Mr. Deinhart began his legal career at a law firm in the greater Cleveland, Ohio area in 1983. Seeking adventure and thinking they would return to Ohio after a couple of years, Mr. Deinhart and his wife moved to Guam in 1988 as a prosecutor where he worked for three years, handling all manner of criminal cases. After leaving the prosecutor's office, he remained on Guam and returned to a private, civil litigation practice. In 2001, Mr. Deinhart and his family moved to Arizona where he practiced civil litigation with a focus on real estate law. In 2009, he and his wife returned to Guam, finding that they missed the island, the ocean, and the people.
On returning to Guam, Mr. Deinhart joined Blair Sterling Johnson & Martinez. His practice is focused in the areas of insurance defense litigation, business litigation, insurance, securities and banking licensing and regulation, probate and estate work, collections, creditor bankruptcy matters and general litigation. Mr. Deinhart is also an experienced arbitrator.
Mr. Deinhart is the vice-chair to the Guam Bar Association Ethics Committee Investigatory Panel.
