Lead with John Daniels

John began his legal career more than 40 years ago, concentrating on estate planning, business formation, trust administration, and real estate law. His work later expanded into executive leadership, first as in-house counsel and ultimately as Chief Executive Officer of St. Luke’s Health System, a major regional medical center based in Sioux City.


This path gives John a rare and valuable perspective. He understands how organizations operate, how families and leadership teams make important decisions, and how clear structure and thoughtful planning support sound, lasting outcomes.
