A Note from Our Founder

I started Martel 1984 to give businesses on Delmarva a dependable choice for their business telecommunications needs. Now in our 38th year, we still operate on the same values of integrity and innovation. We remain resilient to stay on the cutting edge of technology, with cloud based VOIP solutions that rival any of our “national” competitors. What they cannot rival is our customer service, which we still handle the old-fashioned way: live, personalized to your needs, and focused on solving problems and making it work for you – just how it should be.

We’ve used Martel for years to do our structured cabling and phone system. I’ve worked closely with Shawn countless times. He’s very knowledge, professional, nice, and a great guy to work with. Highly recommended.

[The Martel] team was professional and never interrupted a single sale.

Mark and his team did a fantastic job for us! Mark took the time to go through our needs including planning for the future. Having gone through two new point of sale systems since we’re sure glad he did! Martel completely cabled our building along with installing a new phone system. The weatherized cordless phones have been invaluable through the pandemic. His team was professional and never interrupted a single sale. Thank you Martel!

Would recommend them to anyone seeking out assistance with their communication needs.

Mark and his team have been attending to the needs of my funeral homes going back over almost 30 years. As we have grown to multiple locations his company has always been there to help us upgrade in order to serve our clients professionally. Whenever we need service or have questions they have always been responsive in a very timely manner. I give them five stars and would recommend them to anyone seeking out assistance with their communication needs. Yes there are the big guys out there but we would rather deal with a local firm that we actually can talk to rather than sit for 3 hours in a phone que. Besides, the big guys do not reinvest in our local communities. Our very best for continued success. Sincerely, S. Keith Parsell CEO/President- Parsell Funeral Homes & Crematorium

Five stars are a mere formality for the symphony of security they conducted. Martel Inc. is the perfect partner for any business seeking an exceptional security solution.

As a wedding venue owner, ensuring a safe and secure environment for our clients is paramount. Martel Inc. elevated that commitment to an art form. Ken Trojan, the consummate sales professional, meticulously assessed our needs and presented a security solution that resonated with our vision. His deep knowledge and clear communication ensured we were fully informed at every step.

Then came Tony, the technician, whose skillful installation transcended mere functionality. He approached the venue with the meticulousness of a security architect, strategically placing cameras and sensors to create an invisible, yet impenetrable shield. His expertise instilled a level of confidence that is invaluable in our industry.

Martel Inc. didn’t just install a security system; they instilled peace of mind. They allowed us to focus on creating unforgettable memories for our clients, secure in the knowledge that their most cherished moments were safeguarded. Their work wasn’t simply a service; it was a partnership built on trust and expertise.

Five stars are a mere formality for the symphony of security they conducted. Martel Inc. is the perfect partner for any business seeking an exceptional security solution.
