WHAT OTHERS SAY
Algernon Sydney Sullivan Award
- Recipient of the Algernon Sydney Sullivan Award for Character and Commitment to Public Service in 2013
- One nominator wrote, "When one thinks of who Algernon Sydney Sullivan may have been as a young man, Ian Engdahl comes to mind. Not only do these two men share a love of the art of oratory and a passion for law and justice, but the philosophy of both revolves around making better the lives of others even before themselves."
