Of course, no expansion is complete without leadership. ES&S is also excited to announce the addition of Dan Rahn, PE to our management team. Dan, a lifelong St. Louisan, will manage our newest location and has 13 years of Civil Engineering experience serving clients both public and private. Dan is a Licensed Professional Engineer and Certified Floodplain Manager with project experience in transportation enhancements, storm water management and flood control, the design of wastewater and potable water systems, and commercial site design He also has extensive experience seeing his projects constructed, often performing field surveying, materials testing, and construction inspection services.
“Unlike many civil engineers, I have had the privilege to work on so many aspects of a project’s life. This experience has given me both a breadth and depth of knowledge that allows me to really anticipate my client’s needs. I’m a Golden Rule follower – treat others like I want to be treated – my experience serving both the public and private sectors has reinforced this belief and strengthens my commitment to serving my clients.” |
Dan is no stranger to ES&S, his first foray into the engineering field was almost 15 years ago as a college intern at ES&S’ Jefferson City office. He spent the summer learning and working in the materials lab and in the field.
“The idea of hard work is something that was instilled in me by my parents. I learned a lot about applying this idea that summer at ES&S, working long, hot days making and breaking concrete cylinders and taking soil samples. But, the biggest takeaway that has really stuck with me was the pride and care that the other field technicians took in acquiring samples, performing the tests and maintaining the equipment. I have used this as a basis for my work throughout my career and have found these values to be ingrained in the culture at every level of ES&S. It feels good to return to the place where it all started for me.” |
Dan lives in Wildwood with his wife Katie and their two sons, Jack and Will. He serves several civic organizations: as a board member of the Meramec River Recreation Association, vice-president of the Pacific Partnership - a downtown Pacific revitalization organization and is involved professionally with the Missouri Floodplain and Stormwater Managers Association.
He enjoys coaching baseball and soccer, spending time with his family at Table Rock Lake, and has a passion for cooking.
