Attorney at Law

about David D. Knoff


I grew up in Willmar, Minnesota, graduating from High School in 1989. The combination of lakes and agriculture in the area instilled a love of the outdoors and the desire to live and work in an area where I can know and trust the people I encounter every day.

I graduated from South Dakota State University with an undergraduate degree in economics. I received my law degree from the University of South Dakota and have been with this same law firm ever since graduation.


Like many smaller-community lawyers, I have had the opportunity to practice in many different areas. I have worked with everything from small businesses just getting started to personal injury litigation. Over the last several years I have concentrated on estate planning (wills and trusts) probate and real estate matters. I am also often involved in trust and estate litigation on a regular basis. I have a particular interest in farming operations and enjoy working with farm families in planning succession while being fair to all of their children. I have also counseled many families who are dealing with an elderly parent who will need nursing home care in the future.

I also perform mediation in an attempt to resolve disputes before they get out of control—both financially and emotionally. I primarily deal with family disputes, including custody and divorce, however I have done personal injury mediation as well.


I am a licensed attorney in both South Dakota and Nebraska. I am admitted to both state and federal court in both states, as well as the United States Supreme Court. I am on the Elder Law committee of the South Dakota Bar Association.


No stranger to community involvement, I have been the Mayor of Yankton (2010-2012) and am currently on the City Commission. I am on numerous committees within Yankton and have present and prior involvement in the Yankton County Bar Association and the American Bar Association’s Young Lawyers Division.
