Mary Ann Frantz

I enjoy getting to know clients—their business strategies and goals, as well as their achievements and inspirations—and helping them prepare corporate documents that are clear, accurate, and professional. I provide clients with high quality, practical answers swiftly and efficiently, drawing on the experience I have acquired over four decades of assisting public and private companies and nonprofit corporations with their securities, business, and corporate governance issues.
