About me

Originally from the west coast, I graduated from Westmont College in 1989.  While attending college in Santa Barbara, CA, I studied English Literature.  After graduation I chose to go to law school.


Having married an Iowan, extensive relocation negotiations ensued with the ultimate compromise being that I attended the University of Minnesota Law School.  I graduated Magna Cum Laude and Order of the Coif in 1992.


While still in law school, I began clerking at the Gilmore law firm in the spring of 1990.  After spending the following summer at a larger Minneapolis law firm, I returned to the Gilmore law firm where I worked as an insurance defense attorney from 1992 to 1996.  There, I tried a jury case and handled a variety of insurance related matters- my primary focus being worker's compensation defense.


In July of 1996, I came to work with Tom Mottaz- a position I have held ever since. Since that time I have tried over 300 worker's compensation cases.  I have also argued before the MN Worker's Compensation Court of Appeals on many occasions and I have argued before the MN Supreme Court once.  At present, 100% of my practice involves representation of injured workers under the MN Worker's Compensation Statute.

    David is one of the most formidable opponents I face in my workers' compensation defense practice. He is a consummate professional, skilled trial lawyer and passionate advocate for his clients. Quite simply, David is at the top of his field and a credit to his profession.
