First of all, Debbie is incredible to work with. Tremendous experience, lovely personality, understands home security in a way that few people do in the entire country. She has been in this business for over thirty years. Remarkable. Then the actual installation team with Marshall Jr at the helm. They were able to get the install done rapidly in a house that presents considerable challenges. Beautiful aesthetic work and done with incredible efficiency. I cannot rate them highly enough. I strongly recommend for anyone who is looking for even a simple home security project. And they can clearly handle

Debbie was wonderful to work with. She has a great personality and is very knowledgeable about the alarm system. She walked through the house with me, letting me know what should recommended to be alarmed and why. When Marshall came to install the alarm, he was very professional and answered all my questions. He stayed to practice once the alarm was set up and made sure I was comfortable using it. They both reassured me numerous times that I can call anytime with any questions or concerns. Very nice company to work with.

Utilized Marshall Alarm to install an updated security system and security cameras at a large residence. The service started with a security consultation where a member of Marshall Alarm's team comes to the residence to understand your security concerns followed by a walk of the property to point out potential issues and mitigations. From there they build and price out several options and then set you up for installation. From start to finish their team is very professional, attentive to detail and makes sure the customer understands and can work the system before leaving. Furthermore, the central

We switched alarm companies and are delighted with the seamless transition. Very attentive staff listened to our needs, gave great advice on upgrades (at our request) without trying to oversell on stuff we don't need, and showed personal attention that other firms lack. Technicians very professional and take the time to get it right. Highly recommended.

Marshall Alarm Systems has been great to us from the first day we reached out to them. Our interaction started off with Debbie, their specialist that came to our house for the assessment. She was very friendly and very knowledgably with what needed to be done. She also looked out for our wallet as she pointed out what needed to be done but most importantly what was not needed. She had our best interest in mind. When the technician came over to install, he was very courteous and professional. He was very efficient with his time and made sure that everything was perfect. He then took his time with

We recently had a Marshall Alarm System installed at our house and the experience was top-notch. They came highly recommended by our neighbors, so no surprise that things went smoothly, but Debbie was a pleasure to deal with from the outset in terms of assessing our situation and making a recommendation for an alarm system. The install team arrived as scheduled on the day of install, and were super-professional throughout with respect to their work (workmanship & cleanliness), as well as the instructions they provided for using the system. Would definitely recommend.

Our experience with MAS has been nothing short of amazing. They are professional, courteous, and experienced in their business. Debbie provided us with a consultation of our home when we were looking for an alarm system and she was extremely knowledgeable. Those who came to our home all followed COVID procedures, wearing masks the entire time to ensure our safety as well as theirs. They took their time with us, making sure we were comfortable with the new system and answered all of our questions thoroughly. Their customer service is readily available at all times which is great. We are very happy

My primary concern was converting my system from an old nationwide provider. The team at Marshall provided the most input, concise planning, and all things considered was a good price point as well. The installation went smooth and the introduction to the system as well. As someone accustomed to using alarm systems everything else was a breeze, but the icing on the cake was knowing I have direct contact with a local representative, but hopefully I will never need that. Good to know though!
