In 1992, Ms. Heredia began her legal career with the Argentine firm of Estudio Beccar Varela. In 2008 she formed her own firm HOLT Abogados with three female partners. As Ms. Heredia told Who's Who Legal, "It was a decision I had been thinking about for some time. Although I was at a great stage in my career at Beccar Varela, I decided it was time to follow a different path."
Holt Abogados is a boutique firm focusing on natural resources and environmental matters along with corporate, regulatory, and financial matters.
Ms. Heredia has served as a trustee with the Rocky Mountain Mineral Law Foundation. She was recently elected to the position of secretary of the Foundation's Board of Directors. She is currently senior vice-chair for the International Bar Association's Section on Energy, Environment, Natural Resources and Infrastructure Law Mining Law Committee.
Don Smith, Director of the ENRL Program said, "Florencia Heredia is an inspiration for all who meet her. She is smart, hard-working, energetic and above all highly respected by her colleagues. She is, without question, one of the top mining law attorneys in the world, and her career should be an example to all about the success one can achieve through hard work and determination. All of her friends at Denver Law are thrilled with this recognition."
Ms. Heredia and Luis Carlos Rodrigo, attorney with Rodrigo, Elias & Medrano Abogados in Lima, Peru, teamed up to teach Latin American Mining Law at Denver Law.
