Soon after, he started working in Los Angeles with a local Orthodontist named Dr. Ray Robinson.
Orthodontic schools of the era spent much time in maintenance of the primitive appliances then in use, often repairing and re-cementing bands owing to the crude nature of early materials and adhesives.
He eventually went to Pasadena, California to meet and enroll himself in the nascent Angle School of Orthodontia.
He worked at the Angle School of Orthodontia, perfecting the edgewise bracket, and associated armamentaria, that would become the standard of care in orthodontics for the next century.
The Department at USC dedicated their library to Dr. Steiner in recognition of his significant contributions to the school.
