David Graham began practice on his own account in Panmure in 1984 as David Graham Law Office.
In February 1998 the firm had grown significantly, so David and the team relocated to 13 Queens Road, Panmure (the old Westpac building).
The growth of the firm continued and in January 2004 David was joined in partnership by Christine Ding.  At the same time, the firm changed its name to DG LAW. In September 2017 Kelly McCullough joined David and Christine as a Director and in December 2018 relocated to new premises at 54 Lunn Avenue, Mt Wellington. The firm is now one of the largest in the Eastern Suburbs, and undertakes a broad range of legal work:
To ensure the firm kept pace with the needs of its clients, in 2008 David started a mobile legal service.  This service provides for our mobile lawyers to meet with our clients after hours, at a time and place convenient to you.
