I have waited a long time to complete this review. Please stay away from this firm. I have been working with them for 14 months it started out good but has ended horrible. I had to fight with Dale to get the package submitted before year end and when his son finally did it was sent to the wrong department Building and safety.

He also said that the out

When I declined his services, his response was

We needed an hour consultation to get some ideas thrown around. Since we are soon to be remodeling our office space, we decided to receive professional advice on the design and spacing concepts for our new look. We got exactly what we were looking for! The receptionist was sweet, nice, and quickly returned the voicemail I left during their lunch. The architects were on time, full of ideas, and prompt. It didn't hurt that they looked like a couple of "axe-wielding lumberjack", a perfect fit for their specialty. Though we were not building a log cabin of an office (I wish we were
