QUEENSLAND – Brisbane North Drug Testing

Terry Gusterson – General Manager

Having spent 10 years as a Police Officer in Queensland and then 7 years  as a Safety Officer/Trainer Assessor in the Mining Industry, I’ve seen and experienced firsthand the devastating effects of Illicit drugs in the workforce as well as in the greater community.
When I researched TDDA and how they are trying to “Create a Drug Free Environments”, I knew that I wanted to be a part of that process.
The opportunity to help people and  to offer a Safe Working Environment was too good to refuse and I joined TDDA over 4 years ago. I still feel very passionate about what I do and enjoy the process of helping people and their family. Knowing that the person working side by side with you and me is not effected by any illicit Drugs or Alcohol is a positive thing that I enjoy being a big part of.
I enjoy public speaking and often present to community groups as believe education is a key factor in addressing drug and alcohol risks.

Yoshiko Gusterson – Operations Manager

I first heard about TDDA through a family member who had been drug tested by a TDDA franchisee. He advised me that TDDA were extremely professional and thorough. After researching the company through their website we learnt that TDDA’s vision was to “create a drug free environment”, that statement really hit home to me as I would love nothing better than to raise my family in a safe drug free environment. I believe this is possible one step at a time and I am passionate to be on that journey with TDDA.
