Actually, its just historical coincidence! In February 2009, when Bill Meyer was considering names for his company, he found the domain name PremierHotTubs.com was owned by a "squatter" (a company who buys domain names simply to resell them). Driving past Premiere Insurance on I35 one day, Bill had an idea! He researched PremiereHotTubs.com and discovered it was available so, he bought it and the rest...as they say...is history!
However, about a year later Bill discovered the company that had owned PremierHotTubs.com had not re-registered the name, so he purchased this domain too! But, by that time Premiere Hot Tubs was already well established and Bill decided not to change a good thing!
