AmeriTrust Companies says it will merge with Argent Financial Group, an independent trust-based wealth management company; the deal should put Argent’s total client assets at $19 billion and its number of professionals at over 270 in the South.

Argent Financial has its headquarters in Ruston, Louisiana, and its wealth business includes oil and gas rights management. AmeriTrust is based in Tulsa, Oklahoma, and its financial planners have some $600 million in client assets.

“We are delighted to welcome AmeriTrust to the Argent family,” according to Argent Financial Kyle McDonald. “AmeriTrust’s fiduciary approach to wealth management meshes seamlessly with our business philosophy and, like Argent, AmeriTrust’s clients are accustomed to a high level of personal service. This is a big win for both of our companies and our clients.”

AmeriTrust Companies includes AmeriTrust Corporation, an Oklahoma trust company, and AmeriTrust Investment Advisors, an Oklahoma financial planning firm. AmeriTrust CEO Harvie Roe, who founded the company 21 years ago, will continue to manage AmeriTrust; Jerry Hudson, a fellow owner and director of AmeriTrust, and Roe will join the board of the merged trust company.

AmeriTrust and Heritage Trust Company of Oklahoma City, another member of Argent Financial, will operate under one Oklahoma trust charter, while continuing to do business as Heritage in Oklahoma City and AmeriTrust in Tulsa.

“This transaction is another step forward in our strategy to partner with other fiduciary companies and management teams who share our culture and business philosophy,” said Bond Payne, chairman of Heritage Trust, in statement.
