Krikor Kouyoumdjian
In Memoriam

November 14, 1992 - December 27, 2025

January 12, 2026

The tragic loss of Krikor leaves us all bereft. I thank all of you who have reached out in the last two weeks.

As I transition to a new version of our firm, all of our current cases will be managed by me as time permits.

Krikor’s legacy lives on in the clients we served and the people who loved him.

Sincerely,
Jonathan Haderlein
