Los Angeles-based wealth management firm Signature Estate & Investment Advisors (SEIA) announced Thursday that it named industry veteran Matt Matrisian as President, effective April 28.
As President, Matrisian will replace Co-Founder Brian Holmes, who will continue to serve as CEO, the firm said.
Matrisian will work under Holmes and they will “co-lead SEIA’s national growth strategy, building on the firm’s record expansion through both strategic acquisitions and strong organic growth, while strengthening the infrastructure and resources to help advisors grow their businesses,” the firm said in a news release.
Most recently, Matrisian served as Head of Client Growth at AssetMark since October 2023 after serving as a Senior Vice President and Chief Channel Officer for nearly 14 years, according to his LinkedIn profile. Before AssetMark, Matrisian was with Raymond James Financial for more than 16 years, first as Divisional Manager and then as Vice President/Director of Practice Acquisitions.
His experience includes enterprise sales, business consulting and post-acquisition organizational design.
One of Matrisian’s main areas of focus at SEIA will be to enhance advisor engagement and expand services available to its advisors, the firm said. He will also “help drive the continued evolution of its estate, tax and financial planning approach, emphasizing consistency across the firm’s client engagements,” according to SEIA.
“As SEIA enters this next phase of strategic growth, Matt’s proven track record in M&A, channel expansion, scaling wealth management platforms and advisor technologies makes him the ideal leader to help us expand our national footprint,” Holmes said in the release.
Matrisian also “brings a deep understanding of what advisors need to grow and that expertise is critical for SEIA’s long-term vision,” Holmes said. “This addition represents a significant investment in our future as we continue building one of the nation’s leading wealth management firms.”
SEIA is “executing an aggressive national expansion strategy that prioritizes scale, support, and long-term advisor continuity,” Matrisian told WSR. “By the end of 2025, we expect to have more than 30 offices nationwide, a 20% increase in our physical footprint. Our short-term AUM target is $50 billion, with a longer-term goal of reaching $100 billion within the next five years.”
The firm’s national growth strategy is a “three-pronged approach,” Matrisian said. “We’re recruiting and developing new advisors, acquiring established practices, and also enabling existing advisors to relocate and establish our presence in new markets. This model has proven to be highly effective in allowing us to scale while maintaining our culture and client-first philosophy.”
Regarding the firm’s M&A plans, Matrisian told WSR, “We’re actively targeting firms that align with our core values and strategic goals. That includes those with strong AUM, geographic relevance to enhance our national referral coverage, unique capabilities like in-house CPAs or advanced planning, and advisor talent in regions where we don’t yet have a presence.”
Matrisian added, “Our vision is to have a physical presence in every major market where we already serve clients or see a clear opportunity to do so. That means establishing satellite offices and then scaling them into major hubs through strategic recruiting, advisor development, and acquisitions. In 2025, we’re prioritizing expansion into key markets such as Phoenix, Salt Lake City, Boston, Chicago, Northern California, South Florida, Houston, Dallas, Austin, San Antonio, New York City, the greater Northeast, Cleveland, and the broader Midwest. North Carolina is also on our radar as a growth market.”
But he pointed out, “Texas continues to be a core area of focus for us. In 2025, we’re actively expanding in Houston, Dallas, and Austin and we’re launching a new presence in San Antonio. We now have three advisors on the ground serving clients across these Texas markets, and we expect that number to grow significantly.”
On joining SEIA, Matrisian said in the news release, “Leveraging my experiences across M&A, technology, and advisor engagement to accelerate SEIA’s national expansion is incredibly exciting. I look forward to building on the firm’s momentum and creating scalable growth opportunities that will benefit both advisors and their clients.”
SEIA on Thursday also announced two promotions that it said were “designed to strengthen SEIA’s advisor services and growth initiatives.”
Eric Rosen was named Chief Growth and Strategy Officer, and, “to further strengthen SEIA’s operational backbone,” Howard Chen was named Chief Operating Officer.
Rosen was promoted from his previous role as Chief Compliance Officer, Holmes told WSR. “Eric has been an integral part of SEIA for over a decade, and during that time, his role naturally expanded beyond compliance to include overseeing strategic initiatives,” Holmes noted.
Chen had served as Vice President of Investment Services before his promotion, according to Holmes. “Each of these appointments strengthens our leadership bench and positions us for the next phase of national growth,” he said.
While supporting its growth strategy for the past year, SEIA says it added 58 advisors and home office employees while expanding its footprint with new offices across several states, including Arizona, California (San Francisco), Florida, Tennessee and Utah. The company now has 24 offices, it says.
“Today, SEIA has more than 60 advisors,” many of whom have been with the firm for more than 20 years, Holmes told WSR.
The new appointments follow more than 30% year-over-year assets under advisement (AUA) growth for the firm and its affiliates in 2024 to over $30 billion, it said.
In December, SEIA acquired Beverly Hills-based Beverly Investment Advisors, bringing its President and Founder, Canon Price, which had over $300 million in AUA. In August, SEIA acquired Cedar Brook, a $2 billion RIA based in Cleveland.
As of Dec. 31, SEIA and its affiliates collectively managed $25.5 billion in AUM and $30 billion in AUA, according to a company spokesperson.
SEIA has been backed by New York-based private equity firm Reverence Capital, since 2022.
