This article investigates the theoretical study of steady stagnation point flow with heat transfer of a micropolar second grade fluid towards a stretching surface. The governing equations of micropolar second grade fluid are presented. The governing partial differential equations are converted into ordinary differential equations. The resulting coupled nonlinear set of ordinary differential equations are sucessfully solved analytically using Optimal Homotopy analysis method. Graphically results are shown. Numerical values of skin friction coefficients, and heat flux are computed. It is found that velocity at a point increases with increasing microrotation parameter for strong as well as weak concentration of the particles. Heat transfer is increasing function of the elasticity parameter. Comparison with previously published work is performed and excellent agreement is observed for the limited case of existing literature.
