About Waterpik Since 1962, Water Pik, Inc. has been a leader in developing innovative shower heads, sinus rinse, and oral healthcare products with over 500 patents and award-winning designs. The company that became Water Pik, Inc. was founded in Fort Collins, Colorado by hydraulic engineer John Mattingly and dentist Gerald Moyer. These two trailblazers created an oral irrigation device that did not leak; in fact, it was so effective that today's Waterpik Water Flosser is based upon the same exact principle and design. Of course, after achieving perfection with their first product, Water Pik grew more bold and introduced the first massaging shower head, which drew upon the pulsating spray of the oral irrigator and became a tremendous success. With a must-have dentistry tool and a sought-after luxury item under their belt, Water Pik, Inc. had the freedom to push boundaries and create hundreds of other new products and patents over the decades and, as they say, the rest is history!
