"I was in serious need of a top structural engineer to evaluate exterior remodeling on my home. Previously I hired someone representing themselves as a contractor to complete some comprehensive work on my home. The individual quit before the work was complete, leaving me figure out the rest. After finding out this person wasn't actually licensed in the first place, I desperately needed a structural engineer to assist me. The amount of work to review was substantial, and I had a very difficult time finding a structural engineer. After submitting a request on Angi, Neal from R4 Engineering reached out to me. From beginning to end, he was kind, professional, and thorough. He scheduled a meeting with me in a very reasonable timeframe. After coming to my home, discussing the work in depth, and taking lots of photos, a report was compiled. I needed a report that served multiple purposes. I needed data to address the fraudulent contractors work, a clear road map to provide a licensed contractor for correction of the remodeling, and plans to provide the county for permitting purposes. When I received the report from Neal, I was truly blown away at detail. Only someone who takes pride in their work could assemble a report like this. The amount of hours and effort that must have gone into this is rather remarkable. Neal and R4 will definitely be my go to for structural engineering from now on."

"I hired them to create plans for an apartment building. The process was quick and painless. Cost was good. The plans are full complete abd ready to take to builders for quotes. I will definitly use them again."

"Mark was great! He was very thorough and helped us identify what most critically needed to be addressed in our home. Having him offer a neutral 3rd party opinion helped ease our minds regarding the various projects that need to be completed. Highly recommend."

"I decided not to pursue a design project. I bought a builder designed home but appreciated the consultation offered by Kippenberger."
