New office will establish M+C’s presence in a major hub for private equity, M&A and technology, building on a series of significant senior partner additions nationwide

PALO ALTO, Calif., Nov. 9, 2026 /PRNewswire/ — Massumi + Consoli (“M+C”), a nationwide law firm recognized for its leading private equity and M&A practice, today announced plans to open a new office in the Silicon Valley with the addition of private equity/M&A partner Matt Stewart. The expansion bolsters M+C’s position in one of the country’s most prominent legal markets.

“The caliber of partners we’re attracting speaks to the strength of our platform and the opportunities ahead,” said Peter Massumi, Co-Founder of Massumi + Consoli. “Matt Stewart is the most recent example. He built a leading private equity practice. He had compelling opportunities to join some of the largest firms in the country. But he chose M+C because, in his words, this is the best platform to serve his clients. That’s a strong endorsement of what we’ve built so far and what we intend on building together.”

Stewart brings more than two decades of experience advising private equity funds and strategic acquirers. He is joining M+C from Weil, Gotshal & Manges, where he advised private equity funds such as Advent International, BlackRock, Khosla Ventures, Norwest Venture Partners, TPG and Trive Capital. He has been recognized as a “Notable Practitioner” for M&A in the U.S. by IFLR1000 and a “Rising Star” for Private Equity by Law360. He has also been named to The Daily Journal‘s 40 Under 40 list and recognized as an Emerging Leader by The M&A Advisor.

“Expanding our presence in the Silicon Valley is a significant step for our firm and a natural extension of our private equity and M&A practice,” said Anthony Consoli, Co-Founder of Massumi + Consoli. “We wanted to grow here with an exceptional lawyer who has the experience, relationships and reputation to help us build a meaningful presence. Matt brings all of that, and we’re excited about what we can build together.”

The Silicon Valley expansion follows a series of significant senior partner additions across M+C’s platform, the opening of its Orange County office, and the launch of ElevenHundred+, a management services organization that will build and operate the business, technology and operational infrastructure supporting the firm.

“Exceptional client outcomes is non-negotiable for me,” said Stewart. “My clients will be well-served at M+C. Further, the firm’s partnership with ElevenHundred+ addresses many of the issues destabilizing some of the larger law firms. It provides resources to grow the firm in a sustainable way while mitigating partner attrition. It’s a game-changer for our industry. It will deliver substantial value for clients. I’m thrilled to be a part of it.”
