Michelle Chavez
Culinary Arts, Garden Integration, Chef

Originally from El Paso, Texas, Michelle moved to Santa Fe in 2003 and co-owns Coriander Catering.   She has cooked for former presidents and vice presidents, including George H.W. Bush, Bill Clinton, Al Gore, and Vicente Fox of Mexico.   While other schools are trying to encourage students to choose vegetables over processed junk food, Michelle and her wife and co-chef Leslie Chavez provide Monte students with good, healthy breakfast and lunch made from the freshest raw ingredients every day.
Chavez’ first love is history.  She came to food through history, especially the history of the Southwest. When she was a child in Gallup, New Mexico, her dad would load the family in the car and go bouncing down the red dirt roads exploring ancient places like Chaco Canyon, Mesa Verde, and Canyon de Shelly.   They would go artifact hunting and almost always found arrowheads or pottery shards out in the desert. When she’s not spending her time being a stepmom and conducting classes at the Santa Fe School of Cooking, Michelle also gardens and mentors young chefs.

Christopher de Jesus

Special Services and School Safety Coordinator


“Everybody is a genius.  But if you judge a fish by its ability to climb a tree, it will live its whole life believing it’s stupid.” --Albert Einstein. 
Overcoming great odds academically and socially, Christopher “DJ” De Jesus’s path to Monte has been an adventure.  Growing up in a single parent home, struggling with learning disabilities throughout his secondary education, DJ felt like that fish who was told to climb a tree.  With support from his family and pure determination, he has gone on to earn multiple degrees, most recently a Masters Degree in Education at Goddard College in Vermont.  His Master's thesis examined the past and present American educational system, his personal experiences, and explored historic and current trends that led to the current state of our education system. 

DJ has studied and traveled in Cuba, Mexico, Spain, and Puerto Rico.  He seeks to empower students to set academic and personal goals and guide them to embrace education as a way to attain their academic and life goals.
