Contact Kathy Vu at OHSU for information. OHSU provides dental services for special needs kids. They are experienced with special needs kids and extremely patient and kind. Ambiance is non-existent and parking is a drag. There are usually 2 free clinic days per year, in July and December, sponsored by the Grottoes of North America - Humanitarian Foundation. Call OHSU about a month ahead to see if they are scheduling. The Grottoes also sponsors free dental care for children up to age 18, if they meet criteria showing that they are at least 2 years developmentally delayed.
