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.

I’ve had the opportunity to work with Sean over several years and found him thorough and fair handed.  He welcomed innovation while being sensitive to needs of all stakeholders.  I know Sean to be virtuous man and respectable engineer.

I’ve worked with Sean for a number of years and find him to be very knowledgeable and efficient.  He provides solid work at a fair price.  Sean has a valuable knowledge of the development review process which is helpful in keeping projects moving forward.  I definitely recommend using Kellar Engineering for Traffic Impact Studies.

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.

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.

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 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.

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.

I have had the opportunity and pleasure to work with Sean on several projects in the City of Loveland, Colorado.  His transportation experience, engineering judgment and commitment to professionalism really shows in the outstanding quality of his work. I consider Sean to be my most reliable Go-To engineer for excellent advice and thoughtful opinions.

Sean has been a very professional and helpful engineer to work with, both as a City engineer and as a consultant.  Sean is committed to great customer service and completes high quality work.  I highly recommend him for your transportation needs.
