“I wanted to reach out to you to let you know how extremely impressed I was dealing with your team! Your company has been servicing our fire extinguishers for years…Everything worked out, but I would not have been able to get things resolved quickly without your great team. Truly appreciative of everyone's willingness to roll up their sleeves and help!” Commercial Property Owner "I’m very happy with Kistler O’Brien's service primarily because anything I ask for is never a problem. Every time I need something, I get exactly what I ask for. I trust that while KOB is here, I don’t have to follow them around or make sure that they work with our Loss prevention/monitor team. They know the numbers to call and always leave the system in good condition.” Grocery Chain Leader “Great, dependable company. On-time for appointments and very thorough with the inspection. Inspectors are courteous and knowledgeable and pay attention to detail.” Business Owner “Kistler O'Brien is my go-to for fire suppression installation. They handle their projects smoothly and with a lot of care. I have been working with [them] for a few years now and they have always gone above and beyond to make sure my projects stay on track and turn out great. I highly recommend them for any fire protection needs you may have. Can't wait to work with them again!” Paint Booth Manufacturer “Best service, best techs, best prices. Couldn't possibly recommend them more highly. They earn every star, year after year.” Local Business Leader “The gentlemen in the office are absolutely amazing! This is the second time I had to walk in for a business-related issue. They are so willing to help even on the day I came in right before close! They are very welcoming and extremely knowledgeable! Thanks for the help!” Small Business Owner Don’t just take our word for it Testimonials
