Here at TDS we take great pride in our team. We know that trust is important and we want you to know our team like your own. We are introducing our monthly "Meet the TDS Team" feature.  Safety is our #1 priority at TDS and so we are introducing our new National Safety Manager first.  Meet Mr. Patrick Gardner!

1.     Tell us a little bit about yourself. 

I have been an Environmental Health & Safety professional for over 23 years. I have worked in several different industries such as: Electrical Contracting, Oil/Gas and Pipeline, Midstream, and Rail Car manufacturing. I received my Certified Safety and Health Official (CSHO) certification in both General Industry and Construction. My wife and myself have 6 children between the two of us. 

2.     What do you like to do for fun? 

My hobbies are playing golf and fishing whenever possible. 

3.     Tell us something interesting about yourself that people might not know. 

I played baseball at Blinn College and was drafted to the Atlanta Braves organization with their Double A ball team, which at that time was the Greenville Braves. 

4.     What’s your best safety tip? 

Ask yourself why it’s important to leave work the same way you came in today? Is it because your children could be affected by my poor decision that day or will my wife have to be both mommy and daddy? The answer is simply YES.
