Raphael began his career in real estate in 2010 with the founding of Lantower Realty and Property Management, which rebranded as LanTree Developments in 2017. Initially focused on the acquisition of revenue-producing multifamily assets in New York, the company accumulated a portfolio of distressed residential and retail assets, which, under Raphael’s leadership, were successfully repositioned, revitalizing neighborhoods and delivering much-needed, attainably priced housing to the market. In recent years, Raphael has expanded LanTree’s scope of services to include the acquisition and management of development projects, amassing a project pipeline of more than a million square feet in key metropolitan markets across New York and New Jersey.
