Special Announcement

NUSSBAUM and MGO Join Forces

New-York based Nussbaum, Berg, Klein & Wolpow, CPAs LLP (NUSSBAUM), a premier accounting firm for middle market businesses and high-net-worth individuals on the East Coast has formally joined the MGO global service platform.

Founded in 1990, NUSSBAUM adds a wealth of resources to MGO’s full spectrum of accounting, auditing, tax, and business advisory services for closely held entrepreneurial businesses and public companies. The firm’s team will augment MGO’s capability providing complex tax, audit, and advisory services to a variety of industries — including Fortune 500 companies, national corporations, local businesses, and family-owned businesses.

The former NUSSBAUM partners and team members will continue to operate from their Melville, New York office as the newest Long Island office for MGO. The combination with NUSSBAUM strengthens MGO’s presence on the East Coast and provides immediate access to the fast-growing cannabis markets and the concentration of high-net-worth individuals in New York City and beyond.

NUSSBAUM currently serves many of MGO’s core industry segments and expands our ability to serve a variety of other industries like manufacturing and distribution, real estate, construction, financial services, and family offices.
