I went to Dr.Duberstein hoping for relief from my chronic sinuitis. I went twice and waited over 3 hours both times. He prescribed additional nasal sprays and told me my cat scan did not show blockage. I've been on antibiotics non-stop and told him I want to repair my sinuses not just continue treating infections. Between his jokes he tells me my problem is psychological and prescribes more sprays and antibiotic. He never really explained to me why I can't stop getting sick, but somehow everything he told me contradicts what my allergist told me. I am canceling the third appointment and finding a different specialists. By the looks of his waiting room he treats only babies with ear infections. A side note, I don't think the clinic has custodial service. I've seen cleaner bathrooms in roadside gas stations. Totally disgusting on both visits.
