Joshua Pollack, a self-professed "Jersey boy" from Bergen County, came to Colorado in 2002 to attend the University of Colorado Boulder. He liked the state, but missed the bagels from back home. He was convinced that Colorado-made bagels could be more than just bready rings, though, and after other entrepreneurial endeavors, he decided to go to culinary school while taking post-graduate business classes. He also spent time in New York City learning the bagel trade and testing the water there before tinkering with Colorado’s to replicate the mineral content of the Big Apple’s H20. The resulting bagels proved exquisite and addictive, with a tender crumb and a delicate skin providing equal parts crackle and chew. In 2014, after a short stint selling them at the Galvanize co-working space in the Golden Triangle, Pollack opened Rosenberg’s Bagels & Deli in a long-vacant building at 725 East 26th Avenue in Five Points.
