Siree I. Morris has established himself as a pioneering force in real estate development and community impact. Through designing and constructing large-scale projects, he recognized the critical importance of market sustainability via sound property management and construction practices. This insight led to the founding of MCI in 2013, a vertically integrated firm that develops and manages its own properties
throughout Northern New Jersey.

MCI has been at the forefront of innovation in the real estate industry. Notably, in 2015, Siree designed and received approval for New Jersey's first multi-family housing project constructed from shipping containers, a groundbreaking initiative that garnered attention from The Wall Street Journal. Initially specializing in urban infill multi-family developments,

Siree’s projects consistently reflect his ability to identify opportunities that drive economic growth. MCI has since expanded its portfolio to include transformative low-, mid-, and high-rise projects. Among its flagship developments, MCI broke ground in September 2024 on a $336 million mixed-use project in collaboration with the New Jersey Performing Arts Center (NJPAC). This development includes a 25-story tower and a six-story low-rise building.

Most recently, the firm began construction on a $94 million, 250-unit mixed-use project with the Newark Museum, featuring a 12-story mid-rise and a seven-story low-rise structure housing an art gallery. As of January 2025, MCI has 600 units under construction, 71 units slated to break ground in Q3 2025, and 421 additional units scheduled between 2026 and 2027. With its robust pipeline, MCI has solidified its position as a leader in commercial real estate.

Siree, MCI, and their ventures have been widely recognized, with features on NBC, ABC’s Good Morning America, MSNBC, CNBC, WPIX 11, News 12 NJ, The New York Times, and the Commercial Observer, among others. He was named a top influencer of color by ROI-NJ for his holistic approach to revitalization, emphasizing economic growth, housing, employment, and entertainment.
