Dean Mailhes founded the Monroe office in February 1996.

Prior to that date Dean served as the Chief Investment Officer of Central Bank in Monroe. When Central Bank was purchased by a larger bank in 1996, Dean realized the change was not in the best interest of his clients (the purchasing bank was shortly sold to another bank, which was sold again). Dean joined Argent in large part because it gave him the ability to serve clients the way they should be served; local, fee based, and without the pressure to sell in house funds and products!

Vaughn Antley joined Dean Mailhes at the Monroe office in July of 1997. His primary responsibilities were the development and maintenance of client relationships within the Monroe area branch. At that time he was the assistant to Chief Investment Officer of Argent Financial Group in managing client portfolios.

From an initial staff of two, the Monroe Office has grown to nine employees ready to assist you with your financial needs.
