A bit about The Jelly Babies Charity

About 75% of Jelly Babies fundraising is for the Lullaby Trust and in particular for their Care of Next Infant Scheme (known as CONI) by providing funds for breathing monitors. In addition, we have also supported the helpline and provided funds for information leaflets that is given out to parents.

The remaining 25% of our fundraising is to purchase essential pieces of equipment for the children’s Wards of hospitals and the last donation was to the Starfish Ward at Watford General Hospital.

We are looking forward to repeating the exercise." General Manager Automotive data supplier
"The preparation that GSA put into our campaign was highly professional and set the foundations for an ongoing successful campaign. The initial meeting with Jonathan was so valuable in transferring information and assisting to embed GSA into our business. The questions he asked challenged my thinking about the offer we provide and how we differentiate ourselves. This is obviously crucial in converting prospects to Customers ..... once you have been able to secure a meeting with them of course ! Tyna has been absolutely marvellous in selling our initial offer to secure these meetings for me; with the right people. As far as our prospects are concerned Tyna is their first contact with our business. The quality of the information, all sent in a timely way; followed by weekly reports re iterates the professional company that GSA are. As a result of the appointments that Tyna has set I have then been able to convert prospects to sales. We have already extended the contract to continue the success of working with GSA ."
