Meet Greg Mulligan

20+ Years in the Field
I am the Owner/Operator of G & D Tank Testing and Repair. G & D Tank Testing has been performing Tank Inspections since 2017. Myself, as well as all Affiliates associated with G & D Tank Testing and Repairs, are guaranteed to be CERTIFIED AND LICENCED accordingly with Transport Canada.
I personally have been conducting Tank Inspections and Testing for over 20 years. My goal is to help your company achieve a hassle-free maintenance schedule to allow you peace of mind.
I have worked over the years to have the expertise and the experience to inspect and test your equipment safely, efficiently, and to code on site — to save you money and time.
I also carry a Journeyman and Red Seal Welding ticket. With more than 20 years of manufacturing and servicing all types of oilfield related equipment, I have the knowledge to inspect your tank to every updated code — which means no issues for you and your equipment.
I look forward to hearing from your company to answer any questions you may have in regard to my services or how I can start working with you today.
