Creative Planning Inc. continued its buying spree with the acquisition of Miller Financial Management, a father-son registered investment advisor firm with about $150 million in assets under management.

The Muncie, Ind.-based firm, which is led by Chris Miller and his son Andrew Miller, is the third acquisition in four weeks and the ninth for the year for Creative Planning.

“We sought a firm that shared our vision for a client experience centered around financial planning and fiduciary values and we think Creative Planning shares our vision for that client experience,” Andrew Miller said in a statement.

Creative Planning CEO Peter Mallouk said he is excited to welcome the Millers and their team to the Creative Planning family. “They share our financial planning-led approach to investment management and match our culture and values. Together, we will be stronger as we build out our presence in Indiana,” he said.

Last week, the Overland Park, Kan.-based wealth manager acquired Cincinnati-based Lenox Wealth Management with about $600 million in AUM. And two weeks prior, it added another $600 million in AUM with the acquisition of Thun Financial Advisors of Madison, Wis.

Creative Planning manages over $50 billion in assets across all 50 states.
