Elisabeth M.W. Trefonas, ESQ.

Elisabeth M. W. Trefonas, graduated from California Western School of Law and moved from San Diego, California, to Jackson Hole, Wyoming, in May 2005. Shortly thereafter, she opened her private practice determined to provide exceptional legal services and access to the justice system for every member of her community.

Originally, as one of only three attorneys with expertise in immigration law in the entire state of Wyoming, and the only immigration attorney on the western side of the state, Ms. Trefonas' client base expanded rapidly. Additionally, because Ms. Trefonas was the only Spanish/English speaking attorney in the region (until others joined her firm), her practice provided and continues to provide access to the legal system for a severely under-represented segment of the population. In fact, the Spanish-speaking community makes up almost 15% of the population in Wyoming and an estimated 30% of the population in Jackson Hole.

Andrew Hardenbrook, ESQ.

Andrew Hardenbrook joined Trefonas Law in 2018 with a desire to use his more than a decade of legal work experience to advocate for immigration rights.  After graduating from Vanderbilt School of Law in 2007, Mr. Hardenbrook clerked for one year with the Arizona State Court of Appeals.  Mr. Hardenbrook then was employed as an associate attorney for more than seven years with a large law firm in Phoenix and Salt Lake specializing in corporate bankruptcy proceedings.  In 2016, Mr. Hardenbrook left the practice of law to become a special agent with the Federal Bureau of Investigation in the Los Angeles Field Office.  After more than two years with the FBI, Mr. Hardenbrook returned to the practice of law and moved from Los Angeles to Jackson in 2018 to be with his wife, Dr. Jacqui Hardenbrook, who is a pediatrician in Jackson.  He is proficient in Spanish and basic Portuguese.

Outside the office, Mr. Hardenbrook enjoys skiing, hiking, and playing golf and tennis.

Mr. Hardenbrook is admitted to practice law in the Arizona, Utah, and Wyoming state courts.
