Cerity Partners absorbs Cornerstone Capital and Echo Wealth Management, adding $1.7 billion and a Minneapolis foothold

Cerity Partners said Thursday it is absorbing Palo Alto's Cornerstone Capital and Minneapolis-area Echo Wealth Management, a pair that adds roughly $1.7 billion in combined assets under management to a platform already reporting more than $206 billion. Against that base, the new assets amount to about eight-tenths of one percent — small enough that the transaction turns on Echo's executive-compensation practice and a Minneapolis foothold, not scale. Cornerstone contributes roughly $1.4 billion of the total, Echo about $337 million, and both practices will take the Cerity Partners name.

Cornerstone dates to 1978 and works with high-net-worth individuals and families as well as charitable foundations and endowments, combining investment management, financial planning and estate and tax coordination. Echo, the newer and smaller piece, was founded in 2015 by advisor and planner Echo Huang, and it has grown from tax planning into helping corporate executives handle equity compensation and other complex financial decisions. Minneapolis is, in the words of Cerity partner and head of partner development Claire O'Keefe, "an important growth market for our firm," and Echo supplies Cerity's first foothold there.

Echo's client work makes it more than the smaller half of the deal, because Cerity bought into the same specialty once already this year. In July the firm agreed to merge with Portland-based Cordant Wealth Partners, a roughly $371 million practice focused on technology employees managing restricted stock units, employee stock purchase plans and deferred compensation. Echo works that terrain from a different city, which suggests Cerity is treating executive equity compensation as a product line it intends to keep buying rather than a one-off practice it happened to like. On that read, Cordant is the template: keep the specialty, keep the client-facing team, and bolt the practice onto a platform whose tax, estate and planning infrastructure is deeper than a $371 million firm can build alone. Huang framed the move in those terms, saying her clients will "continue working with the same team they know and trust" while gaining access to Cerity's broader resources.

Cornerstone and Echo are the fourth and fifth firms Cerity has been tied to this year, after Austin Private Wealth in Texas and SOL Capital Management in Maryland at the start of 2026, and Cordant in July. That pace reads as a buyer with a deal team and a process rather than a firm shopping opportunistically, and it stands out in a market whose aggregate numbers have wobbled: as this publication reported in September, deal counts fell 19% in a week that funded buyers nonetheless carried.

Cerity's September 26 regulatory filing put the firm at $161.7 billion in regulatory assets across 26,230 accounts and 1,529 employees. That measure and the advertised figure are different, and public AUM can legitimately exceed what a firm files, but the gap here runs to at least $44 billion — the kind of discrepancy a buyer's diligence file flags early, and one worth watching as the announced deals close and the next filing lands.

That filing puts the average account at roughly $6.2 million, the arithmetic behind O'Keefe's characterization of what just changed hands: "Cornerstone Capital has spent nearly 50 years building the kind of deep, multigenerational client trust that can't be manufactured, only earned." Brad Dinsmore, a partner at Cornerstone, supplied the other side of the trade — the firm wanted a buyer that would preserve its approach while broadening what it could offer clients, and in Cerity it found tax, estate and other resources it could not offer on its own. That is a firm concluding the build costs more than the buy, the calculation this desk would argue moves more advisory deals than price does.

Minneapolis is the smaller half of the deal and the more interesting one strategically, because Cerity carries no Twin Cities presence and Echo's $337 million buys a local brand, a referral network and a named team with roughly a decade of history — a shorter route into a market than hiring it advisor by advisor. O'Keefe called the Twin Cities a priority market, and whether that priority shows up as a second acquisition there or as recruiting into the office Echo brings is where the acquirer's integration capacity gets tested.

Both firms will take the Cerity name. That is the structure of an operating platform rather than a holding company of local brands, and it puts a partnership founded in 1978 under a firm with 1,529 employees and 26,230 accounts on its regulatory filing. Cornerstone's partners chose a platform over standing alone, and the partner-level language about preserving the approach is what every seller says and no seller can guarantee. How many firms of Cornerstone's vintage are weighing the same choice is not stated, and Cerity's partner-development bench, which O'Keefe leads, exists to keep that pipeline full. The fourth-quarter deal count is where the next answer will show up.
