As CEO, Kelly leads the entire organization which also includes PMO, fiber design, small cell and DAS design as well as construction services. Under Kelly’s leadership, the company underwent a significant financial and cultural transformation, emerging as a thriving powerhouse known for its expertise in program management, world-class execution, and customer solutioning.

In November 2023, Kelly was named Titan 100 – Chicago award winner. The Titan 100 program recognizes Chicago's Top 100 CEO’s & C-level executives as the area’s most accomplished business leaders in their industry using criteria that include demonstrating exceptional leadership, vision, and passion. Shortly after receiving the Titan 100 award, Kelly was deeply honored to have been invited to serve on the Chicago Board for the Titan 100. She feels it’s a tremendous opportunity to contribute to the ongoing growth and prosperity of the Chicago business community and is humbled by the chance to collaborate with fellow leaders.

As a proud mother of two boys and three girls (one daughter is on the Atlanta police force and another daughter preparing to ship out for the Marines in July), Kelly recognizes the unique challenges that women face in the industry.
