Sowell Management, a registered investment advisor based in Arkansas with $6.5 billion in assets under management and advisement, has introduced a new division called Cache River Private Wealth. The unit is designed to serve clients with a net worth of $5 million or more, a segment founder Bill Sowell describes as “high net worth plus.”
Cache River Private Wealth will offer what Sowell calls “family office lite” services, coordinating investment management, tax planning, estate planning, and multi-generational legacy and philanthropic initiatives. The goal is to address a common disconnect where clients’ attorneys, accountants, and financial advisors operate in silos, often with conflicting objectives.
“Clients tended to have their attorneys on one hand, whether those were attorneys for their businesses or for estate planning, and then they had their accountants, and then they had financial advisors,” Sowell said. “And a lot of times they really didn’t collaborate or coordinate to a large degree, and each were trying to accomplish certain things with a client that may or may not have been in concert with what the other part of the team was doing.”
According to Sowell Management’s latest Form ADV filing from March 2026, the firm employs approximately 100 advisor representatives and serves over 6,000 individual clients. Sowell estimates that 20% to 25% of the firm’s current client base meets the $5 million threshold for Cache River.
The new division will also drive a targeted recruiting effort. “For Cache River Private Wealth, we will specifically be recruiting advisors who have books that have at least 30 to 40 percent of their client base that fit that $5 million-plus bucket for clients,” Sowell said. “The reason that’s important is it’s a different conversation with clients that have net-worths of over $5 million versus clients that are smaller. Not that those are insignificant, but it is a different conversation.”
Cache River Private Wealth joins a growing list of family office service units launched by RIAs this year, including new practices from Wealthspire, Farther, and Summit Wealth Group. The trend reflects a broader push among advisory firms to offer more comprehensive, coordinated services to affluent clients.
Sowell Management remains majority-owned by Bill Sowell and his wife, Cindy, who serves as executive vice president. At $6.5 billion in assets, the firm is among the larger RIAs operating without outside investment. However, Sowell indicated that private equity investment could be a possibility in the future. “To say something like that’s down the road, it’s certainly possible,” he said. “At this point we’ve just focused on continuing to build and grow our firm. We’ve done a phenomenal job. We’ve got a great growth track record.”
Bill Sowell founded the RIA in 2001 and now serves as chief strategy officer after Daryl Seaton succeeded him as CEO in January. The firm’s latest ADV filing shows it manages assets for over 6,000 individual clients, with a significant portion now eligible for the new high-net-worth division.
