Sean and Kellar Engineering are a great asset to any development team. They are efficient and professional in coordinating the many technical submittals and reports, and also willing to work through the small intricacies and conflicts encountered to provide the best product and value to the end client.
Sean is a dependable and reliable traffic engineer. He has met our project deadlines and has had good relationships with municipalities in northern Colorado while working on our projects. AGPROfessionals would recommend Kellar Engineering for traffic impact studies and traffic engineering services.
After an initial drawing review for one of our church projects in Arizona, we received a comment that required us to provide a Traffic Impact Study before we would be given building approval. While the project timeframe was aggressive and needed to be re-submitted as soon as possible, we quickly searched for an engineer who could help us out. Sean Kellar was one of the engineers contacted, and he turned out to be a truly remarkable find. His quick response and knowledge on the subject made for a smooth re-submittal. While traffic impact studies can often become long and costly tasks, Sean informed us about alternative options that we may look to explore before going down the route of performing a full study. From Sean’s recommendation, we decided to provide a Traffic Impact Statement instead, which led the client to save a substantial portion on time and fees in doing so. Sean’s honest character, knowledge and efficiency in his area of work is invaluable and I look forward to using his services for any future needs.

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.
