Katherine Parmer

Katherine Parmer is an estate planning attorney with Oath who serves clients through the firm’s St. Louis and Chesterfield presence. She is licensed to practice throughout Missouri and Oklahoma and focuses on helping individuals and families create organized plans for their assets, wishes, and loved ones. Katherine works within an estate-planning model designed to make legal documents and long-term planning understandable, helping clients take practical steps toward greater certainty and protection.

Katherine earned her Juris Doctor from the University of Tulsa College of Law. She developed an early connection to estate planning by clerking with Oath throughout law school, gaining practical exposure to the firm’s planning process while completing her legal education. That combination of academic study and hands-on experience supports her ability to explain legal documents, identify planning priorities, and guide clients through decisions involving property, beneficiaries, incapacity planning, and future family needs.

Katherine’s work centers on estate planning rather than courtroom litigation. Through Oath, she helps clients consider trusts, wills, and related documents as part of a coordinated plan for managing assets and carrying out personal instructions. Her Missouri practice includes work connected to the firm’s Chesterfield office and St. Louis-area educational workshops, where estate-planning concepts are presented in a practical format designed to help families understand available planning tools and common legal concerns.

Katherine Parmer brings Missouri and Oklahoma licensure, law-school training, and continuing estate-planning experience to her client work. She focuses on creating clear legal plans that reflect a client’s priorities and reduce uncertainty for family members. Katherine’s background with Oath from law-school clerkship through attorney practice supports a consistent approach to planning, document preparation, and client education for people seeking a structured way to protect assets and prepare for future events.
