Renee Klaric, program manager for University Hospitals Addiction Services, will speak to the Aurora Chamber of Commerce from 11:30 a.m.to 1 p.m. Wednesday at the Bertram Inn and Conference Center, 600 N. Aurora Road.

Klaric, who has a history of helping patients in a variety of settings, will speak about the ways and reasons to treat addiction as a chronic disease rather than a one-time malady. The cost of the luncheon is $25 for Aurora Chamber of Commerce members and $30 for non-members. To register, call 330-562-3355.
