An insurer-owned bank with $3 billion in assets is moving its Texas market main office into the lobby of an office tower in the Preston Center area.

Mutual of Omaha Bank, part of Mutual of Omaha Insurance Company, Omaha, Neb., will occupy 14,000 square feet at 5950 Sherry Lane, according to Robert Strong, the bank’s Texas market president.

The bank hopes to move into the space in December.
