Who We Are

John R. Dietrick

John R. DietrickJohn R. DietrickJohn Dietrick has been actively involved in the practice of law for almost 40 years, is licensed in both Kansas and Louisiana, and is a member of the Kansas Bar Association, the Louisiana Bar Association, the American Bar Association, and the United States Supreme Court Bar Association.

He enjoys traveling and found a desire to explore the world after serving two (2) tours of duty as a Vietnam helicopter pilot. After receiving his Juris Doctorate, he spent three (3) years, as an Associate Attorney in New Orleans, LA. In New Orleans, he learned to understand the French Civil Code, appreciate the classic bowl of gumbo, respect the cayenne pepper, and that battling the tourist hordes for a Café Du Monde beignet was worth it.

John also has a deep and profound understanding of crafting the perfect martini and tasting a full-bodied glass of cabernet!
