ANGELO MARTINEZ
Tech Support
“You may not end up where you thought you were going, but you will always end up where you were meant to be.”
Angelo’s career path has a long straight line, with one very hard turn. Prior to joining AAMSCO as a Service Technician, he was our company president’s barber for 20 years. Once the pandemic hit in early 2020, Angelo decided to make a career change. When Geoff Riordan learned this, he knew he had to try to bring him on board.
“I knew that Angelo had great communication and organization skills. Over the years he also told me about servicing his own cars by reading manuals and that he also had interest in various software applications,” Riordan said.
Since joining AAMSCO in March of ’21, Angelo has excelled in understanding identification systems technology. Compliments about Angelo from customers and coworkers are common.
DREW LEDBETTER
Tech Support
Drew worked for AAMSCO as a low-voltage/security subcontractor for a year before he was hired as a technician. Drew worked at a security company years ago. He holds an electrician's journeymen’s license and sergeant's stripes, having served in the U.S. Army for 4 years.
According to Geoff Riordan, President, “We were thrilled to bring Drew on board. His level of experience in the security industry has been a tremendous benefit to our Service Department. He has also demonstrated that the challenges of learning new technologies associated with the ID industry don’t faze him.”
BEN FINDER
Tech Support
Ben Finder is the latest Service Technician to join AAMSCO. Ben recently completed his CompTIA A+ certified IT certification in order to begin a career in Information Technology. He has demonstrated an eagerness and willingness to get things done. We believe he will be a great asset to the service department based on his knowledge of PCs and networking.
RALPH MALONE
Tech Support
Ralph is one of our newest staff additions, yet he's by no means a rookie with regard to AAMSCO. In fact, he was a long-time customer of the company prior to him joining the service team. With a background in education, network engineering, video security sales not to forget biology, chemistry and physics, Ralph knows how to MacGiver his way through just about any technical challenge that may come up for customers.
His resume backs that up:
Bachelor of Science, Biology, Chemistry, Physics - Henderson State University. Master of Science Education, Arkansas Tech University, Founding member of the Office of Distance Education at Arkansas School for Mathematics, Sciences, and the Arts (ASMSA). ASMA is where Ralph was prior to joining AAMSCO, and in his 23 years there he was a network engineer, system administrator and a trouble shooting pro on countless occasions.
So when you take all of that into consideration, his comment about AAMSCO's service is well taken:
"Having been a long-time customer and now an AAMSCO employee I can say from both sides of the aisle this group's commitment to customer service and product knowledge is second to none."
ROB MCDONALD
Tech Support
Rob McDonald brings more than two decades of hands-on electrical experience to AAMSCO. He has been an electrician for 21 years, including 16 years as a journeyman, building a strong foundation of technical expertise and problem-solving skills.
Rob and AAMSCO’s Service Manager, Drew, first worked together during their early careers at an electrical contracting firm. Five years later, Drew recruited Rob to join the AAMSCO team—a reunion that came at exactly the right time. After undergoing a hip transplant, Rob began reflecting on the next chapter of his career, and the opportunity to expand into a new side of the industry with AAMSCO was a perfect fit.
Married with three young children Rob values family life. His wife works from home, and outside of work, Rob enjoys staying active through outdoor activities such as kayaking and hiking.
