John maintains a practice that is dominated by catastrophic and complex litigation in the State and Federal Courts. He focuses much of his time on insurance coverage disputes, bad faith defense, lawyer and insurance agent malpractice, business litigation, and catastrophic damages caused by all types of casualty risks, including transportation, construction, product liability, fires, and governmental liability, to name a few. He has also argued numerous appeals in the State and Federal appellate courts as counsel for a party and as amicus counsel for lawyer and trade associations. Through the years, he has been admitted pro hac vice in more than 20 jurisdictions, and is frequently hired by out-of-state firms to serve as local counsel in Indiana.

In the last 15 years, John has earned a reputation as one of Indiana's most sought after mediators. Because of the complexity of his litigation practice, John keeps the mediation to a manageable level, but he is frequently hired by judges and lawyers to mediate some of Indiana's largest and highest profile cases. He is also frequently named as an arbitrator in bodily injury, business dissolution, employment, and commercial disputes.

For many years, John has distinguished himself as a bar leader. He has been president of the state defense bar, and was named Defense Lawyer of the Year in 1991. He has also served on the Board of Directors of DRI, the largest national association of defense lawyers. In 2000, DRI named John its outstanding defense bar leader of the year. More recently, John has chaired DRI's national Judicial Task Force to explore and offer recommendations on how DRI can assist in maintaining a fair and impartial judiciary.

John has been repeatedly listed in state and local polls of attorneys as one of the top lawyers. In 2004 and 2005, he was named one of the "Top Ten Super Lawyers" in a poll of 14,000 Indiana attorneys.
