ENR Texas & Louisiana’s 2023 class of Top Young Professional features an impressive collection of current and future leaders who are helping their respective firms improve their bottom lines and expand opportunities. Diversity, equity and inclusion is a theme throughout, as this generation of AEC professionals ensures that their firms—and the industry a large—are representative of the communities they serve and support. Many are also engaged in expanding the use of technology and setting standards for quality in the industry.
The annual awards honor 20 individuals in each of ENR’s 10 regions. Firms from Arkansas, Louisiana, Mississippi, Oklahoma and Texas submitted 64 entries into ENR Texas & Louisiana’s contest. These individuals were then judged by three primary criteria: industry experience and education; career and industry leadership; and community service and involvement.
A team of independent industry judges was split into sections to tackle the numerous entries and did not score any applicants with whom there could have been a conflict of interest. This year’s judging panel included: Kristi Grizzle Gollwitzer, urban development project director, Houston First Corp.; Alex Morales, senior structural steel specialist, American Institute of Steel Construction; Claire Obgartel, vice president, workforce development, ABC New Orleans/Bayou Chapter; Erin Peavey, architect and design researcher, HKS; Hossein Roshani, project manager, Lockwood, Andrews & Newnam Inc.; Todd Wynne, chief innovation officer, Rogers-O’Brien Construction; and Chad Yount, area manager, Sundt Construction.
Congratulations to regional winner Jennifer Sloan Ziegler, engineer and project manager at Cypress Environment & Infrastructure in Ocean Springs, Miss., for being selected as one of ENR’s national 2023 Top 20 Under 40 cohort. ENR will recognize her at the Top Young Professionals Conference on March 8-10 in New Orleans. For more information, visit https://www.enr.com/top-young-professionals-conference.
