MAI Capital Management Expands California Presence with Addition of OG Private Wealth

Acquisition brings approximately $551 million in AUM as MAI adds firm specializing in personalized investments and planning for entrepreneurs, business owners and affluent families across the state

CLEVELAND-August 18, 2026-MAI Capital Management ("MAI"), a registered investment advisor (RIA) focused on empowering clients to simplify, protect and grow their wealth, today announced the acquisition of OG Private Wealth, a fee-only RIA with offices in Chico and Hermosa Beach, California. OG Private Wealth manages approximately $551 million in assets under management (AUM) and serves more than 300 households nationwide. Terms of the transaction were not disclosed.

Founded by brothers Ryan O'Donnell, CFP®, and Mike O'Donnell, CFP®, following careers at leading wealth management firms including Merrill Lynch, OG Private Wealth was built on the belief that entrepreneurs, business owners and affluent families deserve a more personal, goal-focused way to manage their wealth. Its planning-first approachhelps clients simplify their financial lives by combining comprehensive investment management with holistic wealth planning that integrates cash flow oversight, estate planning, pre-sale planning and tax-efficient strategies in an all-in-one package.

Since its founding, OG Private Wealth has grown organically through strong client relationships, serving entrepreneurs, executives and affluent families across the country, with an especially established presence spanning Northern California, Los Angeles and Miami. The firm's footprint complements MAI's existing presence in each of these markets.

"Ryan, Mike and their team have built a business that's deeply rooted in trust. Their clients tend to have sophisticated wealth needs, and OG Private Wealth has made it their purpose to help clients navigate that complexity," said Rick Buoncore, Chairman & CEO, MAI Capital Management. "That commitment to long-term relationships and personalized planning is what we look for when acquiring firms[KA1] , and we're pleased to expand what's possible for their clients while preserving the culture that makes OG Private Wealth special."

Beyond a shared client service focus, Ryan and Mike O'Donnell's longstanding relationships with MAI's leadership team, deepened following MAI's acquisition of Evoke Advisors, reinforced their confidence that MAI was the right cultural and strategic fit for the firm's next chapter. The deal also supports the firm's vision to scale while adding the depth of resources and personal attention that its sophisticated clients require.

"We were looking to expand our capabilities, but we weren't willing to compromise the culture or client experience that has defined our firm" said Ryan O'Donnell, Market Leader, MAI Capital Management. "I've known the MAI and Evoke team for years and seeing how they built their businesses gave us confidence this was the right home. Joining MAI, one of the leading firms in the industry, gives us access to robust institutional investment capabilities, family office resources and specialized expertise that will help us serve our clients for years to come."

"After building OG Private Wealth for more than 15 years, we wanted a partner that could help us grow while allowing us to stay true to the principles we believe in," said Mike O'Donnell, Market Leader, MAI Capital Management. "The families and founders we work with have needs that extend well beyond a traditional investment portfolio, and they expect advice and services that rise to meet that complexity. With MAI behind us, we have the support to deliver on that commitment with more confidence than ever."

OG Private Wealth joined MAI effective August 14, 2026.
