“OSB Enterprises has been an integral part of our operating success with our first venture into the multi-family market in Memphis. I have dealt with Andy on a number of sophisticated projects within our building inclusive of a new energy efficient boiler, full LED upgrade to our common areas, electrical design & implementation for a new fire panel, and electrical upgrades for a modernization to our elevators. OSB has brought clarity, professionalism, and knowledge to each unique project. His responsiveness is excellent, and his resources are of the highest quality”

“Recent installation of our water pumping system. From the research prior to the proposal, the updates as to status of installation date, and the actual demo and installation of the equipment, everything went smoother than anticipated. Your staff was punctual, professional and polite. Our staff are excited, but most important our guests are getting the best water pressure ever”
