If you hadn't noticed already the title is an anagram. Here is a few, feel free to add others that you might have thought up.

OLLIVANDER
AN EVIL LORD

SEVERUS SNAPE
SAVE PURENESS
PERSEUS EVANS
(Also there is this. VEREN PESUSSA. It is finnish and means about the same as "Cleaning Blood".)

ARTHUR WEASLEY
WE SALUTE HARRY

DOLORES UMBRIDGE
GO SIR DUMBLEDORE
GOD REBUILDS ROME

ABERFOTRH DUMBLEDORE
DOUBLE FRAMED BROTHER

PURGE AND DOWSE LTD
DADS LEG, WOUND SERPENT
(If I recall right Purge and Dowse LTD was the false front of St. Mungo's. It would be fitting, but there is an N missing from the name.)

RONALD WEASLEY
SLAYER O' WALDEN
(Slayer of Walden. Walden McNair was the executioner in POA and was later in GOF revealed to be a Deatheater.)

MUNGO
NO GUM

DROOBLES BEST BLOWING GUM
ST.MUNGOS BELOW GOLD BRIBE

(Now these two are interesting anagrams. Remember Alice Longbottom giving Neville gumwrappers? Perhaps she was trying to hint that someone kept bribing St.Mungo's to prevent them to recover and return to the Order? Now if you remember that meeting that was held between Fudge and Lucius Malfoy. Malfoy had donated quite a sum for St.Mungo's. Think about it.)
