Sean joined us in 2010. On January 1, 2013 he became a key Principal who now leads or co-leads system design for most of our largest projects. He also leads our work for system design drawings, mechanical engineering, and special CA services. Since 2010 he has been involved in most of our building projects over 100 stories, such as PNB118 in Kuala Lumpur and World One in Mumbai; also a large airport in KSA, the Miami Science Museum, various office towers including TD Ameritrade HQ in Omaha and Reforma 432 in Mexico City. He is currently leading our work for the Hudson's Site in Detroit, was a key contributor to our studies of the existing lifts at the world's tallest building, Burj Khalifa, and has led many of our traffic studies and simulations for complex "wide-rise" projects.

Earlier, Sean was Design Department Manager at Lerch Bates Elevator Consulting HQ, where he was responsible for leading design services for projects in the USA, and several international projects. He has designed elevator, escalator, and moving walk applications under many regional USA and international codes, and worked on a wide range of projects from tall/high-rise projects such as the Trump Tower Chicago (1362ft, 415m), to airports such as the Las Vegas Terminal T3, convention centers & stadiums like the Doha Qatar Convention Center, Georgia USA Gift Mart, and Charlotte Arena, to custom elevators for the LA County Museum of Art – BCAM.


Like other key consultants in our technical team, Sean was also involved in the engineering of elevator products, in his case with Kone Montgomery where he supplied mechanical engineering designs, drawings, and materials lists for custom traction and hydraulic elevators for manufacturing and installation. In this role he also worked with architectural, structural, manufacturing, and field teams throughout the product design and installation process; and provided product and process improvements, and helped train, mentor, and check work for new engineers. This experience has been taken to a new level with us in provding solutions now followed by many manufacturers.


His advanced studies with us cover rope resonance for tall travel shuttle lifts to determine parking and opening locations, a regenerative power study for an evacuation mode to confirm advantages for emergency power, studies of drive power vs. enery consumption, and he co-authored our study of elevator safety devices going beyond current codes. Sean also holds a BS in Mechanical Engineering and is a Licensed Professional Engineer (P.E.).
