About Keith G.
Keith G. Oliver built a legal career that moves between courtroom steadiness and steady client work. He is the kind of lawyer who stays practical under pressure. His path is straightforward: solid schooling, steady firm work, then his own practice.
He completed undergraduate studies at Coastal Carolina University and earned his law degree from Seton Hall University School of Law. Those years prepared him for a practice split between two states. He is admitted to practice in both New York and New Jersey.
Oliver began his legal work as an associate at the Law Offices of Jonathan Marshall in 2010. The early years focused on learning case preparation, client interviews and courtroom procedure. He handled research and wrote motions while building a base of trial experience that would shape his later work.
In 2015 he became a partner at Marshall, Bonus, Proetta & Oliver. That step marked a move into shared leadership and heavier trial responsibility. Two years later he joined Proetta & Oliver as a partner, where case management and courtroom strategy remained central to his role. These positions gave him repeated exposure to criminal matters across the region and to the logistics of running a practice alongside litigation.
He later established Keith Oliver Criminal Law, where he is listed as a partner. The firm carries forward the thread of criminal defense that runs through his career. He is known in professional circles for steady courtroom presence and careful case analysis. Colleagues and clients encounter an attorney who prefers direct answers over legal flourish.
