Chef Jenna

Executive Pastry Chef Instructor

Jenna Dilullo

Growing up in a big Italian family from Fishkill, New York, food was the focal point of every get together. Chef Jenna learned from a young age just how important, and celebratory, food can be. Her love for pastries and the culinary arts started at those family meals and continued to grow with time. Chef Jenna started her culinary journey in a small bakery at the age of 15 washing dishes and baking cookies for the lunch rush. She then went to The Culinary Institute of America in Hyde Park, NY, and obtained an Associate in Occupational Studies (AOS) where she learned the ins and outs of specialty breads, chocolates and confections, and menu development. From then on, Chef Jenna has worked in high production bakeries and as the Assistant Director of a flavor company where teaching the science and components of a flavor to future clients became her passion. After obtaining her Career and Technical Education (CTE) certificate, she moved to Denver, Colorado where she worked at Mercantile as the Assistant Pastry Chef, and Etalia as a Gluten-free bread baker. It was here that she began honing her craft and learning the science of every dessert and bread she could get her hands on. This journey led Chef Jenna to Cook Street where her passion for pastries and love for explaining the what, why and how, come together as one.

Chef Instructor

Senna Cetera


Chef Instructor

Sam Friedman

After earning a Master’s in Teaching from the Colorado College, Chef Sam decided to break from a direct teaching path and pursue his passion in cooking by attending Cook Street’s Professional Culinary Arts Program. Throughout his educational pursuits in K-12 teaching and working in schools to promote the development of social and emotional literacies in students, his love, connection, and devoted preparation of food remained. Interacting with and sharing food represents the most prolific thread of Sam’s interests and passions. In his work as an instructor at Cook Street, Sam strives to continue to connect with others through the communal and interactive learning opportunities present in this uniquely educational and culinary setting.
