About Weiss


At its best, accounting is a truly entrepreneurial profession. Top practitioners develop their own individual styles and specialties, and build their practices on long-term client relationships based on mutual trust and loyalty. They take deep pride in what they do, and relish the opportunity to work with others who feel the same.
