Eryn Dietzenbach

Professionally Registered Architect – CDT

As a registered Architect, Eryn has the years of experience it takes to deliver a built project, but it’s her talent in creating color graphic representations of interior and exterior 3-D images and renderings that sets her apart. She loves to help clients arrive at the “ah-ha” moment during the design process where they can see the design come alive. This provides a sense of confidence in the design that just can’t be accomplished through flat black and white drawings. In addition to this, Eryn’s interest and technical approach to color theory, spatial relationships, and general problem solving offer a highly sought after skill set to our team.
