William MacPherson joined the UNM law faculty in 1970 to establish a clinical law program, at the time a new concept for legal education. During the next 14 years, he built an innovative program that offered students practical experience prior to graduation. By the time he stepped down, the clinic was a required part of the Law School's legal education and one of the top clinical programs in the country.

While continuing to teach in the clinic in the mid-1980s, MacPherson also wrote a DWI Prosecution Manual and a DWI Trial Notebook. Throughout his career, he has spent time as a visiting professor at the University of Philippines School of Law, at the University of Guanajuato and the University of Guadalajara. He also has presented lectures at the University of Granada in Spain and the University of San Carlos in Guatemala.

His interest in Mexico led him to establish the UNM Law School's Guanajuato Summer Law Institute in 1989 which he continues to direct. MacPherson, who is fluent in Spanish, focuses his research interests on Latin America, in particular, on the role of the lawyer in Mexico. In that area, he has collaborated on a number of publications with Mexican law professors. In 2002, he co-taught the concept of clinical education to a group of law professors from Colombia.

MacPherson remains involved in the clinic, teaching a course every semester, bringing to the program his enthusiasm and experience.
