Arthur Orson Louissaint, Esq.

They call him the Lawyer of Wall Street—a figure so recognizable in the bustling Financial District that almost everyone, from business owners to longtime tenants, spots him the moment he appears. Part of that unmistakable presence lies in his meticulously detailed attire: he’s rarely seen without a three-piece suit, spats, walking stick, fedora, brooch, boutonniere, and the ever-present warm smile that sets him apart. Whether conferring with high-powered executives or pausing to greet a local resident, he radiates an unspoken warmth that draws people in.

​

His professional achievements speak for themselves: a restauranteur of 15 NYC restaurants, since 2021, he’s been counted among the Top 100 Trial Lawyers, and he has excelled in business law, civil & criminal litigation. As a Chief Legal Officer, trusted defense attorney, established restauranteur and business counselor, he guides an extensive roster of FiDi businesses and tenants through high-stakes negotiations and everyday challenges alike. Still, despite the weight of his responsibilities, he offers more than just legal counsel—he offers genuine humanity.

​

That spirit is most evident in his signature practice, once known as “Flower Fridays.” Originally a weekly gesture, it soon evolved into a near-daily tradition now called “Roses and Ink Day.” He can be found strolling through FiDi, handing out single roses accompanied by handwritten calligraphy notes, sealed with wax. The notes remind each recipient—whether they’re an acquaintance, a stranger, someone experiencing homelessness, or an unexpected passerby—of their inherent worth and the world’s appreciation for their existence. It’s this balance of legal mastery and heartfelt empathy, all while immaculately dressed, that compels people to take notice—and leaves them eager to learn more about the man behind the three-piece suit.
