About Willem & Margaretha
Gravett & Gravett
Our Family Protecting Yours
We are Willem and Margaretha Gravett, a husband-and-wife team of attorneys who founded Gravett & Gravett to fulfill our common vision of a law firm where our clients could truly be at the core of everything we do.
At Gravett & Gravett we are devoted exclusively to the legal issues that families face. We help them to protect the people, places, and things they cherish most, and to transfer their whole wealth – their financial, intellectual, and spiritual assets – to their loved ones.
As Personal Family Lawyers™, we forge life-long relationships with our clients, and through our total commitment to client care and service excellence, we strive to be our clients’ trusted advisors for life.
