In 1999, Serzedelo founded the radio programme "Vidas Alternativas", which was the first programme in Portugal to discuss LGBTI issues. It was initially broadcast on Voxx radio and aired on several university and local radios throughout the country. Nowadays the program is broadcast online at the MegaWeb website. Recently he created the programme Vidas Alternativas Brasil, in order to reach the Brazilian audience.

On 28 June 1997 Serzedelo founded the Opus Gay Association, whose goal was to defend the human rights of sexual minorities. With the support of the Commission for Citizenship and Gender Equality and within the scope of the National Strategic Reference Framework, Serzedelo created an extension of Opus Gay against domestic violence and homophobia in Évora.
