Over the years, Mr. Nelson has advised a wide range of clients including state & local governments, universities, utilities, and transportation concerns in issuing more than $6 billion in project financing.


He is also experienced in solving structural deficits within operating budgets. During the late 1990s Mr. Nelson served as lead advisor to the then financially distressed District of Columbia. He and his team were instrumental in closing a $350 million budget deficit, regaining access to the bond market and restoring the Districts autonomy from the U.S. Congress.

While Mr. Nelson leads most of our efforts on a day-to-day basis, there are four others who are part of the original founding group whose intellect, support, and spirit are frequently tapped for the benefit of our clients - though they are not employed by the firm. "We each excelled in a different speciality area, but found that when we worked together on a problem, something creative and good resulted."
