Aggressively Representing Clients For Over 25 Years

Since 1989, I have been helping my clients resolve employment disputes in an innovative and cost-conscious manner. Motivated by my experience as an employee in the banking and insurance industry, I seek to reduce the complexity of workplace protocols and contracts that are at the root of many conflicts. It is for this reason that I work as an attorney: to design straightforward solutions for my clients.

My record of success in litigating claims associated with employment and labor law is well-known throughout Wisconsin. I have received large settlements on behalf of clients employed in sectors ranging from law enforcement to finance to social work.

Although I am proud of the multi-million dollar awards I have obtained for my clients, I receive the most gratification when an injustice is remedied to my client’s satisfaction. I consider legal advocacy to be my vocation.

Personalized Guidance For A Range Of Employment Matters

From our initial consultation to the presentation of your claims to the final negotiations on your behalf, I will collaborate with you to achieve the resolution you seek. While it’s often the case that clients of larger firms are shuffled between first-year associates and novice lawyers, I will serve as your legal adviser from the beginning to the end of the process.

In addition to providing responsive representation, I offer comprehensive legal services that address a variety of concerns for employees and employers, including:

  • Breach of contract conflicts
  • Harassment, retaliation and discrimination disputes
  • Employment, severance, noncompete and confidentiality agreements
  • Administration hearings and grievance arbitration
  • Company and municipal bylaws
  • Entity formation and compliance

I have the experience and resources to accept cases for clients employed in a variety of professions and business owners of small businesses.
