The Firm

Two partners. One practice. Decades of counsel.

Halberstam & Crowe is a deliberate two-partner firm. We do not aspire to grow. We aspire to be retained by the same families a generation from now.

Since 1986

Forty years on Federal Street.

Halberstam & Crowe was founded in 1986 in a two-room office on Federal Street. The brief at the founding has not changed: to advise a small number of families on the documents that protect what they have built — for the people who come next.

In the decades since, we have stayed deliberately small: two partners, three associates, a paralegal, and a single fiduciary administrator. Every client knows the name of the attorney who will return their call.

The Partners

Two attorneys. Personally retained.

Marcus founded the firm in 1986 after a decade with a Boston Brahmin trusts-and-estates practice. He counsels first-generation founders and multi-generational families on the planning, governance, and quiet transfer of significant wealth.

Conviction

Three principles, written into every engagement letter.

I.

Patience

A plan written quickly is a plan written twice.

II.

Plain Language

Every clause must be readable by the person who has to live with it.

III.

Continuity

The attorney who drafts the document is the attorney who answers the call ten years later.
