We our customers

Here's what they say about us:

"Ladbrokes. That's exactly the sort of customer we want to get in front of!" Sales Manager CRM vendor
"We approached Jonathan Silverman to act as a facilitator and to provide strategic input to an Intranet development meeting held in the UK. I have worked with Jonathan previously on a number of marketing forums that required input in planning, facilitation, review of outcomes and strategic recommendations. Jonathan has an extremely broad knowledge of the world of marketing communications and it is this experience that enables him to lead discussion in such an authorative way. Jonathan also has an excellent understanding of global cultural sensitivities which was essential in planning our future global marketing strategies." Director G4S plc
"GSA provided us with a flexible and professional sales and marketing service where we could utilize one or two consultants for as many hours a month as we wanted. Your staff are highly experienced and their subtle approach very much appealed to our target audience. They got us many appointments each month. I would have no hesitation in recommending you and your team to any company serious about expanding their business." Sales & Marketing Director Payroll Services Company
