It was time for a change for Graciela Castro. After years spent working in finance, she realized that her fast-paced career had hobbled her health, relationships, and ability to sit still for a whole rendition of "99 Bottles of Beer on the Wall." So Castro learned to style hair, something she knew she would love once she observed how much a chic cut could lift a person’s spirits. It wasn't long before she opened Graciela's Salon. There, staff members apply the skills they learned at international style conferences to perform services with Paul Mitchell hair treatments or Gelish or Essie nail-polish hues. To enhance the mind-body experience she values, Castro makes clients feel at home by providing such complimentary beverages as wine and coffee, as well as free wireless-Internet access.
