Each one is a valued member of the team and provides the excellent customer service for which the company is renowned. All Trans Autos prides itself on its fantastic training program. Even after 25 years Tony is still attending training to keep up to speed with the fast moving technology in today’s cars. We have trained four apprentices over the period and currently have our fifth apprentice who is in his first year of training. The husband and wife team of Jill and Richard provides an excellent atmosphere. They work along side their staff, giving the garage that family feel. Their children all help within the company, inputting their skills where required, although only one of them works full time, as the company’s fleet manager.
