In this article, the Parker-Sochacki method is extended to solving boundary values of N-th order differential equations. By recasting the problem as a system of constant coefficient polynomial ordinary differential equation, the coefficients of the power series solution is computed iteratively. The closed form solution is obtained by employing Laplace-Padé series summation as an after-treatment procedure. Application of the new technique to various examples elucidated the accuracy and reliability of the approach.
