In 1996, The Castellaws fulfilled a lifelong dream and began their own company specializing in the installation of data cabling for small to large sized businesses and other entities. They, and two technicians, began slowly building ACCESS DNSI by working on small opportunities to develop leverage in the Memphis market. They continued to grow the business by adding video surveillance and building access systems, network design, PC maintenance and wireless LANs. Through an uncommon dedication to customer service while providing quality certified installation, the Castellaws has seen their small four-person operation grow into a $14+M per year company employing over 120 technicians and staff with 70 in Memphis and 50 in Nashville.
In 2020, ACCESS DNSI added AV Systems and Integration to their products and services portfolio.
We are a certified woman owned business, and proud members of Bicsi, and AVIXA.
