Its a real school, with multiple campuses across regions, the closest to me is Antioch Los Angeles. As with most private institutions, tuition is pretty high. It appears to be unranked in USNEWS but it is accredited by a regional ranking org (HLC). Looks like it is marketed towards working adults who take afternoon/ night classes. I'd compare it to a state school but since it's private the student faculty ratio is probably lower. If the PhD program provides funding, might be worth looking into! Personally, I do not know anyone who went there. I think if you are looking to work in the region of the campus job prospects will be good due to connections nearby.
