About our company

At DENNIS, we’ve earned the right to call ourselves the uniform experts! We’ve spent nearly a century designing uniforms and uniform programs in Portland, Oregon, USA. Proudly serving more than 2,000 top schools across the nation, we are much more than an outfitter – we forge lasting partnerships that benefit schools and families.



Our history

Founded in 1920, we got our start manufacturing nursing uniforms and even supplied apparel and linens to military personnel shipping out of the Port of Portland during World War II.


After the war’s end we created our first line of school uniform apparel, including our first plaid. By 1951 we opened our first retail store, and over the ensuing years our business kept growing. Now we’re proud to serve schools all across the United States!

Still making things by hand

While we offer hundreds of styles from a variety of carefully monitored sourcing partners, we’re especially proud to manufacture our signature collection by hand in our union factory. Manufacturing locally has many benefits, from supporting the local economy to helping us control the quality and timely delivery of our garments.


Responsible manufacturing

We put our hearts into our DENNIS products, starting with perfecting their fit and design in-house. Whether a uniform is made at our Portland factory or sourced from carefully chosen and monitored partners, we use domestically made fabric whenever possible, and ensure all our partners meet the strictest standards for working conditions and fair labor practices.



Partnering with our schools

Uniforms are just the beginning! At DENNIS, we partner with our schools to support their educational goals. We work closely with school administration to provide fundraising assistance, sponsorships, and uniform scholarships for families in need.
