About Jessica Mandelbaum
I am a senior real estate investor and asset manager focused on the ownership and execution of multifamily investments across multiple U.S. markets.In my role as Chief Operating Officer, I oversee acquisitions, asset management, and portfolio-level strategy with a hands-on approach to value creation—spanning capital planning, financing, operations, dispositions, and long-term portfolio optimization.I work closely with sponsors, lenders, brokers, and property management teams to navigate complex assets, align incentives, and drive performance in both stable and transitional environments. My background spans the full investment lifecycle, which allows me to bridge strategy with execution and make informed, pragmatic decisions.I am known for being direct, thoughtful, and collaborative—focused on building long-term relationships and finding durable, win-win outcomes.In parallel with my professional work, I am deeply involved in Cure Rare Foundation, a nonprofit dedicated to advancing research and awareness for rare diseases. The mission is personal and has shaped how I think about leadership, responsibility, and impact—both inside and outside of real estate.I value strong partnerships, clear communication, and disciplined decision-making. Always open to thoughtful conversations with operators, capital partners, and industry peers.
