The Firm

A Long Island firm with a national reach.

For more than thirty-five years, CostaRothbort has provided audit, tax and advisory services from our Melville headquarters to family-owned and closely held businesses, labor unions, the construction and real estate industries, not-for-profits, professional firms and high net-worth individuals.

Beyond traditional accounting, we help clients secure surety bonds and bank financing, review their operations and plan for the long term. As a member of BDO Alliance USA, we can draw on national resources while you keep working with the same partner.
