I'm not seeing where Lee Dennison Associates has its own website, but there's a page
on ukscreen.com which currently contains the following:
QUOTE
Working alongside Lee in London are Jacquie, Jamie, Will and Dean, in New York Ram, Charlie and Lucy and in Paris Claudine and Luc. We also employ a team of casting assistants for each office who work on specific projects.

WINTER 2009 UPDATE...PLEASE NOTE Lee is unable to enter into any private and personal correspondance. See casting credits for current work including THE COMPANY OF MEN, NEW YORK I LOVE YOU and DEFYING GRAVITY. Lee is now based with Ron in LA.
(Livingston is (or was) one of the stars of
Defying Gravity, basically a soap opera/mystery drama set on a spaceship.)
So if there really is such a company (?), presumably "in New York Ram" would suggest that maybe "Ram Sweet" actually
is a real name, or at least a non-internet pseudonym. If he's one of the people spreading this rumor, or even inserting this info into WP himself, then he's apparently one of Dennison's own colleagues and/or employees, assuming he (or Dennison) even exists at all.
