Hightower continues to build stakes in other firms and push ahead with an acquisition drive that has put it among some of the most vigorous M&A players in the North American market.

Chicago-based Hightower has taken a “strategic investment” in Grant Tani Barash & Altman, a preeminent Los Angeles-based business management firm serving high net worth and ultra-HNW clients. The move continues a run of such acquisitions of firms and partial stakes by Hightower.

As a result of the transaction, Grant Tani Barash & Altman will gain access to middle- and back-office resources and technology to increase the scale of their operations, Hightower said in a statement yesterday. 

The firm, which was founded in 1992, acts for a variety of individuals, families and businesses in the entertainment industry, as well as a variety of other firms.

"Grant Tani Barash & Altman, as business managers, are a compelling addition to the suite of tools Hightower already offers which include trust services, estate planning, and more; the collaborative possibilities are very exciting for us,” Scott Holsopple, chief growth officer at Hightower, said. 

Grant Tani Barash & Altman, whose principals are consistently included as top business managers in several industry publications, has about 80 employees based primarily in Los Angeles. 

As of December 31, 2021, Hightower's assets under administration were about $144.0 billion and its assets under management were $117.8 billion.
