Arroyo Castelazo y Asociados, S.C., was created initially in 1980, by lawyers who worked during several years as attorneys in the prestigious worldwide law firm Santamarina y Steta, one of the largest and most well known law firms in Mexico from the fifties to the seventies. Having noticed that many clients required a more personal service, dedicated and tailored to their special needs, Arroyo Catelazo decided to create with other partners a small boutique law firm to provide exclusive and individualized services according their clients’ needs, specialized in Corporate and Labor Law counseling and litigation. In 1975 the firm changed its name to Arroyo Castelazo y Asociados, S.C.
