Erika N. Simpson

Owner & Attorney

Erika has been in practice since 2013. She served as an Assistant District Attorney until founding Simpson Legal Co., PLLC in 2020.

Erika realized that many of the people she encountered professionally were confused and frustrated by the legal process. Most of the anxiety and frustration was caused by a lack of familiarity with the court system and communication barriers between attorneys and their clients. Once the process was explained in everyday language, it became easier for the client to navigate the process and make informed decisions with confidence. These experiences inspired the creation of Simpson Legal Co.

This particular background makes Erika uniquely suited for handling tough cases that often feature a highly emotional element. Erika has specific training in effective communication with children and teens, domestic violence, child abuse, sex abuse and elder abuse. These skills are helpful in conducting investigations for the court as a Guardian ad Litem. They are also helpful in approaching divorce and custody cases from a real world perspective–it is Erika’s goal to get you the best outcome available for your case and to keep you informed so you can tend to life while dealing with a legal issue.
