Nelson Del Rio

Nelson has been with Blokable from the beginning – as an advisor since the company’s founding and as co-CEO since 2017. Nelson graduated from Harvard Law School in 1987 and has been an active and continuous member of the California State Bar since 1987. Nelson began his career as a Mergers and Acquisition Attorney at Skadden, Arps, Slate, Meagher & Flom and then went on to become an active impact investor, developer, and philanthropist.
In addition to his retail, land and other type of real estate acquisitions and development, Nelson is best known for his efforts in early single asset securitization, as well as the creation of the public-private partnership, design-build paradigm in use today in connection with government and other facilities. More specifically, Nelson designed the structure and drafted all related documents in connection with the creation of credit tenant lease bonds for a public-private waste transfer facility and a private company’s headquarters and manufacturing facility. In each case, Nelson acted as a principal in bond creation and then resold the bonds to institutional investors. Each of the transactions was among the earliest commercial real estate single asset securitizations. Nelson went on to apply his prosperity-centric development model to commercial real estate where he utilized a novel design-build-finance-manage-operate structure to realign interests of all participants in the development process which drastically reduced risks, lowered costs, cut development time, greatly increased build quality and finishes, provided a better occupant experience, and resulted in highly efficient and resilient building, while also creating wealth in the community at large. To accomplish this outcome, he structured the first rated, insured and publicly traded off-balance sheet financings of public-private-civil society partnerships (P3s) developing public facilities. In total, Nelson structured, designed, financed, and developed three welfare office projects at a cost of approximately $145 million and gave away the residual value of the projects to impacted communities through not-for-profits he administers to this day.
These early P3 efforts became the prototype for an industry of design-build-finance-operate-manage projects around the world in the years following. Through application of his prosperity-centric wealth creating model, Nelson effectively used capitalism to privatize risks and socialize wealth creation — later P3 efforts often did the inverse. Nelson is bringing this same prosperity-centric wealth creating structure, process, and creativity to the implementation of Blokable’s approach to creating housing wealth for its shareholders and for the underserved.
