We study the Neumann and regularity boundary value problems for a divergence form elliptic equation in the plane. We assume the gradient of the coefficient matrix satisfies a Carleson measure condition and consider data in L^p, 1 < p \leq 2. We prove that if the norm of the Carleson measure is sufficiently small, we can solve both the Neumann and regularity problems with data in L^p. This is related to earlier work on the Dirichlet problem by other authors.
