Brown Advisory is gearing up to more than double its New York footprint, packing its bags for 520 Madison Avenue, the Tishman Speyer tower near the Plaza District. The relocation comes as the firm elevates Danielle Barrett to head of its New York office, a move paired with plans to boost client and advisory services across the city. Brown expects to complete the relocation by the end of the year as it builds out additional space for both advisors and clients.
New Leader For A Growing Team
The firm announced on June 25 that Danielle Barrett, a client advisor and partner who joined Brown Advisory in 2017, will lead the expanding New York office. In a press release, the company said 83 colleagues are currently based in New York and that it managed approximately $188.9 billion in client assets as of May 31, 2026. Barrett will keep advising clients while taking on responsibility for the office’s growth and client engagement strategy. Brown Advisory provided these details in its announcement.
Where The New Office Will Be
Lease filings and trade coverage show Brown Advisory has signed a 15-year deal for about 34,748 square feet at Tishman Speyer’s 520 Madison Avenue, taking the full 27th floor and part of the 26th floor. That jump will more than double its current Midtown footprint, which sits at roughly 16,000 square feet. As reported by Commercial Observer, the relocation is slated for the fourth quarter of 2026 and was brokered with JLL representing Brown Advisory. The outlet notes that 520 Madison has been a sought-after Plaza District address, especially among finance and investment tenants.
Trophy Space Still In Demand
Tishman Speyer has cast 520 Madison as a trophy Plaza District tower, and leasing activity around the property has pushed availability down. The landlord has said the building is nearly fully leased, and it has framed Brown Advisory’s commitment as another vote of confidence in Midtown’s high-end office stock. Those landlord comments and the leasing backdrop were highlighted by CityBiz.
What It Means For Midtown
Industry data indicate that Midtown and the Plaza District have tightened in recent quarters as demand for trophy and Class A space outpaces supply. That pattern helps explain why firms like Brown Advisory are willing to ink longer-term deals in marquee buildings. Market summaries from broker reports and neighborhood research show rising asking rents and lower availability in Midtown during early 2026. Metro Manhattan notes this tightening in its Plaza District market overview.
“Danielle brings a combination of technical expertise, sound judgment, and genuine care for clients and colleagues,” Charlie Constable said in the firm’s announcement. The release frames Barrett’s promotion and the move to 520 Madison as part of a deliberate push to expand Brown Advisory’s New York presence and deepen its client service capabilities, a narrative also covered by the Baltimore Business Journal.
