Diversity & Inclusion

VPBG is committed to promoting a safe and inclusive environment, where everyone can feel free and respected, regardless of his/her/their race or ethnicity, culture, faith and spirituality, age, gender or sexual orientation. The firm nurtures a sense of belonging, cooperation and support among its members, aware that the plurality of ideas arising from a truly diverse place to work is an invaluable asset.

VPBG counts with its own D&I Committee called VPBG+ a program to support and strengthen local efforts in order to create opportunities for an open debate through Affinity Groups (ERGs), counting on members from all areas of the firm, including non-legal, with different level of seniorities, as main leaders of the initiatives, as follows:

  • Sponsor: Frederico Buosi (founding partner)
  • Gender AG: Gabriela Najjar (corporate partner); Bruna Gobbi (corporate partner) and Helena Vicentini (tax partner)
  • LGBT+ AG (Glow Brazil): Juliana Silveira (tax partner) and Samantha Santos (labour law paralegal)
  • Ethnics AG: André Avillés (civil senior associate); Alana Silva (marketing assistant) and Vanessa Oliveira (controllership analyst)
  • People with Disabilities AG : Ligia Fávero (civil senior associate); Isabella Rovesta (corporate associate) and Walter Oliveira (real estate jr associate)

The keystone targets set in increasing our hiring rates for minority ethnic groups and disabled persons and ensuring a safe space for all the LGBTQIAP+ and female team members. As a part of our strategy, VPBG has invested in developing and promoting its long term female staff as much as adopting an inclusive recruitment approach for women when seeking new talent in the market. Besides, in order to take its positioning and compromise with D&I in a place outside the firm, VPBG is involved in external projects, such as “Beequal”, a program to support families with children between 0 to 12 years old who has any kind of disability.

Also, together with Dentons, VPBG takes part into several D&I initiatives at global level, such as: WomenLead (a program created to improve women in legal network, as well as to provide mentorship for young female lawyers, counting with partners Bruna Gobbi and Gabriella Najjar as co-lieders in Brazil), DentonsGlow (LGBT+ lawyers affinity group, counting with the senior associate Juliana Silveira as the Representative for Latin America and the Caribbean Regions), Black Professional Network (Black lawyers affinity group), DentonsFusion (Asian lawyers affinity group) and NextTalent (a platform created to support its lawyers and other law firm professionals’ career goals, by focusing on the capabilities needed to be successful in the law firm of the future –  its sessions were crucial in bringing together the worldwide firm during the pandemic).

Pro Bono

Lead by our partner Rodrigo Vilardo Vella and our senior associate Fernando Henrique Lopes, VPBG helps institutions through pro bono work in relation to all legal aspects involved in their activities, such as corporate, tax, labour and IP.

VPBG assists Fundação Estudar and Turma do Jiló, which have highly qualified programs for social inclusion through education; Brasscom, a non-profit association whose purpose is to promote the information technology sector in Brazil; Renova BR, a non-profit association whose purpose is to promote the formation of political leadeprships in Brazil; Construide, a non profit association focused on building or repairing houses for needy people and families; among others such as Endeavor and União SP.

Among other relevant works are: (i) Assistance to Brasscom in relation to the legal aspects involved in the development of a digital platform to support the return to face-to-face work, which has helped several companies to follow a minimum retake protocol; (ii) Assistance to Renova BR in relation to definition of the tax treatment applicable to donations made to public hospitals engaged in the fight against COVID-19; and (iii) Assistance to Construide with regard to the tax deduction of the donations received.

Also, VPBG assisted Turma do Jiló, in relation to the legal aspects involved in a partnership with Instituto Serendipidade to develop the project “Escola de Impacto” which seeks to promote, in young people, competencies and skills in social responsibility. Our firm has been involved in reviewing the relevant agreements/documents and proposing adjustments in order to be compliant with the Brazilian tax legislation.

We are proud of our initiatives and our team hours dedicated to pro bono work, which has been growing every year.
