“…we cannot recommend highly enough BEAR Engineering.  The reason for the 5 out of 5 stars on Yelp over 120 reviews is now very obvious to us how this was accomplished.  A first class operation, through and through.” - Jay C.

“… It is clear that they are experts in the field and can convey their knowledge easily both onsite and in their reports.  I got the clear impression that they are trustworthy and value long-term relationships with their clients." - Brent T.

"...I appreciate that they do not offer contractor services themselves, so I trust his assessment is unbiased" - Mel T.

“…I feel like it's so rare to find someone in this industry that has good communication, is easy to book and organize with, and seems to care about the customer's experience.” - Charlie S.
