History
Established in 1970.
Our law practice was initially established by Dennis O’Brien in Walnut Creek in 1970. The partnership, O’Brien & Sullivan, was formed in 1983. Dennis O’Brien and Edward Sullivan purchased The Morgan Building in downtown Walnut Creek in 1990 and our offices have been located there ever since. Christina Van Ness joined the firm in 2009.
