There is no mention of a "Gilian Greystone" or anyone with that LinkedIn username in the given search result. The search result is about Greystone's leadership team, but does not contain information about a Gilian Greystone or an Executive Director at Yolonuevo CO with that LinkedIn profile. Without additional information, I cannot confidently answer who this person is or provide any details about them.
