Adverts were put out and a young man, amongst many, called Adam Tanner came into the picture and was given an opportunity to work for one day with Alex and the rest now is history. An apprenticeship for Adam, good grades at college, a mind for retaining technical knowledge and systems, got matched together with Alex a skilled practitioner with years of knowledge and experience the team was born.
