Onsite IT Support

Onsite IT Support Services

Expertise at your door.

Reliable and efficient IT support in Dallas, TX and surrounding areas is a necessity for any sized business. The costs of IT related downtime and security breaches are often underestimated. Not only do they cost in time and productivity, but they can also negatively impact your company’s reputation.

Managed IT is growing in the Dallas IT support industry. Small and medium-sized companies require specialized IT solutions but might not have the budget or the interest in hiring their own team. Those days of having one person on staff who is handy with computers are gone. The importance of data security, cloud accessibility, and network connectivity should be taken seriously by any sized company. Managed IT allows any company access to an entire IT department when needed, without having to hire an entire department in-house. 

3T Pro is a Dallas IT support and consulting firm that has been serving the wider Dallas area since 1992. We specialize in IT support for small and medium sized businesses. Countless companies in a variety of industries rely on 3T Pro to manage their IT needs. Some of our clients include companies in law, medicine, oil and gas, architecture, interior design, financial services, accounting, manufacturing, food services and business consultation.
