JP Prentiss


JP focuses his practice on family law cases in Boulder including: complex dissolution and allocation of parental responsibilities cases, and the modification of previously entered orders. When resolving family law disputes, Mr. Prentiss focuses on crafting resolutions that not only meet his clients’ needs, but also ensures that the best interests of the children involved takes top priority.

Since his admission to the bar in 2005, he has tried over twenty jury trials, handled countless contested motions and other hearings and successfully negotiated settlements in hundreds, if not thousands more.

From an early age JP knew he wanted to continue his family’s legacy as an attorney. His passion for justice and helping those in need has only continued to grow since then. JP grew up in Texas where he attended Southwestern University in Georgetown and earned a BA in history and theater. After college he moved to Denver, working as a theater technician prior to attending the University of Denver Sturm College of Law.

During law school he became a teaching assistant for first year criminal law students, and interned with the Denver District Attorney’s office in both the appellate and juvenile divisions. During his third year, while interning in the juvenile division, JP was recognized by his professors for excellence in Criminal Law drafting and Trial practice. After graduating from law school JP was sworn in as a Deputy District Attorney for Denver where he handled hundreds of cases ranging from traffic and misdemeanor matters to first degree murder.

It was at the DA’s office, while again working in the juvenile division, that JP developed a passion for helping children who have become involved in the justice system. After leaving the District Attorney’s Office, this passion naturally focused his practice on parental responsibility actions where he is able to use substantial litigation and negotiation experience to ensure that cases are resolved and that the best interests of the children involved takes priority. His extensive trial and negotiation experience also benefits his clients in handling financial matters, ensuring the best possible results for clients no matter how big or small their cases may be.

While not helping clients JP spends time with his family, including two biological children, two step-children, and a Shiloh Shepherd named Sif. Mr. Prentiss also sits on the board of Pop Culture Classroom, an organization dedicated to improving literacy through graphic literature and pop culture.
