Our Story and Mission
Impact Infinity Law was founded in 2018 by Stéphanie Ernould, who had been practicing tax law since the beginning of her career.
She chose tax law for its unique position at the intersection of law and finance—complex, often opaque, and constantly evolving—requiring a deliberate stance in relation to a non-neutral party: the Government.
We practice exclusively in tax law, convinced that it allows every situation to be approached strategically—economically, personally, and financially.
