    The Premier Provider/ADT Team did a fantastic job setting up my home security system - as someone that is not very technology oriented, they made it extremely easy for me to understand how to navigate their security platform. It was nice to find out that my 50 pound dog won’t activate the motion detectors while we are at work – only an intruder. Thank you for everything! read less

    The initial meeting went fantastic, the representative was very throughout, respectful. At installation, both Valdan and Chad were quick, respectful, mindful of COVID safety guidelines. Awesome experience!

    Chad did an amazing job setting up the system and all of the App interface with the cameras, etc. Very on top of his work and always quite personable!

    Nothing but class from the start. James Stafford and his installation crew did a great job for an amazing price.

    My wife and I purchased a home in Denver that was vacant for 2 years, apparently was the neighborhood kids party handout. In the process of remodeling the home was broken into. I like doing business locally so called Alarm Protection Group in Denver. Fernando came out that day, explained the ADT system, and it was installed the next day! He provided great service and even came out after the install to see if we needed any help and provided some good pointers. I highly recommend Alarm Protection Group and Fernand read less

    Tom is wonderful and goes out of his way to accommodate his clients' schedules! That is SO unusual these days. He came out at very specific times during the week and on the weekend to set up our alarm service for us. He wasn't pushy at all, but he listened to all of our concerns and addressed them in a very clear and knowledgeable manner. I would feel very comfortable contacting him any time I had any questions or concerns, and he encouraged us to do so. Thank you SO much Tom for your great service read less

    Finally decided to leave the alarm provider that we had been with for the past four years. Alarm Protect Group presented us tons of possibilities that were all upgrades over what we currently had. Once they were able to connect the panel cellular signal to the new monitoring headquarters (Vivint), we had our conversion wrapped up in no time read less

    I am well familiar with the reputation of ADT Security Systems and so I decided to switch from my current system. My rep was Aaron Fuller, who impressed me first with his friendliness and enthusiasm, and then later with his knowledge. It was clear he was very proud of the company and the product he was representing. I was sold before he even finished, but I was so enjoying Aaron's company I let him finish anyway! We are very excited about having a wireless system, and know we have the ADT name standing behind it. Aaron Fuller is a credit to ADT, and ADT is a credit to the industry read less

    Bill was full of information on what fix- it/maintenance projects were best to focus on. Trevor did good work in a timely manner and was a delight to have in my home. Also kept me informed of what he was doing and why. Great to find capable talent who enjoys the work! Thank you.

  • I'll Handle IT

    My wife and I have owned a rental property for many years that had been constantly rented but after the last tenant, was in desperate need of upgrades and repairs. The major problem we faced was how to coordinate the work done in San Diego when we lived in Colorado? I made a short trip to San Diego to interview numerous vendors and contractors and pick out basic designs. After interviewing numerous vendors we settled on Dave at I'll Handle It to manage the bulk of the repairs and upgrades. All I can say is Wow! What a great experience! We could not have been happier with the quality of the work, the price, and the professionalism that we found with I'll Handle it. Dave definitely named his company appropriately and stands by it. Everything went smoothly. I observed the entire process remotely from Colorado and Dave sent me pictures throughout the project. When I finally made the trip to San Diego to do the final inspection, my expectations were exceeded by the quality of the work and how well everything turned out. I was able to rent the unit to the first tenant that saw the property. It was the perfect tenant for the property, and we are very pleased with the entire experience. I don't think we could have selected a better guy to do the job. I will definitely use Dave in the future for any repairs or upgrades read less
