What has been your most rewarding moment or contribution to the Civil Engineering profession?

During the design of a stormwater facility, neighbors stated how stormwater would flood through their front door and go out their backdoor and how stressful it was that they were scared to leave town during the summer because of damaging rainfall events. Following the implementation of the project and the first large rainstorm, the neighbors were so thankful to the municipality and designers because their homes didn’t flood and it was such a relief to them!

What is your favorite thing to do in your free time, when you’re not working or volunteering for ASCE and other organizations?

I enjoy coaching and watching my kid’s various sporting events. We also spend time as a family up in Door County and Lake Geneva, Wisconsin.

What is one piece of advice you would give to Student or Younger Members as they start their careers in civil engineering?

Get outside and see how projects are actually built! It will open your mind as a planner and designer and help you be better at your job!
