If you are hunting for info on the ultrasound career path, I would advise taking a visit to the site This site is under development
It's a growing entity, and it only lists the accredited schools.
There is a bunch in California I know.
Each page lists the specialties it offers and all the contact info is there to.
Make sure you look only at the accredited schools. Employers won't even talk to you without having gone to one of these schools.
