He is AV rated by Martindale-Hubbell, which is the highest possible peer-reviewed rating indicating very high to preeminent legal ability and very high ethical standards. He is a legal specialist certified by the State Bar of Arizona in Personal Injury and Wrongful Death Litigation. In addition to handling his own active caseload, Mr. Osborne manages nearly twenty-five attorneys who also devote their law practices exclusively to the representation of injured consumers. Mr. Osborne actively litigates his own cases. Mr. Osborne’s personal cases consist of personal referrals, large catastrophic injury cases, and cases that may not involve catastrophic injuries, but that involve unusual issues or problems that require his direct attention. Examples of Mr. Osborne’s catastrophic injury-type cases would be Yniguez v. DaimlerChrysler, a case Mr. Osborne tried to a jury in Nogales, Arizona. The jury award totaled $6.2 Million before application of comparative fault, and over $3 Million afterwards. Another would be Rosser v. Greenehaven Development, where a jury awarded Mr. Osborne's clients a verdict in excess of $1 Million on behalf of a family whose young son asphyxiated in a sand pit in Northern Arizona, one of the largest civil verdicts in that region of Arizona. Many of Mr. Osborne’s cases involve claims against major manufacturers that result in confidential settlements. One example is Harlow v. DaimlerChrysler, resolved days before trial in Federal District Court in Marshall, TX in August, 2006. Mr. Osborne has achieved confidential settlements with many major manufacturers including but not limited to Bridgestone/Firestone, Yokohama Tire Corporation, Ford Motor Company, and General Motors Corporation. Mr. Osborne has an active appellate practice. In recent years, Mr. Osborne has prosecuted a number of appeals. An example of his appeals work is Philadelphia Indemnity v.

Mr. Osborne has also directed hundreds of cases in federal multi-district litigation involving defective substances. For example, Mr. Osborne personally directed the firm’s litigation against Showa Denko, Inc. arising from this company’s manufacture of a defective health food supplement, L-Tryptophan.
