"May I take this opportunity to say how very pleased and impressed I am with your firm’s efficiency and professionalism, as well as your flexibility. I have been using a variety of different firms for DNA and drug and alcohol testing for years as solicitor for the local authority, before I found you, none others have the approach with all the staff members that I was seeking, or the speed at which you respond to queries, issues etc.. before I came across Cellmark. Thank you."
