It has long been known that corrections motivated by chiral symmetry arguments give important contributions to hadronic observables. Results of incorporating pion loop corrections to the NJL Model - a constituent quark model - are presented here. A particular parameter set yields a good fit to the nucleon charge radius $<r_N^2>$ and a slightly low prediction of the nucleon magnetic moment $\mu$.
