,000 SBA-guaranteed CAPLine line of credit in 1998 to sustain its early growth, and participated in SBA’s 8(a) business development program to boost procurement opportunities.
The company has grown from a two-person firm in Jackson to a staff of 178 today with additional offices in Greenville, Miss., Memphis, Tenn., New Orleans, and Detroit.  The firm recorded a phenomenal sales growth of 908 percent during its first five years in operation.
