While our projects span size, market segments and budget, the common thread is our ability to uncover and explore to tell your story through architecture and design.

And we absolutely love it!

Founded by architect, Jana Itzen (in 2011), ITZEN is led by the husband and wife team of William and Jana. Prior to starting ITZEN, both architects spent over 10 years contributing to significant projects at firms local to Southern California and abroad.

ITZEN Architects, Inc. is a full service architecture design firm rooted in the heart of Santa Ana, California. We are focused on creative collaboration throughout each stage of a project and believe your architecture should be thoughtful, exciting, forward thinking and FUN.
