Origin: From Latin American Studies to Capital Defense
Gregory Kuykendall earned a B.A. in Spanish and Philosophy from the University of Colorado in 1983, an M.A. in Latin American Studies from Tulane University in 1985, and his J.D. from Northwestern University School of Law in 1988, before being admitted to the Arizona Bar in 1989. He built a bilingual (Spanish-English) criminal defense practice in Tucson handling state, federal, appellate, and habeas corpus matters, with a particular emphasis on death penalty defense and other serious felonies — work that grew, in part, out of his academic background in Latin American studies.
Practice Areas
Kuykendall accepted appointments for years as first-chair counsel on the Capital Murder Panel in Pima County and is designated Learned Counsel in federal death penalty cases. Since 2006, he has served as lead death-penalty counsel to the Mexican Foreign Ministry, directing the Mexican Capital Legal Assistance Program and, in that role, supervising roughly three dozen capital defense lawyers across more than a thousand cases and personally appearing in more than thirty state, federal, and international jurisdictions on behalf of Mexican nationals facing capital charges — including admission as lead defense counsel before the Special Tribunal for Lebanon. Separately, he has represented the families of people killed in police-use-of-force incidents in civil wrongful-death matters.
Track Record
Capital and felony case outcomes are a matter of public record in ways ordinary criminal matters often aren’t, but Kuykendall’s caseload spans confidential international and diplomatic representations that aren’t independently citable in the way a published appellate opinion is. What is publicly documented: his firm’s own account of representing the families of decedents in police-use-of-force and wrongful-death matters, including cases arising from the 2020 in-custody death of Carlos Adrián Ingram-López involving the Tucson Police Department, the 2021 fatal shooting of Anthony Cano by Chandler police, and the family of University of Arizona professor Dr. Thomas Meixner following his 2022 murder on campus.
Past-Results Disclaimer: Every case is different, and no past result guarantees a similar outcome in any future matter.
Client Voice
Kuykendall has no numerical rating yet on Avvo, but carries direct peer endorsements there — fellow criminal defense attorneys describe him as highly skilled and well respected in the legal community. A national profile of his career quotes a San Diego capital defense colleague describing his “encyclopedic knowledge of the law” and calling him strategic and dogged in representation.
Community
Kuykendall is a former member of the Board of Directors of the National Association of Criminal Defense Lawyers and a Life Member of that organization. He is a Phi Beta Kappa member and has given more than 100 presentations across the U.S., U.K., Mexico, and Argentina — in both English and Spanish — on capital litigation and related legal topics, including training seminars for consular protection officers and continuing legal education programs for both criminal and civil practitioners.
Recognition
Kuykendall holds Arizona’s Board-Certified Criminal Law Specialist designation — one of the smallest specialist pools in the state. He is A-V rated by Martindale-Hubbell (peer review), listed in the Bar Register of Preeminent Lawyers, and has been named a Southwest Super Lawyer every year since 2007 — a peer-influenced, research-driven selection, not a purchased listing.
The Arizona Legal Backdrop
What follows is general legal information, not legal advice.
Arizona’s felony sentencing structure, including the state’s capital sentencing procedures, runs through A.R.S. §§ 13-701 through 13-719. Controlled-substance offenses are classified under A.R.S. § 13-3401 et seq. Since January 2023, certain arrest, charge, and conviction records can be sealed under A.R.S. § 13-911, distinct from the older “set aside” remedy under A.R.S. § 13-905. For foreign nationals specifically — central to much of Kuykendall’s capital work — the Vienna Convention on Consular Relations (Article 36) creates a separate, federally-grounded notification right that has been litigated in several of the cases he has written about professionally.
The Awesome Attorneys Assessment
Kuykendall represents a genuinely rare category within Arizona criminal defense: an individually board-certified specialist with a two-decade diplomatic role directing capital defense for a foreign government, published legal scholarship, and international courtroom experience most Arizona attorneys — criminal or otherwise — simply don’t have. That makes him a strong fit for the most serious felony and capital matters, particularly involving foreign nationals or cross-border issues.
The honest caveat: this is a highly specialized capital and serious-felony practice, not a general criminal defense shop geared toward routine misdemeanors or first-time DUI matters — clients with more everyday charges may be better served by a firm built around higher case volume.
