Cheyenne Kiernan

Cheyenne is a qualified US lawyer with criminal trial experience who works as a consultant to the firm. Cheyenne’s work for the firm is focused on the largest and most complex cases, those requiring input from a number of lawyers. 

After completing her Undergraduate Studies at the University of New Mexico (B.A. - Psychology & Criminology, magna cum laude, 2005) Cheyenne attended law school at Gonzaga University School of Law (J.D. 2009). Cheyenne’s legal career commenced at a busy and well reputed defence practice in Spokane, Washington State. Cheyenne also worked as an assistant district attorney, in Farmington, New Mexico, where her efforts earned an award reflecting the improvement to her department’s success rate in Court.

Cheyenne moved to London in 2011 and has worked with this firm since her arrival. Along with her relaxed and direct American approach, Cheyenne brings an exceptional eye for detail to any case and has a formidable memory. There is no division between barristers and solicitors in the US, and Cheyenne is therefore a fusion of the two roles.

Cheyenne remains a member of the Bar in the state of New Mexico and continues to work for US company, Legal Research Pros (“LRP”).  LRP provides legal research and drafting expertise to other attorneys (much as a barrister may support a solicitor’s work here).  Cheyenne’s experience gained through LRP has expanded to include both civil and criminal matters - in a variety of US jurisdictions – state and federal.  

If you are a law firm and you require guidance as to the law in the United States you may wish to contact Legal Research Pros with whom we have an association.  You can contact them here: legalresearchpros.
