Marcos Sierra, is a native New Yorker who was born at St. Lukes Hospital in Spanish Harlem to parents of Puerto Rican descent.  His father migrated to New York where he met Marcos’ mother, who was born in Brooklyn, New York.  Sierra was raised in the Bronx by his single mother before she moved the family to the Douglass Houses, a NYC Housing Authority (NYCHA) public-housing development on Manhattan’s Upper West Side.  It was growing up in NYCHA where Marcos learned firsthand the substandard living conditions that many of New York’s most vulnerable residents are forced to endure.   

Marcos attended PS 163 on Amsterdam Avenue in Manhattan, where he was introduced to the Gifted & Talented program of the New York City public school system. During his senior year at Manhattan’s Joan of Arc JHS, Marcos’ mother moved the family back to Fordham Road and Davidson Avenue in the Bronx where he finished his middle school education at IS 115 in the borough’s Fordham section.  

After Junior High School Marcos attended both Walton and Evander Childs High Schools before receiving his GED in 1999. Marcos continued his education by attending Technical Career Institute where he received his Associates in Business, Management, and Accounting, and Bronx Community College, where he began his undergraduate degree in Psychology.  

A resident of Norwood for over a decade, Sierra lives with his partner Irina and their blended family that includes 4 amazing children, daughters, Brianah, Abygale, Leah, and their son Maxwell Emerson.  

Sierra began his political career in 2011, joining the campaign of then insurgent, small businessman, Mark Gjonaj, who ran successfully for the seat of Member of the Bronx’ 80th New York State Assembly District.  In 2013, Sierra was appointed to the position of Male District Leader for the 80th Assembly. In this role Sierra served as a bridge between the community and area’s elected officials.  This experience gave Marcos a new found appreciation for the political process.  It was at that point, Sierra knew public service was the path he wanted to pursue.  From job fairs, to community events, to working with elected officials and community stakeholders, to playing a significant role in addressing the devastation that the illegal and deadly drug K2 imposed on our communities, Marcos has consistently demonstrated his genuine desire and effort to improve the quality of life of his neighbors.

After stepping down from his role as Male District Leader in 2018 to care for his mother who was diagnosed with cancer, Sierra decided in 2020 to run again for the position of District Leader.  With 70% of support from the voters of the 80th Assembly District, Sierra was overwhelmingly elected to again serve as a bridge for the people. A position in which he humbly takes pride and reverence.

Sierra is a “doer”.  He used his AAS in Business Management to become an entrepreneur starting his own business, El Flanadero.  He is the former Chair of Youth, Education, and Libraries for Bronx Community Board 7 (CB7), and is currently a member in good standing of the Louella Hatch Democratic Club.

With his strong understanding of the workings of the political process at all levels of government, his life experience that has directly taught him the difference between inequity and inequality of community resources, Sierra looks forward to providing fair and equitable representation to all of the neighborhoods that make up the quilt-of-diversity, that is the 11th Council District of our great borough of the Bronx!
