In my over 20-year career at Ayres, I have enjoyed the challenges I've experienced along the path to my current position of manager of the structures group. Ayres is a great place to work. I appreciate that the company values me and my efforts to make projects and the company successful. Everyone is conscientious and committed toward a common goal.
My responsibilities within that pursuit of successful projects for our clients include project management and engineering for highway and pedestrian bridges, buildings, dams, retaining walls, tunnels, existing structure assessments and renovations, and structural repairs. My bridge experience includes long-span bridges, curved bridges, and highly skewed bridges. I've designed hundreds of bridge replacements and rehabilitations, most of which have been Wisconsin Department of Transportation (WisDOT) projects. I've worked on structures in nearly all Wisconsin counties and in 10 states.
My experience on large projects and my consistent attention to detail mean I deliver solid structural engineering on projects including:
- Highway and pedestrian bridges
- Buildings
- Dams
- Retaining walls
- Tunnels
- Structure assessments, renovations, and repairs
