Here's what they say about us:

"Just wanted to say thanks to Jonathan and the team for all of their efforts to put us infront of the people we need to do business with. Lead generation is always a challenge and GSA enabled us to increase the number of leads into our business. I was very pleased with the professional service and results and Carol is brilliant. I look forward to working with you again in the future" Sale Director DCS (London) Limited
"I thought our telemarketer was absolutely brilliant. I also thought the attention to detail was great, the focus on me (the client) was good and the reporting was excellent." Manager Law Cost Specialists
"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
