About Mark Schark

I’m not the favored son, but trusted and respected. I’m tenacious and display leadership and confidence. My salesmanship is somewhere between carnival barker and used car salesman. In negotiations I’m the pit-bull. When our backs are against the wall, I’m on the field somewhere for the “Hail Mary” play. My immediate supervisor manages me, not my process. My sweat help build this organization. If you cut me I bleed company colors.

Listed skills include Desktop Deployment, Service Desk Management, Laser Printers, Thermal Printers, and 9 others.
