"We worked with GSA over two campaigns for more than a year and they provided us with high-quality telemarketing services. This has allowed us to keep a consistent flow of sales leads into blue-chip organisations from which we have generated new business. I would recommend GSA to any company looking to develop new business" Chief Executive

"On 1st July 2015 the SMI Group sales team enjoyed an inspirational training day with tele-marketing trainer Jonathan Silverman. The course was well planned and all the team have admitted to learning something valuable. I would certainly recommend the course to anyone who wants to grow in their knowledge of tele-marketing techniques." Sales Director
SMI Group
"As a relatively new venture, Blue Bamboo Consulting called on Jonathan's expertise to help us create a viable marketing strategy. During our meeting it became apparent that Jonathan's input was far more valuable than ably fulfilling this specific brief. GSA was able to help us understand the technical options available (within the marketing piece), educating us as to the best routes to market with our burgeoning proposition; furthermore, we ended up with a template business development plan whereby all Jonathan's insight into sales and marketing could be applied and, importantly, aligned to our particular vision. GSA went the extra mile to help us get what we wanted, sensitively and professionally challenging our expectations & goals. Excellent work - thank you!" Director
