Our Story
TREYSTA Technology Management has proudly served businesses throughout Central Pennsylvania and Northern Maryland since 1995. What began as a local IT support company has grown into a trusted Managed Service Provider, helping organizations of all sizes simplify technology and achieve their business goals through proactive IT management.
In 2014, partners Henry Grossman and Steve Quinley brought together two established companies—ComputerWorks and Net-Aid—to form what is now TREYSTA Technology Management. At the same time, the company made the strategic decision to transition from the traditional break/fix model to a proactive Managed IT Services approach. Rather than waiting for technology issues to occur, TREYSTA continuously monitors and manages clients’ networks, systems, and devices to minimize downtime, improve security, and maximize the value of every technology investment.
As technology has evolved, so has TREYSTA. Today, our experienced team provides comprehensive IT support in Central Pennsylvania, including Managed IT Services, Cybersecurity, Microsoft 365, Cloud Solutions, VoIP Phone Systems, Business Continuity, Security Awareness Training, IT Project Management, and Strategic Technology Consulting. Whether supporting day-to-day technology needs or helping organizations plan for the future, our focus remains on delivering reliable solutions backed by exceptional local service.
In 2019, John George was promoted to President after serving as Vice President of Sales and Marketing. With more than 20 years of experience in the IT industry, John continues to lead TREYSTA‘s strategic growth while fostering a culture centered on innovation, accountability, and outstanding customer service.
Today, TREYSTA proudly supports businesses, municipalities, nonprofit organizations, educational institutions, and professional organizations throughout Central Pennsylvania and Northern Maryland. Our commitment to technical excellence and customer satisfaction has earned national recognition, including multiple appearances on the prestigious Channel Futures MSP 501, recognizing the world’s top Managed Service Providers.
While technology continues to change, one thing has remained constant—our dedication to helping businesses use technology as a competitive advantage. We build lasting partnerships through responsive support, proactive technology management, and a commitment to doing what’s right for every client.
