After initial emails and a call with Carlos, we set up a meeting to review our needs at our house. Throughout the entire process, Carlos was prompt in replying and always very helpful and gave us great customer service. When his team arrived to complete the install, the work was also completed professionally. The team of three wore masks and shoe covers when inside the house. They were very courteous and explained everything they were doing prior to doing the work. I was really impressed by the job from start to finish. I'd recommend Carlos and Security Doctors.

Two other companies wanted to rip all of it out and start over. He got the existing sensors talking to his own hub without pulling a single wire, swapped the panel, and the whole thing was live before dinner.

I called to request a locksmith to unlock my friend's apartment because my luggage was inside, and…read moreI had a train to catch in about two hours. None of his roommates were home, awake, or answering their phones, so I was starting to panic a little. From the start, the staff were incredibly patient and kind. They gave me a reasonable quote right away and said they could have a technician there within an hour. The technician called me as soon as he was on his way, and his ETA was only 15 minutes! In the meantime, we found out that one of the roommates could come let us in. I called back to cancel, fully expecting to still pay a $89 service fee since the technician was already on his way and almost there. To my surprise, they told me not to worry about it and canceled everything at no charge! The entire experience was so easy, and every interaction was quick, friendly, and professional. Even though I ended up not needing their services, I was genuinely impressed by their kindness and customer service. Truly night and day compared to other locksmiths I've dealt with in the past. I would absolutely recommend them and will definitely be calling them again if I ever need a locksmith!

Great experience and would do business again!

About 2 weeks ago I signed up for conceal & carry classes with Glenbard Security. I was…read moreapprehensive as I'm not a regular client at shooting ranges but was considering becoming one, and I wanted to know more about the carry/conceal aspects of owning a firearm in Illinois. The classes are priced competitively, take 16 hours which included qualifying time at a local range, and had ten people attending. Much of the classroom material consists of the Illinois State Police worded laws and restrictions, but the instructor Jason took the time to explain anything that wasn't clear. Being in law enforcement, Jason also shared plenty of practical experience and videos of real-life situations. If you are considering a conceal & carry class I recommend Glenbard Security.
