The firm has trajectory long track record advising associations of professionals such as nurses, doctors, lawyers, administrative clerks or notaries. During this time, the firm has counseled theses associations to ensure their proper functioning, appealing those regulations that impacted their professional interests, defending their interests in constitutional conflicts, drafting the bylaws of these associations to, ultimately, ensure their proper functioning and funding.

Baño León has also defended the interests of many professionals in their conflicts with professional associations whose admission is necessary to practice a profession. For example, we have obtained access to the profession for several groups of engineers as well as monetary compensation for the time they were deprived of practicing their profession.
