NESAD™ Corporate Advisors: Conceptual Development and Ongoing Professional Mentorship

NESAD™ is commonly asked, “Who’s idea was NESAD™? From whence did NESAD™ come?” The actual concept of a national real estate due diligence depository-archive originated and evolved in 2012-2014 during numerous long distance telephone discussions (often lively) between real estate professionals practicing in the East and Southwest U.S. However, the applied, real world, critical input developed over the same period during market survey conversations with commercial real estate lenders, banking relationship managers, brokers, loan originators, real estate investors, and property owners who grapple with real estate due diligence matters daily. The NESAD™ Map Search™ program utilized by the NESAD™ depository staff and the archive subscriber-depositors was imagined, developed, and implemented over a three year period.

During NESAD’s™ conceptual development, Witt provided perspective into how NESAD™ integrates into the due diligence industry’s inspection, assessment, and valuation practices. An experienced environmental risk assessor practicing in the Mid-Atlantic and Northeast, Witt investigated how NESAD™ would transform environmental and property condition assessment (PCA) practices. Witt holds a B.A. degree in Geography from Towson University.

Currently an experienced environmental risk assessor practicing in New Jersey, Rachael was at the time a real estate industry newcomer and thus was able to provide “industry outsider” insight on NESAD™. Rachael served as a “think tank” participant with NESAD’s™ developers. Rachael holds a B.A. degree in Environmental Sustainability-Science from Notre Dame of Maryland University.
