ACCESS DNSI offers unique advantages to your business because of the nature of our organization:

Independent Recommendations: Access DNSI is proud of its strong relationships with industry leaders, but we are still committed to independently and impartially recommending the best solution for individual business needs. We make our recommendations with integrity, working for you, not for the manufacturer. Reputable Providers: We procure all our systems and equipment from only the most established and reputable providers. Our mix of providers gives us the greatest flexibility in providing a tailor-made customer solution. We offer products suitable for every location, from the smallest business to networks of 10,000 users or more. All products are backed by solid manufacturer's warranties. Cost-Effective Service Contracts: In addition to the outstanding manufacturers' warranties, Access DNSI backs its services with cost-effective service contracts. Because we are sticklers for testing, we don't need to charge high service fees. We make sure solutions we install work the first time!! Design - RCDD Local Presence: Access DNSI is a Memphis-based company with a branch office in Nashville, and our biggest asset is our reputation in the communities we serve. We are proud of our community ties and recently donated an entire cabling infrastructure to the Ronald MacDonald House in Memphis. Technicians are never more than a short drive from your premises. Fully Integrated Solutions: Cabling was our foundation, but we quickly realized the value of providing comprehensive, integrated solutions for all aspects of your business's network, telecommunications, CCTV and access controls, HVAC/BAU solutions and fire system needs. Convenient Financing: If the best solution for your business requires higher-end equipment, Access DNSI can arrange convenient and competitive financing through an established name in equipment financing. WBENC & LOSB Status: As a Woman-Owned company with Locally-Owned Small Business status, Access DNSI is positioned to provide your business or organization with contracting advantages. Outstanding Service: Service is Access DNSI. We provide small-company customized service with large company results. Basically, if you're not satisfied, we're not satisfied. Testimonials from our customers show that outstanding service is the best value we provide.

We Specialize in the Unexpected

At Access DNSI, we practice customer service by meeting tough challenges. Ask the manager of a Memphis Best Buy store, where a major cable installed by another vendor was compromised by water leakage, shutting down the store's entire network. Access DNSI completely reinstalled the network backbone and had the store operational again in a single day. Or when the July 2003 Memphis windstorm left hundreds of thousands of customers without power. That weekend, we were tasked to replace an existing network for the Exchange Club of Memphis. The system included VPN, remote control, and portable user access capabilities. Work began on Friday evening and when the Exchange Club staff arrived Monday morning, the network functioned perfectly, without error or interruption. Or ask the law firm where an employee clerical error deleted all records of 80% of the firm's past and present cases, with no backup. For Access DNSI, it was a challenge not a problem as we completely restored all the firm's “lost” records in one night. Whether your need is to upgrade or expand an existing cabling infrastructure, a new phone system, video surveillance

I can recommend John Catellaw and ACCESS DNSI without reservation. They have been a key contributor to our success in installing a citywide LAN/WAN ATM infrastructure for the Memphis City Schools. This installation has allowed Memphis City Schools to implement one of the most current technological networks with Voice, Video and Data Capability.
