Industries We Serve

DHI Technical Services works with a wide range of businesses and organizations across New Hampshire. We understand that different industries have different technology requirements — the network a dental office needs looks nothing like the one a towing dispatch operation runs on. We bring hands-on experience across the sectors below, so you get solutions that fit how your organization actually works rather than a generic one-size-fits-all approach.

Medical & Dental Offices

Healthcare practices depend on reliable, secure connectivity to run practice management software, electronic health records, and medical devices — often all at once. We design and maintain networks with HIPAA considerations in mind, including VLAN segmentation to isolate clinical systems from general office traffic, secure remote access for providers, and VoIP phone systems that keep your front desk running smoothly. We also provide managed IT support to keep your systems available when patients are counting on you.

Attorneys & Law Practices

Law firms handle confidential client information every day, which means your network and communications infrastructure need to be built with security and reliability as the foundation. We set up isolated networks for client-facing and internal systems, deploy VoIP phone systems with proper call handling and voicemail, and configure offsite backup so your case files are protected against loss. Whether you are a solo practitioner or a multi-attorney office, we tailor the solution to your firm's size and workflow.

Automotive & Towing

Auto repair shops and towing operations need technology that works as hard as they do. We handle shop management software networking, rugged WiFi coverage for shop floors and service bays, and VoIP or analog phone systems for your front counter. For towing fleets, we program Motorola portable and mobile radios with the frequencies, tones, and channel layouts your dispatch operation requires. We also provide ongoing radio maintenance and programming updates as your fleet or coverage area grows.

Oil & Natural Gas

Field operations in the oil and gas industry often take place far from reliable infrastructure, which makes robust communications critical for safety and coordination. We program and service Motorola portable and mobile radios for field crews, set up remote site network connectivity for monitoring and reporting systems, and provide rugged networking solutions built to perform in demanding environments. When your crew is working remotely, communication failures are not an option.

Co-ops & Food Stores

Grocery co-ops and food retail operations rely on point-of-sale systems, inventory management, and back-office connectivity running in unison throughout the business day. We design and install the structured cabling, managed switching, and wireless infrastructure your POS systems depend on. Guest WiFi networks are deployed on a separate VLAN to keep customer traffic isolated from your payment systems — an important step for PCI compliance. For multi-location operations, we can extend consistent networking across all your sites.

Towns, Libraries & Schools

Public-sector organizations face unique challenges: tight budgets, aging infrastructure, and the need to serve the public reliably. We work with municipalities, public libraries, and K–12 schools to deploy managed networking, public WiFi, inter-building fiber connections, and VoIP phone systems for municipal offices and administrative staff. We understand that public institutions need straightforward solutions without enterprise-level overhead, and we price and scope our work accordingly.

Law Enforcement

Police departments and other law enforcement agencies operate networks that demand strict security and reliable uptime. We provide VLAN-segmented network design to keep dispatch, body camera evidence storage, and administrative systems appropriately separated. We program and service Motorola portable and mobile radios for patrol and command staff, and configure secure remote access for investigators and administrators working in the field. Our goal is to make sure your technology keeps pace with the demands of your department without creating unnecessary complexity for your staff.
