Over 65 firms have responded to ENR California’s annual Top Design Firms survey. This regional survey, which you can find here, has an extended deadline of March 29, 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 print edition of ENR California and Northwest.

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.
