Areas of Practice

Nikolai J. Kleven


Born and raised in West Central Minnesota, I have had a passion for the outdoors since childhood. In my free time, you can find me with my wife and two young children at the lake, traveling, camping and hunting. My weekends are spent serving as a Judge Advocate in the Minnesota National Guard.  Protecting our Country’s environment and natural resources is a passion of mine, as well as protecting my client’s ability to use and enjoy them responsibly.

With a passion for upland bird hunting, I enjoy walking the prairie with my son and two German Shorthairs. In upland hunting, you need to put in the miles to find the birds. If you put in the time and energy, you will find what you are looking for. I take the same approach as an attorney; I’m not afraid to put in the time and effort to build long lasting relationships and work diligently for the best possible outcome for my clients.

The practice areas I am passionate about include:

  • Environmental Law & Litigation
  • Agricultural Law
  • Carbon Sequestration Law
  • Water Law
  • Endangered Species Act Law, Legislation, & Litigation
