Khalid Abu Haddou

MEDICAL EQUIPMENT REPAIR TECHNICIAN

Khalid's inspiration for career change from restaurant management to medical equipment technician occurred while watching a television program on biomedical engineering.

Great interns make great employees, so Khalid was hired upon completion of his degree. What do I like best about my job at Network Imaging Systems? The ability to see the application of quantum physics in MRI that I studied 20 years ago in college, while pursuing a degree in Physics, Chemistry and Business.

Allen Andrews

Allen Andrews

Medical Equipment Repair Technician

Allen earned his Associate's Degree in Avionics Maintenance Technology at Trident Technical College in South Carolina. After graduating he realized that while he loved working with electronics, he had no desire to work in the airline industry. He spent some time rigging boats for a local manufacturer in South Carolina and installing Emergency Responder Radio Coverage Systems in buildings all over the state of Georgia, including the Atlanta Braves' Stadium at Truist Park.

After relocating to North Carolina, he joined the NIS team to continue building on his experience with electronics. Having worked in many different fields, he says he finds this field to be the most engaging and rewarding. Growing up, his mother worked her entire career around CT Scanners, so he understood from an early age just how important these machines are to the people who need the answers that the imaging machines provide.

His motto is "Anything worth doing is worth taking the time to do it well." In his free time, he enjoys reading, hiking, fishing, creating art, and travelling with his wife and their dogs.

Sam Galbato

Sam Galbato

Sam's fascination with electronics began in grade school where he got his hands on an electronics magazine from a teacher. Later his uncle, who was an engineer, saw the interest and aptitude in him so he further fostered his talents for engineering. He graduated from Jamestown Community College with his associate degree in electronics engineering as well as taking other Physics and Chemistry courses over the years.

After college his career began in the ultrasonics field where he traveled worldwide maintaining and participating in the R&D side. He was later a Federal Contractor fulfilling maintenance agreements to work on security detection equipment owned by the government. Sam then went into the plastics industry where he was able to work on all aspects of customer service by managing the parts sales and service operations.
Sam takes the big picture view when working: if I know how something works, I can troubleshoot and fix most anything. This work concept has served him well and created his diverse knowledge and background that customers and employers are seeking.

Best thing about this job: learning new things with sophisticated, state of the art technology that ultimately helps people and their pets.

A favorite quote of his by Henry Ford, another engineer, "whether you think you can or you think you can't, you're right." On weekends Sam enjoys spending time with family, working on projects in the workshop with his son and reading engineering articles of interest.
