About the Firm
A small firm with the reach of a large one.
Founded in 1978 by Margaret Caldwell and James Mirren, our firm was built on a simple idea: that exceptional legal work requires exceptional attention. We remain deliberately small so that every matter receives the time, judgment, and seniority it deserves.
Our attorneys have argued before the highest courts in the country, negotiated transactions spanning four continents, and stood beside clients during the quietest and most consequential moments of their lives. We measure our success by outcomes — and by the trust our clients place in us, often across generations.
