Rockefeller Capital Management has agreed to buy Illinois-based Whitnell & Co., a subsidiary of Associated Banc-Corp. Whitnell is Rockefeller’s second family office acquisition, following the addition of Silicon Valley-based Financial Clarity in 2019.

Whitnell provides financial planning, wealth management and generational wealth transfer services for affluent families across the Midwest. “The Midwest is a key region for our national expansion, as our footprint continues to geographically align with where Americans build businesses and create wealth. As we unite our businesses, we will be better positioned to serve our clients and offer robust solutions to solve for the complex challenges they may face.” says Rockefeller family office president Timothy O’Hara.

Wachtell, Lipton, Rosen & Katz is serving as legal advisor to Rockefeller, while HuschBlackwell is legal advisor to Associated.
