Southern Minnesota Attorney, Solving Problems for Our Clients

Roko Law Attorney

Our Mankato attorney team provides exceptional representation based on our commitment to solve legal problems for our clients.  Our attorneys are:

  • Experienced: With more than 30 combined years of experience, two of our attorneys have worked as prosecutors — a great benefit for our criminal defense practice that most lawyers don’t have.
  • Esteemed: Our attorneys have received a 10/10 Avvo rating, BV rating, and have been listed as “Rising Stars” by Minnesota Super Lawyers and Minnesota Super Lawyer several times. The Rosengren, Kohlmeyer & Hagen Law Office has received many accolades indicative of their talent and commitment to high quality legal representation. Several of our attorneys speak nationally and internationally about criminal defense and family law.
  • Local: We know the prosecutors, judges, court administrators in nearly all of the Southern Minnesota courts. While we don’t expect special treatment as local lawyers, the familiarity we share with other attorneys and judges simply helps when we are advocating for our clients.
