Shannon Halligan

Chief Executive Officer

Shannon Halligan graduated with a degree in Building Construction from Georgia Tech in 2009. Out of college she started with Turner Construction and had the opportunity to work on multiple projects from start to finish in different industries and a range of sizes. She received on-the-job experience in healthcare, research, higher education, and data center construction. After five years with a large commercial contractor, Shannon was ready for a more hands on project management experience. She found that in Moeller Purcell in March of 2014.

In her time with Moeller Purcell, she has learned that you can be proud of a simple storefront makeover to a multi-phased, high-end finishes office renovation. As long as the client’s needs are met and they are happy in their space at the end of the day, then any project is worth being proud of. Shannon believes Moeller Purcell is so strong at harnessing each individual’s talents to produce successful jobs for top notch clients. That was proven when Shannon made the shift from Project Management to become one of the key leaders at MPCC as the Vice President of Preconstruction in October 2022. After owning the preconstruction department, she was promoted to CEO in July 2024 and will provide a clear vision and direction for the continued success of Moeller Purcell.

Most of Shannon’s weekends are spent exploring all that her community has to offer with her family. Shannon and her husband, Todd, along with their three daughters enjoy spending time at any restaurant with an outdoor patio, riding bikes around the neighborhood, or watching a Braves game. If it’s fall, you can find her in white and gold cheering on the Yellow Jackets.
