“ I was introduced to King Flex and Joey through my previous employer. Joey has been amazing to ensure that all our demands are met on time. When there are supply-chain issues, Joey ensured that I knew what the stock status was. If there was anything I would need in the meantime, he would even get that freighted interstate to make sure I’m not left stranded for materials. Always prompt to respond or callback.
Amazing service! Exceptional support! “
