Guilder Opened in April 2017 by Caryn & Mike Nelson along with partners Toby Roberts and Carrie Lind.

The first location opened in the alameda-irvington neighborhood of northeast Portland. They then opened Guilder cafe inside Powell’s city of books in November 2021. They then opened a cafe under roasting brand, Junior’s Roasted Coffee, in 2023. It is co-located with Upright brewing’s taproom in the Cully neighborhood.

In 2023 the group decided it was time to hand the business to new owners. In April 2024 Ryan Willbur & Laila Ghambari took over ownership of Guilder Cafe & Juniors Roasted Coffee. Both are Specialty Coffee veterans born and raised in the PWN. They are excited to continue the work that Mike and Caryn started and bring it to and even larger audience.
