The annual Knoxville Heart Gala celebrates the work and mission, donors and volunteers and the lives saved and improved because of everyone’s efforts. The 2015 event chair is Eddie Mannis, and the theme is Thirty Years of Service. Cocktails and silent auction begin at 6 p.m., followed by seated dinner and live auction beginning at 7:30 p.m. Elenowen, who appeared on the inaugural season of NBC’s “The Voice,” will perform, and there will be dancing until midnight with DJ Jim Ogle.

The 30th Annual gala will be held in remembrance and honor of Bob Wilson, who passed away suddenly last March from undetected heart disease.
