About ZweigWhite

At ZweigWhite, we exist in order to help leaders in the architecture, engineering and environmental consulting industries achieve their business and personal goals. Since 1988, when the firm was founded by Mark Zweig (and later joined by Fred White), we have offered an ever-increasing and improving array of publications, services, and events designed to provide firm leaders with the tools they need to succeed. What began with a simple newsletter has grown over the last two decades to become a comprehensive suite of products and services, including newsletters, market research reports, seminars and executive education offerings, business conferences, and management consulting services covering virtually every aspect of business management.

Our dedicated team of writers and researchers are constantly interviewing business leaders across the U.S. and abroad to keep you informed on the latest news, trends, and economic outlook. Our survey staff are continually polling the industry to provide you with valuable benchmarking data on everything from financial performance to compensation levels. Our consulting staff has the advantage of working directly with hundreds of firms each year helping them to solve their most pressing business challenges. And every year we gather together business leaders and experts from around the world to our various industry conferences and educational events to learn and network.

Whether you purchase a publication, attend a seminar or conference, or engage us as consultants, you will be tapping into an unmatched reservoir of information and experience. Let us help YOU achieve YOUR goals.
