2023 40 Under 40: Benjamin Olejniczak, PE, 32
Senior Project Engineer, ESD; BS, Mechanical Engineering, Valparaiso University
Olejniczak joined ESD after completing an internship program with the company and became a staff engineer. He quickly advanced, first serving as a project engineer and then as the de facto mechanical lead for ESD’s largest client. His combination of design, work ethic and credibility with clients has positioned him as a key leader for one of the company’s largest hyperscale data center clients. When a client challenge arises, he first addresses client needs, then performs research and engages others with unique experience to gain insight before crafting an informed solution. His dedication, creativity and personal integrity are all highly valued qualities appreciated by clients and colleagues alike. This high degree of professionalism was recognized by ESD in May 2022 when he became an inaugural recipient of the ESD Leadership Award. Olejniczak is also dedicated to fostering the next generation of building professionals. In 2019, he volunteered with the Chicago Architecture Center’s Engineering Festival. He also is generous with the time he dedicates to professional organizations such as ASHRAE. He is an active thought leader, publishing and presenting to professional organizations and peers. Olejniczak has been committed to making a difference in the lives of young people in his community, which he now extends to his three children. He and his wife also enjoy traveling, hiking, exploring new restaurants and spending time with extended family. He also enjoys the solitude of a walk through the woods or an afternoon of fishing, particularly with his two older children.
