“I asked for the impossible on a 1 day turnaround and somehow they did it.”
Tom Neighbors
I've been in industrial hydraulic field service for 30 years. I recently stopped in to drop off an emergency test/repair. The owner took me through the entire operation, introduced me to his techs and spent over an hour with me. I wish I had met him a long time ago.
Heather Gillespie
