Dr. Carolyn Siegal takes care of the well-heeled—literally. She's a podiatrist in Beverly Hills, where she's also launched her own collection of foot care products. After seeing patients who picked up infections from unclean nail salons, she launched the Dr. Carolyn Collection, a line of nail supplies meant to provide a safer pedicure.
