"We are builders and have been building in central Ohio for over 25 years. We are thankful to have known Dave. He is extremely knowledgeable, communicates detals in an easy way and is very prompt to deliver. He often finds other ways to engineer things that we hadnt considered which make him our 1st choice in engineers. We would highly reccommend him and his services."

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

"Evolution Drafting did a great job modifying my existing plans and updating for Arizona codes and took care of the structural engineering as well."

"Jeff was excellent to work with! He was knowledgable all of the details, manufacturers, colors, and came up with 4 different design options for the exterior of our home. We are just regular people, with an average home, who are planning to replace roof, trim and accent siding. His fees are reasonable, and totally worth it for such a big investment on our home. More people should consider getting some help with these important decisions. Thanks again Jeff!"

"We needed someone to go through the city variance process for our build. In the middle of the process our original architect was unable to finish our project and Tate Architectural Design was able to pick up where we left off and complete the job. They were also very easy to reach and helped us every step of the way with any questions we had. I would highly recommend."
