Lee Schlesinger

Instructor
Lee Schlesinger has a BA and Masters in computer science from Queens College, and has held numerous positions within the IT industry, including at AlayaCare and the NYC Department of Education.

The more he understands how the world works, the better he can make use of what it offers. Computer numbers are not the same as people numbers. To a person, one over one hundred is just .01; but to a computer, it continues for many places. Math has never left his life.
