"Great ! Owner Tim came out and did an emergency tarp -- in the rain, as my BR ceiling was leaking. Jan ( office manager ) worked with my insurance until the bid & repairs were enough to give me a great outcome. Their repair guy was professional, friendly and did a good job. I would not hesitate to use them again & to recommend them !"

"Aaron was very knowledgeable and turned around drawings in only a few days time to meet my tight project schedule. I will recommend him to anyone needing a structural engineer in the future."

"Our relationship with Tim was an exceptional one. We live in a house he designed, can not find any problems with it, he did a great job. The plans exceeded our expectations."

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"
