**★★★★★ — April Kim, April 2017**

> Mr. Hanna provided plans for my client rapidly and accurately.  He enabled our building process time to be completed in shorter days than expected because of his rapid response.  My continuing future clients with him.  I'm very pleased.

**★★★★★ — Lannie Bade, April 2017**

> I had a pleasure to work with Mr. Hanna. He is very nice, polite, honest and professional.  He did my structural foundation plan for an master bedroom addition. After I received the plan, I went to the city to get an approval but needs some revision. City engineer talked to Mr. Hanna, for less than 2 hours the revision has been done. City engineer called me telling me that I need to go back to the city because the plan is already approved. I will definitely use this company for my future project and will recommend to my friend and family.
