But so do thousands of other American families who don't belong to the billionaire class. At their core, family offices are a means to invest, preserve and pass on fortunes-not to build them de novo. They're both a safety net and status symbol. "People are busy, and they want to know: 'How are we doing? Is there anything to worry about?"" says Mark Rogozinski, president of Family Office Services for Chicago-based Cresset Asset Management.
Family offices are taking off for many reasons, including increasing wealth and aggressive marketing to the ordinary rich. Baby Boomers and their elders also have concerns about passing on their accumulated wealth (in aggregate, some $84 trillion) and have a desire to involve younger generations in philanthropy. On the other side, the family office providers have access to new technology that can better monitor investment performance and share financial data, making it easier for them to expand. The final impetus is tax savings-the 2017 tax overhaul, coupled with a tax court ruling that year involving the Lender family (of bagel fame), mean that investment expenses which are no longer deductible on individual tax returns can often be written off at the family office level.
It's unclear how many single-family offices now operate in the U.S.-estimates range from 3,000 up to 7,000. But all agree that the number is growing. Deloitte conservatively estimates there will be 3,550 single-family offices in North America in 2025, up 61% from 2019. (For comparison, Forbes counted 880 billionaires in the U.S. and Canada in 2024.)
It still requires at least $100 million in investable assets (and preferably $250 million) for a single-family office to make sense, but those with as little as $25 million, or even $10 million, can find a spot with a multifamily operator if they're ready to pay for estate, tax and charitable planning and access to alternative investments like derivatives and venture capital.
A single-family office costs a minimum of $1 million annually (and usually more), but multifamily offices run from 0.5% to 2% of assets a year (generally, the bigger the portfolio, the lower the percentage). Sometimes there are transaction and performance fees as well. Concierge services, such as managing a client's homes and security and travel, may cost extra. The fee structure is often negotiable and bespoke, just like the services. Some multifamily offices charge a fixed fee per year, starting at $50,000 and ranging up to $1 million for full service.
More and more people want (and can afford) such white-glove treatment. The Federal Reserve's 2022 Survey of Consumer Finances found the richest 1% of Americans (that's 1.3 million households) had a minimum net worth of $11 million, while the top 0.1% (133,000 households) had a net worth of at least $46 million. The original multifamily offices were born when a single rich family invited in a handful of others to defray costs. Cresset, founded seven years ago in Chicago by two private-equity veterans to manage their own families' wealth, is one of a new breed of registered investment advisors expanding aggressively into the multifamily business. After merging in June with The Connable Office, a 130-year-old multifamily office, it's up to $60 billion in assets under management.
One new multifamily player, New York City's Beatrice Advisors, is the first owned by a Black woman. It was launched in June by Christina Lewis with assets from her own family and those of her rich friends. Her father, Forbes 400 member Reginald Lewis-a Baltimore-born, Harvardtrained deal lawyer-died in 1993 at 50 from an inoperable brain tumor. Christina was just 12 then, and describes her family as being "underadvised" at his death. Beatrice is investing heavily in technology, creating digital dashboards for its clients that display a family's whole net worth, including their investment portfolio, business assets and even intellectual property. The aim, Lewis says, is "transitioning our knowledge to the client over time, so that the client is in the driver's seat." In contrast to the Lewises, the Lipitz fa...
