Ellis J. Mayer, Esq.


In his more than 30 years as a litigator, Ellis has emphasized a practice that includes all aspects of insurance defense litigation before the District Courts of the State of Colorado and the U.S. District Court including automobile related claims, insurance litigation, bad faith claims, legal malpractice, premises liability and dram shop liability claims, product liability and construction defect. His experience has reached the point that he is surprised not only that the younger attorneys in the office ask him for advice, but that he actually knows the answer.

Ellis prides himself on being able to understand which cases can be or should be tried. For that reason, he not only has a reputation in the legal community as someone willing to try cases, but is proud to say that in his automobile defense practice, a jury has never returned anything but a defense verdict, or a verdict substantially less than the offers of settlement. He has tried cases in the counties of Adams, Arapahoe, Boulder, Denver, El Paso, Jefferson, Larimer, Las Animas, Morgan, Routt, and Weld, and in the U.S. District Court.

Ellis has also been involved in appellate decisions that are part of Colorado precedent including ITT Specialty Risk Servs. v. Avis Rent a Car, 985 P.2d 43 (Colo. App. 1998), Allstate Ins. Co. v. Avis Rent-A-Car, 947 P.2d 341 (Colo. 1997), Martin v. Minnard, 862 P.2d 1014 (Colo. App. 1993), Mikes v. Burnett, — P.3d — 2013  WL 3430886, (Colo. App. 2013), AdvantEdge Bus. Grp. v. Thomas E. Mestmaker & Associates, Inc., 552 F.3d 1233 (10th Cir. 2009), and Town of Dillon v. Yacht Club Condominiums Home Owners Ass’n, 325 P.3d 1032 (Colo. 2014).

In addition to being admitted to practice in all State and Federal Courts in Colorado, Ellis is also admitted to the United States Court of Appeals for the Federal Circuit in Washington, D.C.  He is a member of the American Board of Trial Advocates, the Colorado Defense Lawyers Association, and the Arapahoe County and Colorado Bar Associations.

When he isn’t working, he works as a day laborer for his wife.
