Boston-based law firm Nutter McClennen & Fish LLP has expanded its national presence by opening offices in California and Hawaii through strategic combinations with trusts and estates boutiques. This expansion also includes the addition of attorneys in New York, marking the firm’s most significant growth in its 146-year history.
In California, Nutter has integrated the team from Hartog Baer, APC, a trusts and estates boutique. Effective August 1, 2025, the attorneys and staff of Hartog Baer have joined Nutter, enhancing the firm’s capabilities in private wealth and estate law on the West Coast. This move positions Nutter among the nation’s largest bi-coastal private wealth and estate law firms. ([nutter.com](https://www.nutter.com/?utm_source=openai))

Trainor, an experienced first-chair trial and appellate counsel, specializes in patent and life sciences litigation. Associate Jordana A.
