Hosea Rosenberg, originally from Taos, New Mexico, was always good at math. After graduating 3rd in his class at Taos High School, he moved to Boulder, CO to study at the University of Colorado. His dream was to be an astronomer. During his years as a Colorado Buffalo, Hosea worked in local kitchens to pay his way through school. In, he was awarded a Bachelors of Science in Engineering Physics. After graduation, he spent some time traveling and it was then he realized he was spending more time thinking about food than about math.
Hoseas first restaurant job was as a dishwasher at the Apple Tree Restaurant in Taos. Since then he has worked his way up the ranks, from prep cook to line cook and finally to chef. Past positions include working for Wolfgang Puck, Kevin Taylor, Sean Yontz and Dave Query. His first Chef position was at Dandelion Restaurant in Boulder in 2001.
Hosea first joined the Big Red F Restaurant Group as Sous Chef at Zolo Southwestern Grill before moving to Jax Fish House Boulder in January, 2004.
