Dan Almendarez, Manufacturing resident CWI & welding supervisor at Team Furmanite

Dynamic Laboratories is my ‘go-to’ testing laboratory. If I call them at 5p.m. and need a weld procedure overnight, they do not hesitate.

They did a great job, and I was able to deliver for my customers. Dynamic Laboratories didn’t disappoint me at all. They are really polite and professional.
