Dr. Marcelo Vallejo Marsaioli
26 years with the same seriousness as our first case.
Marsaioli Advogados was founded in Santos in 1999. For more than 26 years, the firm has supported individuals and companies across Brazil from its home in the Baixada Santista, in the state of São Paulo.
Under the direction of Dr. Marcelo Vallejo Marsaioli, the firm brings together 19 professionals — attorneys, legal assistants and administrative staff — organized into 12 specialized practice areas.
We work across the entire life cycle of a matter, from prevention to outcome. Clients deal directly with the people working on their case: no queues, and no loss of context between departments.
Santos is home to Brazil's largest port, and our practice reflects it: from condominium and real estate matters to employer-side labor defense and the corporate needs of the port and logistics chain.
