Our Story and Company History

Tyrosys was born out of our company founder and CEO, Bill Chapman, passion for technology in October 2002.

Frequently customers ask us about the origin of our company name. Tyrosys is more than just a name, its a commitment towards our customers and a motto for how we do business.

Tyrosys was created with the focus that technology is always evolving so we must continually learn in order to be experts, and that buying decisions are made with the systems and passion dedicated to provide quality service.

We are humble and understand that people have many choices when it comes to the service of their Mac Computers and Fiber Optic Test Equipment. Our technicians are focused on providing clients with quality repairs, knowledgable solutions, and quick turnaround.

Tyrosys' History — Serving for 17 Years

Tyrosys started on October 1, 2002, in Plano, Texas with the original focus on service and repair of electronic and fiber optic test equipment, and quickly following the sale of quality value priced oscilloscope probes.

Our original two brands, TyroLab and ezProbe have grown into mature brands that are known for quality with over a dozen years of proven success.

In April 2004 Tyrosys became a C-class corporation in order to focus on our broader corporate growth and commitment to our founding standards.

In spring 2007 Tyrosys earned an Apple Authorized Service Provider partnership with Apple. Meeting, and maintaining, Apple’s strict requirements of Certifications and accreditation, Tyrosys is focused on providing Mac owners Authorized service and repair of their computers.

The summer of 2010 was a milestone for Tyrosys by opening our first branch location in Georgetown, Texas. Focused with serving Central Texans, by locating in Georgetown we are able to service regional clients both from the greater Austin metro as well as Waco and Killeen / Ft. Hood.


In October of 2018 Tyrosys relocated our headquarters office to a new freestanding location on the north side of Bonham, Texas. This new location features much better accessiblity including our own parking lot and will enable even better our productivity for the start of our 17th year.

The Tyrosys Management Team

Bill Chapman, our President and CEO


US Air Force trained and skilled, I moved from technician to sales manager in my early years before moving on to help build a couple more technical rental companies.


2002 offered the right climate to begin building a new industry player.

Territory by Technology ®, coupled with a humbleness in the face of new opportunity, is the foundation of our phenomenal success and our hallmark for steady growth.

Grant Chapman, our COO and Operations Manager

Bill Chapman, President and CEO of Tyrosys Corp


I love technology and have centered my career around it.

From my early days as a kid fixing Apple ][e computers, to growing up through the rise of the internet in the 90's, I've always had a knack for fixing computers, tinkering with electronics, and a passion for teaching the technology to others.

I started out my career working for Apple, which re-ignited my passion for Apple products. Since then I've taken it upon myself to become a master of Apple technologies through official certifications and Apple accreditations.

While growing my skill set, I've earned my stripes and have helped build a company that I am very proud of. Our goal is to remind clients of what true customer service is; quality, craftsmanship, and Texas hospitality.

I look forward to the opportunity to serve!
