independents for independents

All organizations need a strong compass, or set of core values, that guide the direction of the business.  Since our inception, we have been strongly aligned with independent eye care professionals.  Among our core values is the belief that the strength of independent ECP's depends on a strong partner that stands behind them, fights for common values, and stays true to its commitments.
