Zachary T. Flood

If you have been injured, hurt on the job, or facing criminal charges, call me today.

I grew up on an acreage just outside of small town, De Smet, South Dakota with my parents and three younger sisters. This is where my family instilled small town values, work ethic, and a drive to seek justice.

After graduating high school, I attended the University of South Dakota (Go Yotes!) in Vermillion majoring in Business Economics. I decided to stick to my South Dakota roots and stay at USD for law school. While in law school I was the President of the Trial Team where I spent time traveling the nation competing against the nation’s future top litigators.

After law school and prior to becoming a full-time litigator, I worked as a law clerk for the First Judicial Circuit based out of Mitchell, South Dakota. My wife, Brittni, and I, along with our two girls have since made Mitchell our home. I am an active member of the South Dakota Trial Lawyer’s Association and was recently recognized as a Top 10 Personal Injury Attorney for 2019 by the American Institute of Personal Injury Attorneys as well as a Top 40 under 40 Trial Attorney.

My experiences in capital cases and multiple jury trials coupled with the insight, acumen, and experience gained working with the very Judges who will decide your case cannot be overlooked. I was raised with the same hard working, Midwest values I bring to all my cases in and out of the courtroom. You can trust that I will invest the time, effort, and skill into ensuring you obtain the best possible outcome.

Give me a call today. Let’s demand your Justice together.
