Jacob was born in Peoria, Illinois. He graduated in the top 5 of his class from Fairview High School in rural Northwest Oklahoma in 1994. He and his brothers, Josh (twin), Matt and Adam were All-State Basketball players at Fairview during their time at the school and led their teams to multiple state tournaments and individual awards. Jacob comes from a long line of gifted and intelligent men in his family including his dad, Dave Diesselhorst, who was an all-conference college baseball player for the Bradley Braves in the Missouri Valley Conference in Peoria, Illinois in the 1970's and his grandfather, Emery Gregory, from Washington, Illinois, who was the founder and owner of Gregory Livestock and Quarter Horses.
Jacob went on from Fairview to Oklahoma State University where he was a pre-law major and went on to graduate with a BA in Political Science and a Minor in Business, with honors in May 1999. In August of 2000, Jacob was accepted and agreed to attend the University of Oklahoma College of Law in Norman, Oklahoma, where he regularly made the Dean's Honor Roll and also made a name for himself as a very outspoken and likable classmate. Jacob received his juris-doctorate degree from OU Law School in May 2002 and passed the Oklahoma Bar Exam in July 2002 to become an Oklahoma lawyer in September 2002. Jacob then went to work for a small insurance defense firm in Oklahoma City for just over two (2) years before joining Glendell Nix & Noble McIntyre of Nix & McIntyre, LLP, to begin representing personal injury and wrongful death victims in Oklahoma. In 2009, Jacob proudly joined Glendell Nix to form Nix Law Group, PLLC, with offices in Edmond, Oklahoma.
Jacob takes great pride in helping the victims and families of those who have suffered serious injuries and/or death due to another person or corporation's improper conduct obtain the justice and compensation they are entitled to. Despite being one of the younger attorneys practicing in these specialized areas of personal injury law in Oklahoma, Jacob has gained a reputation of respect and hard-work amongst his colleagues on both sides of the aisle and from Oklahoma judges. Jacob is also actively involved with the Oklahoma Association for Justice's (OAJ) legislative and political activities.
Jacob is also licensed to practice law in New Jersey having taken and passed the New Jersey Bar Examination in July 2008. With this added flexibility, Jacob has recently been selected as Of Counsel to the New York City/New Jersey Law Firm of Blau, Brown & Leonard (BBL). Jacob works closely with BBL on multiple high-dollar personal injury and other types of significant cases across the country.
