"Stan Hayes, P.E., and Hayes Engineering, Inc. have provided professional services, as well as been a valued friend for many years. My experience with them the past 4 years that I have been in office has been great. The first week I was on the job, Stan and Kyle Stephens, P.E., met with me and updated me on the current projects. Since then they have always been available to walk me through each project and explain how things work and answered any question I may have. Hayes Engineering has provided personal service to our community with the utmost integrity. We look forward to many more years working together to improve the City of Hallsville."
