Leadership

Our leadership →

TDDA are fantastic, the team there are very helpful when you are getting started and trying to implement new Drug and Alcohol polices, they helped us and I don’t know where we would be today without their help.

Their service is second to none: they make the staff feel comfortable when completing the drug testing they are very informative to all staff and management but at the same time the testing is very confidential. They have the ability to drug test on site, off site and any time of the day which makes it so easy for us. What a fantastic team!!!!!
