Robert Dumont

After having practiced for over 30 years with large organizations—first as a partner in Baker & McKenzie and then as the leader of Deloitte Tax LLP’s international private client practice—Robert has launched his own specialist law firm called, cleverly, Robert Dumont PLLC, and promptly appointed himself as head of the practice. Robert advises on a broad range of tax and estate planning issues relating to the cross-border activities of private clients and international family offices. As a small independent firm, Robert enjoys the freedom from client conflicts that can restrict larger organizations and the freedom to act in a fiduciary capacity where appropriate.
