College Graduation Announcement (When you aren’t going to attend Graduation)?

I’m finishing my graduation requirements for my Associate’s degree in December. My college only has one graduation ceremony in May, which includes and entire year of graduating students. Since I will be finished in December I will be going into the work force I don’t really plan on attending the ceremony in May but I want to announce to my family and friends that I have graduated. How should I word the announcement? I don’t want to brag but that’s what an announcement basically is anyway. So how should I include my collegiate achievements into the graduation “announcement”? I’ve thrown around a lot of ideas but I just can’t decide what to do. Thanks so much for your time!
