San Francisco–based Perigon Wealth Management has acquired Gitterman Wealth Management and Gitterman Asset Management, two New Jersey–based firms known for their focus on climate-aware investing. The transaction, which adds $1.3 billion in client assets, increases Perigon’s total assets under management to more than $10.6 billion.
Expanding ESG Leadership in Wealth Management
Gitterman, founded by Jeffrey Gitterman in 2000, has established itself as one of the early adopters of climate-conscious portfolio design. Through its advisory business and asset management platform, the firm developed a suite of climate-focused UMA models incorporating mutual funds, ETFs, and SMAs that have been adopted by advisor networks and wealth firms across the country.
Gitterman has also been recognized for its work with institutional retirement programs, serving participants in New Jersey’s Alternate Benefit Program (ABP) and Public Employee Retirement System (PERS). The firm’s deep integration of climate awareness into financial planning has positioned it as a leading name in sustainable wealth management.
Strategic Fit with Perigon
The acquisition underscores Perigon’s commitment to thoughtful expansion that aligns growth with values. Backed by Constellation Wealth Capital since early 2024, Perigon has been steadily building its platform but has remained selective in dealmaking. The Gitterman transaction represents its largest ESG-focused addition to date.
Following the deal, Jeffrey Gitterman and Eli Rauch will join Perigon as Managing Directors. In a statement, Perigon CEO Arthur Ambarik noted that both firms share a belief that “growth and principles go hand in hand.”
Gitterman added: “Partnering with Perigon ensures we can meet the wealth management needs of our clients’ families well into the future. Perigon’s strength in impact investing made the decision to join forces clear.”

The Bigger Picture: ESG Specialists Becoming Prime Targets
The deal highlights a broader trend in the wealth management industry: ESG-specialist firms are increasingly being targeted by larger platforms seeking to deepen their sustainability expertise and capture investor demand for climate-conscious solutions.
This acquisition is another marker that sustainable and climate-focused investing is evolving — it’s central to the competitive landscape of wealth management. With total ESG-related AUM expected to climb globally over the coming decade, transactions like this signal how market leaders are positioning for future growth.
Editor’s Note
I have followed Jeff Gitterman for more than three years and have consistently seen his commitment and passion for advancing climate resilience, adaptation, and responsible investing. His leadership has been instrumental in shaping the dialogue around sustainable finance and integrating climate awareness into mainstream wealth management.
ESG News extends our congratulations to Jeff, Eli, and the entire Gitterman team on this next chapter with Perigon. We look forward to seeing the continued impact their vision will bring to clients, the industry, and the global effort toward sustainable business and finance.
