Greven & Co was set up in July 1993 originally called Mildren & Associates until 1998 when the name changed to Greven & Co. Then in 2008 it was decided that because the two types of services offered, Accounting and Financial Planning had grown into their own unique services, it was agreed to change the business names to suit the services offered and hence Greven Accounting Services and Greven Financial Services were created.
