William Lewis isn't at v4p any more (that reminds me, must update FHB on that for her list). He's now back at Orchid in Brentwood, although I think he might be on leave this week.
Sam at v4p Braintree is great, she's my vet, also Katherine who is there on a thurs/fri. Ben at Colne Vally Vets in Colchester has some fans as does a vet called Jackie who works there and at Penrose part time - but I don't have personal experience of either.
