Snape the Occlumens

When Harry had to learn Occlumency, it seems as if there were only 
two choices when it came to a teacher:  Dumbledore and Snape.  It's 
no surprise that Dumbledore would know Occlumency, but has it been 
discussed just how Snape knows the skill and is so good at it?  Of 
course, it's very useful for him, but where did HE learn it?  I 
suspect that Dumbledore taught him himself, and AFTER Snape turned 
against Voldemort.  I believe that Snape went to Dumbledore without 
any guarantees of safety or protection, and then Dumbledore 
undertook to teach him Occlumency, in order to keep his treachery 
secret from Voldemort (for his own protection) and enable him to be 
an effective spy.
