OUR BEGINNINGS.

Since its founding in 1980, Duringer Orthodontic Laboratory has been built on a single, unwavering principle: quality above all. Kathleen Ryan established the lab with a vision to deliver exceptional orthodontic appliances, and today, that standard continues to define us. As we have grown to support practices across the Bay Area and throughout California, our dedication to excellence remains as strong as ever.

OUR PRESENT.

The Duringer family continues to grow stronger. Based in Alameda, California, our team of skilled specialists partners with dozens of practices throughout the Bay Area, producing a diverse range of orthodontic appliances with unmatched quality. As demand for our work continues to rise, we are focused on expanding our reach and building new partnerships with practices beyond our current network. With confidence in our craft and faith in the future, we are stepping into the next chapter of growth with excitement and vision.
