I’ve recently had the opportunity to work with Sean on a subdivision. Not only was Sean incredibly knowledgeable about the City’s traffic requirements and code for our project, but he was also able to maintain our tight submittal schedule by providing accurate Traffic Study documents on time that the City was able to approve with their first review. Sean understands the importance of maintaining entitlement schedule as it relates to the overall success of a development project.

I had the pleasure of working with Sean (Kellar Engineering) on the 37th Street Connector Project in Loveland, Colorado. Sean provided traffic-engineering design support to the J-U-B Engineers team, which included roundabout design and a full traffic study for the corridor. Throughout the design process, Sean was responsive, supportive, and provided common sense solutions. I would highly recommend Kellar Engineering for traffic engineering and project management.
