In 2002, Cimarron graduated cum laude with a BA in Government Studies from the University of Notre Dame. He worked at the Mexican American Cultural Center in San Antonio and the Austin office of U.S. Senator John Cornyn before heading to Ave Maria School of Law in Ann Arbor. In law school, he served on the Ave Maria Law Review as a senior editor and graduated magna cum laude with a JD in 2007. After passing the Texas bar exam, he began a three‐year clerkship with The Honorable George P. Kazen, U.S. District Court Judge for the Southern District of Texas, Laredo Division.

In Laredo, he became active at St. Peter's Catholic Church, volunteering and serving as a religious education teacher and youth minister. This ministry inspired him to discern the Catholic priesthood. So in 2010, he left his legal position and entered Assumption Seminary in San Antonio.  While in seminary, he completed a BA in Pastoral Ministry, graduating summa cum laude from the Mexican American Catholic College (MACC) in 2012. After graduation from MACC, he left seminary to attend to family responsibilities and resume his legal practice.

Cimarron's practice focuses primarily on Estate Planning, the process of crafting a thoughtful written plan to distribute one's wealth at death and manage it upon incapacity, and Probate, but Cimarron also handles Business Formation and simple Real Estate matters.

Cimarron's primary mission is to help people avoid the pitfalls of failing to plan for death and incapacity by educating them about their estate planning options, often bringing to light situations frequently overlooked, and encouraging them to take the initiative to plan now, so they or their loved ones do not have to pay later. Cimarron's goal is to make sure everyone he serves, regardless of background, has a professionally crafted estate plan that incorporates his or her values. With this plan in place, his clients can finally achieve the peace of mind that comes with putting their final affairs in order.

Cimarron regularly presents a FREE and informational Estate Planning Seminar to various churches and local associations, like the Knights of Columbus. If you would like to schedule Cimarron to present at your church, small group, or association, please contact our office for more information.
