Daniel Grogan

Editor, Certified Sleep Science Coach

Daniel is an editor at Mattress Nerd. He has always struggled to get a full eight hours (or even four hours, if we’re being honest), and has explored countless options in search of a solution to this problem. After many restless nights, he found what he was looking for in the perfect combination of white noise, weighted blankets, and tea. Daniel’s work involves editing Mattress Nerd content in order to give readers the best possible experience in their quest for a good night’s sleep. When he isn’t working on the site or making his fifth cup of Sleepytime, Daniel likes to cook and watch horror movies, but not at the same time.
