Ms. DeOliveira graduated from St. John’s University, Staten Island Campus in 1989 with a Bachelor of Science degree in Criminal Justice. She went on to earn her law degree from St. John’s University School of Law, graduating in 1992. From there, she was admitted to practice and was hired by the Kings County District Attorney’s Office as an Assistant District Attorney where she worked from 1992 to 1997. In 1997, Ms. DeOliveira left the Brooklyn D.A.’s Office to start her own private law practice on Staten Island, which included civil claims as well as criminal defense work. While working full-time as a private attorney, she had her two daughters in less than a three-year span before returning to being a prosecutor in 2000, this time in the Richmond County District Attorney’s Office under the Honorable William Murphy. During her career at the Staten Island D.A.’s Office she has worked as the Deputy Bureau Chief in the Special Victims Bureau from 2005 to 2008 and then as the Deputy Bureau Chief in the Trials Bureau until 2010, when she was then named Chief Trial Counsel to continue her love of trial advocacy in mentoring the junior assistants with their trials. After the retirement of former Special Victims Bureau Chief Yolanda Rudich, in 2014, Ms. DeOliveira was asked to return to the Special Victims Bureau as the new Bureau Chief, a position she held until July 2017 when she was promoted to the Executive Bureau as Chief Trial Counsel.
