In November 1980, Tom Sponsel, a manager with Arthur Andersen & Co., joined the firm and became a shareholder in 1983. In July 1987, the firm name was changed to Greenwalt Sponsel & Co., Inc.

To deliver on this, we are organized and operate through four separate industry teams and five separate functional expertise levels. We recognize that it is through the individual actions of our employees that our firm is the premier client service organization throughout Indiana.
