What makes a company appealing to potential employees depends on who you ask. Some common answers, however, remain consistent across the board: flexible hours; substantial vacation days; quality insurance benefits; retirement packages; a strong pool of coworkers and management.
Other draws are the intangible perks: a collaborative work environment; a sense of feeling appreciated; room for creativity and out-of-the-box thinking; upward mobility.
A great company combines them all, the tangible and intangible, to create a situation where employees look forward to coming to work. Happier employees mean higher retention, better quality work and products, and a generally healthier environment for everyone.

Unique to every workplace is the combination of its history, its operations and its mark in the community and state.
