American Sentinel U merges with Post University

[Alpha]

I'd just write it as "American Sentinel College".

The way I'm reading the announcement it seems as thought American Sentinel is going to becoming a college within Post University.  For example, you can say that you attended the Kellogg School of Management but that is a part of Northwestern University and I believe your diploma would say "Northwestern University" at the top, perhaps including the whole Kellogg thing.  So if you wanted to shorten the name it might be more appropriate to say "My degree is from Post University."
