By 1985, he decided to found his own law firm called Aragón Audelo Abogados, handling all types of Labor issues, expanding the service to the collective area, working with Unions. Subsequently, other areas were integrated into the office ,criminal and civil, thus consolidating the quality of the service to its clients.

In 2006, he created a Federation of Trade Unions, which he represents, identified with the acronym of FESAM, that is integrated by various groups of workers of different sectors of the industry, having representation in all the country. One of the most important characteristic of FESAM is the autonomy, that means that it does not belong to any other unions, that is self-decision making and there is no influence by any political party, always ensuring the well-being of the workers and employers.

Currently, he is constantly updating and studying, taking different diplomas and courses in Labor, Tax, Judicial Remedy, Criminal and Human Resources areas, in institutions such as Libre de Derecho, Universidad Panamericana, Instituto Tecnológico Autónomo de México, Instituto de Estudios Superiores en Derecho Penal, Universidad Nacional Autónoma de México, Centro de Estudios en lo Penal Tributario, AC, Yale School of Management, Asociación Nacional de Abogados de Empresa, among others, in order to provide an excellent service. One of his last achievements has been the participation as a member of the Commission of Trade Unions of Mexico in the International Labor Organization (ILO) in Geneve, Switzerland.
