The Holley Community Fund is an ongoing program that donates to a different local nonprofit organization each month and is underwritten by Holley Heating & Air Conditioning, Aiken's leading provider of heating and air conditioning products. Millions of children and adults live each day with uncontrollable shakes from essential tremor (ET), the largest movement disorder in the world. It can begin at any age, from 1 to 100. DSF's mission is to educate and increase awareness about the people afflicted with ET — especially children — and provide medical research grants to find the cause and a cure for ET.
