Secondly the reason why I chose Cellmark out of 4-5 DNA companies from the list given was due to the fact that Cellmark responded to all my inquiries efficiently, professionally and promptly. Other companies were quite poor in that so I decided to go ahead with Cellmark."

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."
