We serve as lawyers for innovators and underdogs: people who are building from the ground up, solving hard problems, or challenging the status quo.
Some days that brings us to startups in garages. Other times it takes us to the Supreme Court. But everyday it fills us with purpose.
Not your typical firm
Founded in 2018 in Washington, D.C. as a startup onto itself, Schnapper-Casteras PLLC now operates in three cities and has clients across the United States. Our attorneys’ experiences in private practice, public interest law, and government service provide us a unique perspective on cutting-edge legal issues.
