Founded in 1969 by Alfred H. Williams, A.H. Williams & Co began as a broker dealer. The firm specialized in fixed income sales, trading and investment banking focusing almost exclusively on tax free municipal bonds. His son Glenn began his investment industry career in 1979 in NYC, later moving to Philadelphia where he became a partner in AHW & Co in 1985 and developed expertise in institutional and proprietary trading. Glenn Williams served as Managing Director of the trading department and Senior Vice President up until and after Commerce Bank NA (now Toronto Dominion) acquired the AHW broker dealer.

In 2002, Glenn Williams left Commerce (TD) and began the process of converting his proprietary trading concepts and philosophy into a program that could be implemented in a registered investment advisory firm.

AH Williams & Co employs this expertise in institutional and proprietary trading to create an alternative way to invest in tax free municipal bonds. By using active management and margin accounts clients are able to participate in trades that traditional fixed income managers are not able to replicate without the sale of existing positions. AH Williams & Co separately managed account (SMA) programs are created for individual investors.
