Christopher C. Dinan has tried matters to civil juries throughout Maine and he has frequently argued cases before the Maine Supreme Judicial Court, including significant tort and insurance coverage matters. The Maine Superior Courts have selected him to serve as a discovery master in complex commercial litigation and appointed him to mediate sharply disputed civil litigation.

Mr. Dinan has served as a mediator or arbitrator in over two thousand cases, beginning in 1993. In this role he has helped resolve personal injury matters, insurance coverage cases, business disputes, construction disputes and intensely emotional matters involving alleged abuses of the priest-parishioner and therapist-patient relationships.

He is included in The Best Lawyers in America for his work in both Alternative Dispute Resolution and personal injury litigation. That publication has named him in recent years Portland's ADR attorney of the year, Portland’s arbitrator of the year, Portland's personal injury defense attorney of the year, and Portland's personal injury plaintiff's attorney of the year, reflecting his experience on all sides of litigation.
