Mattiacio Orthodontics, 1393 Hathaway Drive, Farmington, will host a Halloween Candy Buy-Back donation drive from 8 a.m. to 5 p.m. Nov. 1 through Nov. 4.

The program will pay $2 for every pound of unopened candy. The candy will be shipped to troops overseas for them to utilize as an outreach to children in their location. A large portion of the candy will go toward Happiness House in Canandaigua to use for its Bowl-a-Thon event.
