Ted led the firm through unprecedented growth – from a $6 million, 40-person professional accounting firm to a $30 million, 190 person firm. Under his leadership, LaPorte also added three new offices and now has locations in Metairie, Baton Rouge, Covington, and Houma, Louisiana, and in Houston, Texas.

Six years after joining the firm, he left LaPorte to serve for five years as chief financial officer of a $200 million financial institution. During this time, Ted gained significant experience in areas such as mergers and acquisitions, initial public offerings, and strategic business plan development. He returned to LaPorte in 1991 as a member of the audit practice, where he focused on successfully building a strong financial institutions practice.
