After nearly 20 years of dedicated service, TPD congratulates Doug Stumpp on his retirement and celebrates the lasting impact he has made on our firm, our clients, and the transportation industry.
Doug joined TPD in 2005 and quickly became a driving force behind the growth and success of the firm’s Structures Department. Throughout his career, he demonstrated exceptional leadership, technical expertise, and an unwavering commitment to quality that helped shape TPD into the organization it is today.
One of Doug’s most significant contributions was establishing TPD’s NBIS Inspection Team and guiding its growth into a highly respected, multi-district operation serving PennDOT Central Office, numerous PennDOT districts, and county and municipal clients throughout the region. He also played an integral role in developing the firm’s quality assurance and quality control practices, implementing systems that continue to support project delivery across the company.


Beyond his technical accomplishments, Doug has been a trusted mentor to generations of engineers and inspectors. His steady leadership, attention to detail, and willingness to share his knowledge have helped develop countless professionals throughout his career.
Although Doug is retiring from TPD, his passion for engineering and education continues through his long-standing involvement with Messiah University, where he teaches and mentors future engineers.
Doug’s contributions have left a lasting mark on TPD, and his legacy will continue to be reflected in the people, processes, and culture he helped build. We are grateful for his years of service and wish him all the best in his well-earned retirement.
