I used Carl just to feel secure while I dealt with some estate matters. He was courteous and professional. He answered his phone at 5AM and listened to my concerns and was very flexible. I used him for two days and found him to be pleasant to hang out with and very knowledgeable. He communicated in advance with the local police in case he would have to call them. I used him based on yelp reviews and found his services exactly as advertised. Would highly recommend. He has a great deal of experience in private security.
