get just the group user is a member of

I need to get just the groups a user is a member of from AD.  I've tried a few things like this:

(get-aduser USERNAME -Properties*).MemberOf
(GET-ADUSER–Identity USERNAME –Properties MemberOf | Select-Object MemberOf).MemberOf

but both return the full path, example:

CN=*Acme - Recipients,OU=Distribution Lists,OU=Slatter,DC=acme,DC=org

I only want to capture the *Acme - Recipients and nothing else.

Thank you.
