This certified public accounting and management consulting firm is popular among employees for fostering a creative workplace, but annual company-sponsored trips to tropical destinations -- Jamaica in 2011, Punta Cana in 2012 -- probably helps. Founded in 1991, the Sparks office is home to 237 employees working in a casual environment. During busy season, the company provides healthy snacks, on-site yoga, massages, dry-cleaning services and an ice cream cart. "I am encouraged to make decisions both independently and as a team," one employee said. "My opinions are heard and respected at all levels. I truly have a work/life balance and feel appreciated. I am able to collaborate with all teams and levels to get the job done. I have never witnessed such high energy and helpfulness on such a broad scale. It is so refreshing."
