As of March 23, more than 75 firms have responded to ENR California’s annual Top Design Firms survey. This regional survey, which you can find here, will remain open until at least April 1, so there is still time for any design firms working in California or Hawaii to take part. The resulting California Top Design Firms ranking will appear in the May 25 print edition of ENR California and Northwest. To participate in other regional Top Design Firms surveys, readers can click here.

Below you’ll find our preview of this year's respondents to date. An important note: Because of space limitations for the print edition, it’s possible that firms listed here may not be included in the print ranking as a result of their revenue totals. CPP---Student-Services-Buildng
