As an aller­gy, asth­ma and immunol­o­gy spe­cial­ist, I strive to pro­vide my pedi­atric and adult patients in the Joli­et, Naperville and New Lenox com­mu­ni­ties with the best care pos­si­ble. Aller­gies and asth­ma can have a tremen­dous impact on your dai­ly life. Whether you’re strug­gling with chron­ic sinus symp­toms, food aller­gies or skin rash­es, my goal is to work col­lab­o­ra­tive­ly with each patient to iden­ti­fy their spe­cif­ic aller­gens and devel­op a treat­ment plan best suit­ed to their indi­vid­ual needs. In order to achieve the best out­comes, it’s essen­tial that patients are includ­ed in the deci­sion mak­ing process and feel well-informed and com­fort­able, both with me and their care plan.
