Greenberg Traurig, LLP has expanded its Finance Practice with the addition of Ethan R. Buttner as of counsel, based in the firm's New Jersey office in Florham Park. The global law firm announced the appointment on June 17, 2026. Buttner arrives from a senior institutional legal role, having served as Senior Vice President and Counsel in an asset-related capacity at his most recent organization.
What the Hire Adds to the New Jersey Team
Greenberg Traurig describes the move as a deliberate strengthening of its Finance Practice — language that signals headcount building rather than a straight replacement. Buttner's prior title as Senior Vice President and Counsel reflects executive-level legal work inside a financial organization, the kind of in-house background that tends to bring transactional familiarity and institutional perspective to a law firm practice group.
His placement as of counsel in Florham Park puts that experience directly in the New Jersey market.
Source Limitations
The firm's announcement does not name the institution where Buttner previously held his SVP role, nor does it detail the specific asset-related practice he supported there. No deal experience, client roster, or transaction volume figures were disclosed.
