Morison Global has expanded its international network with the addition of Dutch accounting firm Koeleman Groep as a new member firm.

Headquartered in Hilversum, Koeleman has five other offices across the Het Gooi, Amsterdam, and Hague regions.

The firm offers a range of audit, accounting, tax and management consulting services, supported by nine partners and more than 150 employees.

It also has specialist offerings in ESG audit and advisory, international tax structuring, cross-border transactions, transfer pricing, expat tax services, and estate planning.

Koeleman has a diverse client base, with particular emphases on the healthcare, government, and not-for-profit sectors.

International Liaison partner Barry Damen and managing partner Edo de Jong will serve as the firm’s principal contacts.

Damen said: “The steady growth of Koeleman in recent years urged the need for a strong worldwide partnership.

“In analysing the possibilities, we found in Morison Global a reliable and ambitious international association which matched our DNA as entrepreneurs globally delivering high quality audit, accounting and tax services. Morison Global felt like a family from the first contact.”

Koeleman is set to complement Morison Global's other Dutch members - Hoek en Blok and Kallen Accountants en Adviseurs.

Morison Global CEO Ryan Piper said: “We’re thrilled to welcome Edo, Barry, and the team at Koeleman to the Morison family. With our new strategy taking shape, coupled with our impact initiatives, bringing in a large firm like Koeleman is testament to our strong DNA.

“The firm will be an excellent fit for the Association, through the services and expertise the firm provides, in addition to the Koeleman Groep culture and personality.”

In November 2022, Morison Global appointed new members across three regions. The company welcomed R&R Auditoria e Consultoria in Brazil; MSW Consulting Kft in Hungary; and Afrique Audit et Conseil in Mali.
