Owner of Mentor Lock & Safe Co. Lee MacDonald, is definitely a familar face on TV having played Grange Hill‘s ‘Zammo’, one of the show’s most popular characters ever.
Having made several appearances on TV after his successful time at Grange Hill, Lee started up his own business Mentor Lock & Safe Co., where he is also known across South London for his professionalism, reliability and expertise.
