DENNIS 101: One Hundred and One Years of Success

November 18, 2021

For 101 years, DENNIS has been leading the school uniform industry with top quality product and best-in-class service. To celebrate our 101-year anniversary, we thought we would give you an overview of who we are and what we do today, as the nation's largest and leading school uniform provider. 

A Quick Timeline


 From humble beginnings as a manufacturer making nursing uniforms in 1920, we still own and operate out of that very same factory in Portland, Oregon. 


Shifting our focus to serve the war effort during WWII, we supplied linens and apparel to military personnel shipping out of the Port of Portland.


After the war’s end, we created our first line of school uniforms, including our very first plaid. We opened our first retail uniform store in 1951.


With 35+ retail stores nationwide and an online store open 24/7, we are the #1 school uniform provider in the USA serving over 2,000 schools and outfitting half a million students every year.

Modern Classic: Comfort & Durability

Your favorite uniform pieces have been refreshed for the times. The most sought-after style in fashion, modern classic doesn’t bother itself with fads. Instead, we focus on fresh, contemporary looks that still maintain the heritage craftsmanship of a traditional school uniform. Easy fitting and easy care, with simple lines and clean cuts, our tailored pieces are made so comfortable that they move with the most active kids, and so durable that they wear them until the garment is worn out. 

Moral Fiber: Responsible Sourcing & Environmental Stewardship

Fabric sources matter! At DENNIS, we use domestic fabrics whenever possible and ensure all partners meet the strictest standards of working conditions and fair labor practices. We believe sustainable business practices enable sustainable lives. We are increasingly integrating solutions to reduce our footprint and our impact on local, national and global environments, and we maintain exceptionally lean supply chains to minimize our manufacturing and environmental footprint.   

Giving Families The Value They Deserve

At DENNIS we pay attention to the prices of all our competitors, making sure that we are always offering school families their uniforms at a fair price. School families can rest assured that their top-quality items are offered at a consistent price all year long, with an occasional promotional event. Families can subscribe to DENNIS emails anywhere on our website to ensure they never miss a sale!
