About me

Erin received her law degree from the University of Wyoming in 2001.  Prior to that, Erin worked as a nurse and was head of the workers' compensation department for a large company in Colorado.

Since becoming an attorney, Erin has practiced in criminal law, family law and workers' compensation.  Erin was a deputy county attorney in Gillette, Campbell County, Wyoming before opening Plains Law Offices, LLP with her husband, Kenneth DeCock, in 2004.  Erin was appointed to the Wyoming Legislature in 2005, and served in that capacity for five years.


Erin now practices primarily in workers' compensation law, and family law.  Erin's understanding of the legal and medical fields helps her achieve the best results for her medical and workers' compensation clients.
