Proactive employment practices help businesses avoid costly and time-consuming legal issues.

Experience 

Representative Matters

Mary and her clients have successfully managed challenging and potentially volatile workplace situations. When necessary, Mary works with clients to aggressively deal with situations that required court intervention. Mary works with clients throughout the upper Midwest and has represented them in litigation in Minnesota, Wisconsin, Iowa, Illinois, Michigan, Ohio, Missouri, Arkansas, California, Kentucky, and Pennsylvania.

In situations where employees brought lawsuits that could not be reasonably resolved, she and her clients have secured court dismissals and favorable jury verdicts:

  • Court dismissal of discrimination and retaliation claims brought by a student intern against a hospital and health care organization
  • Court dismissal of claims of discrimination based on gender and sexual orientation, disability, and retaliation asserted against a construction company
