- AKAnthony KellyMay 6, 20265.0I had a great experience at Tri Supply thanks to Steve and Sean. Both of them were extremely helpful, knowledgeable, and professional throughout the whole process. They took the time to answer all my questions, made everything easy, and provided excellent customer service from start to finish. It’s hard to find sales associates who genuinely care about helping customers, and these two definitely do. I highly recommend Tri Supply and appreciate all the help from Steve and Sean!
