About Marcos D. De
Marcos D. De Hoyos took a conventional path into the law but carved out a practical niche early. He studied at Texas A&M University in College Station, where he earned a Bachelor of Arts. He then moved to Nashville and completed his law degree at Vanderbilt University Law School in 2020.
After graduating, De Hoyos began practicing in federal and state courts. He is admitted to the bar in Texas and holds admissions to several federal district courts. Those include the U.S. District Court for the Southern District of Texas, the Northern District of Texas and the Western District of Texas, as well as the Northern District of Illinois on the general bar. He has handled courtroom filings and procedural work across those jurisdictions.
Colleagues describe him as methodical and direct in his courtroom work. He regularly prepares briefs and manages filings in multi-district settings. He has experience taking part in hearings and arguing motions in federal court. His work involves coordinating with opposing counsel, drafting pleadings and responding to complex procedural challenges that federal litigation often presents.
De Hoyos’s resume does not hinge on a single headline matter. Instead, it reflects steady work across regional federal dockets. He has navigated the practical demands of practice in both Texas and Illinois federal forums. That has required attention to differing local rules, timetables and procedures. He adapts filings and courtroom strategy to the requirements of each district.
Outside the courtroom, he draws on the analytical training from Vanderbilt and the broader undergraduate perspective from Texas A&M. The mix of academic and practical experience informs how he approaches discovery disputes, scheduling orders and pretrial preparations. He communicates plainly with clients and opposing counsel, keeping filings focused on the relief sought rather than rhetorical flourishes.
As of 2026, De Hoyos maintains active admissions in Texas and several federal district courts and continues handling matters that require federal-court practice in those jurisdictions. He currently concentrates on federal court litigation and related procedural work in Texas and the Northern District of Illinois.
