Testimonials

I’ve had the pleasure of working with Sean Kellar at Kellar Engineering on several projects. He is easy to work with, extremely responsive, follows through on his commitments, and is an excellent traffic engineer. I enjoy working with him and wouldn’t hesitate to recommend him for all of your traffic engineering needs including roundabout design.

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.

We have been very impressed in working with Sean over the past decade. He had a very common sense approach through his work at the City of Loveland. The insight and responsiveness that Kellar Engineering contributes adds significant value to our projects.

Alex Hoime, PEDirectorTait & Associates, Inc.

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.

Dan Tuttle, P.E.Project ManagerJ-U-B Engineers, Inc.

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.
