Jeff grew up in the Portland area in the Pacific Northwest and has resided in Oregon for more than 20 years.

Jeff continued to provide extensive legal research and draft crucial motions and memorandums of law for various state and federal cases for Mark Cogan during his three years in law school, as well as trial preparation and support. While in law school, Jeff was a member and elected Business Editor of the Willamette Law Review, wrote for Willamette Law Online, and achieved High Paper honors in Comparative Constitutional Law, Law and Education, and Oregon Criminal Procedure and Practice, taught by Paul De Muniz, former Chief Justice of the Oregon Supreme Court. Jeff also achieved publication of a Law Review Article in the Willamette Law Review during his third year in law school, titled Faith Healing Prosecutions in Oregon: The Fine Line Between Parental Constitutional Rights and Governmental Interests.
