The Armonk, New York-based retirement plan consulting firm has $3.8 billion in assets under advisement.

One Digital Investment Advisors, a subsidiary of OneDigital, an insurance brokerage and HR consulting firm, announced Thursday that it had acquired StoneStreet Equity, a retirement plan consulting and wealth management firm in Armonk, New York, with $3.8 billion in assets under advisement.

StoneStreet was founded by Robert A. Goldstein and is currently led by principal and chief investment officer Spencer Goldstein and principal and managing director Heidi Sidley.

“Our father, Bob Goldstein, a pioneer in the retirement plan industry, taught us first and foremost to treat our clients like family,” Sidley said in a statement. “His leadership, expertise, and values have driven our clients’ success in unmeasurable ways.”

Vincent Morris, president of retirement and wealth at OneDigital, noted StoneStreet’s expertise in defined-benefit plans as well as 401(k)s.

“The StoneStreet team provides a full suite of defined-benefit plan asset management, de-risking, and pension risk transfer services to help clients manage their asset-to-liability ratio and reduce their pension liabilities over time,” Morris said in the statement. “We continue to build out a best-in-class consulting platform for our clients to access a full range of business consulting strategies.”

OneDigital serves more than 1 million plan participants.
