Where can I find a list of apprenticeship program sponsors? 

Employers

Apprenticeship program sponsors administer and operate an apprenticeship program. To find sponsors in your area, or sponsors specialized in your desired occupation or industry, search Partner Finder on Apprenticeship.gov under Resources. 

The Partner Finder offers several options to find sponsors including the ability to search by need, organization name, and by state/county. When on the search by need tab, check the box labeled "I want to learn from sponsors" to view sponsors.
