Sergio Pareja joined the UNM law faculty in 2005 after nearly nine years in private practice in Colorado and Indiana. Most recently, Pareja was a partner in the tax department at a large Denver law firm. While in private practice, he specialized in federal individual and corporate income tax planning, state and local tax matters, and estate and gift tax planning.

At the UNM School of Law, Pareja primarily teaches courses in the areas of business, tax, and estate planning. Since he started teaching at UNM School of Law, he has taught Federal Income Tax, Contracts, Practicum, Estate and Gift Tax, Taxation of Business Enterprises, International Business Transactions, Wills & Trusts, and Estate & Retirement Planning. He also has taught in the law school's Business & Tax Clinic.

Pareja's recent research interests include estate and gift taxation, with a focus on liquidity issues. In addition, Pareja currently is exploring ways to make our federal income tax system simpler and more equitable in connection with transfers that take place at death.

Pareja has lived with family in Colombia and Venezuela, and he is extremely dedicated to giving students the opportunity to live in other countries while studying law. He has taught in and directed the Guanajuato Summer Law Institute in Guanajuato, Mexico. Pareja is fluent in Spanish, and he also spent a year teaching Spanish law students as a visiting professor at the Universidad Rey Juan Carlos in Madrid, Spain.

Pareja also is the founding director of the ABA-approved Madrid Summer Law Institute. Professor Pareja continues to direct and teach in this successful program, which offers students the opportunity to study law in Spain during the month of June.

Pareja is a highly dedicated teacher. In 2011, he was identified by The National Jurist as one of the top law teachers in the country: The Bucket List: 23 Law Profs to Take Before You Die. In 2013, Pareja was honored by the University of New Mexico with a university-wide "Outstanding Teacher of the Year" award.

In addition to teaching at the University of New Mexico, Pareja teaches in the University of Alabama's tax LL.M program. He was recruited to be part of a "Dream Team" of distinguished professors from across the nation to teach in this innovative program.

Outside of his interests in the law, Pareja is a dedicated guitarist who has performed at Swallow Hill in Denver, as well as at numerous convalescent hospitals in the Denver area. In Albuquerque, he has performed extensively at UNM Hospital through the innovative Arts-in-Medicine program. Pareja is even known to play his guitar in class on occasion.
