SMELL & TASTE TREATMENT AND RESEARCH FOUNDATION,

SMELL & TASTE TREATMENT AND RESEARCH FOUNDATION, LTD. Alan R. Hirsch MD in Chicago, Illinois, is dedicated in the research on the effects of loss of sense of smell and taste on human emotion, mood, behavior, and disease states. We believe that restoring damaged senses restores not only a person's self-esteem, but also his or her faith in others and the society. With our more than 30 years of experience, trust us to help you detect and overcome these problems.
