Dan Hill

Southwest Oral Surgery

I have relied on the Joseph Company for their continued support and service for all of our IT needs. As you can imagine, being in the healthcare field can be very demanding, and it is imperative that our systems are current and running flawlessly so that we can take care of our patients. The Joseph Company has always been prompt, thorough, and reasonable. They have always treated us like we were family.

Placard Wizard

Our company provides software as a service to some of the largest transportation companies nationwide. For over 16 years TJCO has been our trusted go-to software developer. TJCO support and response times go over and above expectations. We appreciate their professional approach and look forward to working with them again on our next development project.

Emily Castle

Castle Design

We rely heavily on their expertise when it comes to keeping our 17 networked computers and a multi-line phone system in good working order….all installed by TJCO. The staff provides a high level of service, and they are always just an e-mail or phone call away when we need assistance. We always appreciate their quick response time and their excellent working knowledge of our system.

Susan Goldenberg

Ingenium Partners

I have worked with The Joseph Company for 15 years. As a small business, we have relied on them for all of our technology needs. Even a small business has “big” issues, and TJCO has been an excellent partner. Aside from their expertise in technology, their commitment to customer service has been outstanding. I would highly recommend TJCO.

Dr. Fiscella

Wilmington Clinic

TJC first consulted with me to establish the clinic's first online storefront. For over a decade we have trusted the technical expertise of TJC to guide us through the dos and don’ts of the web. They are willing to answer any technical questions and they make it easy for a nontechnical person to understand. Their customer service experience is outstanding and we’ll continue to work with TJC.

We help businesses modernize legacy systems, consolidate applications, and implement scalable technology solutions that lower operating costs while maximizing long-term return on investment.

Technology should simplify your business—not complicate it. From custom web applications to IT infrastructure and cloud solutions, we create systems that improve communication, increase productivity, and give your team the tools they need to work faster and more efficiently.
