I did a search for Lisa Gerstel but only 1 search came up which was a german unrelated search.I couldnt find her name on the Disney executives list.Even in the Disney company information, there is very little reference to the muppets holding company.I rang Disney and asked to be put through to the Muppets holding company and I got put through to a voice recording of a lady who sounded like she said Lerena Matinas and her extension was cancelled from October 3.She gave a new phone number.I rang that and just got on to voice mail.It was interesting that she said she was from Muppet Studios rather than Muppets holding company.Could muppets holding company be no more? I asked her to email me on what is happening with the Muppets and Muppets Holding Company.If I get a reply, I will let you know.
