Practices In: Bloomingdale, Itasca
Patients Seen: All Ages

I chose to become an aller­gy and immunol­o­gy spe­cial­ist because I love help­ing peo­ple regain con­trol over their lifestyles when nav­i­gat­ing aller­gies and asth­ma. Treat­ment options in this field are con­stant­ly expand­ing, and I strive to offer evi­dence-based and spe­cif­ic treat­ment options to each individual.
