Katherine Mazaheri is a trial lawyer who regularly represents plaintiff employees in all areas of employment law, including litigation in state and federal courts, in mediation, before administrative agencies such as the Equal Employment Opportunity Commission (EEOC), Department of Labor (DOL) and Oklahoma Employment Security Commission (OESC).  She has successfully handled litigation involving claims of wrongful discharge, sexual harassment/assault, employment discrimination (based on race, age, gender, sexual stereotyping, pregnancy, national origin, and disability), retaliation, as well as disputes involving wage and hour matters, medical leave, confidentiality and non-compete agreements, employee handbook and company policy violations, and breaches of employment agreements. For over a decade, Mazaheri Law Firm has gained a powerful reputation for taking on cases that attack various social injustices leading to extensive recoveries for clients.

A portion of Katherine’s trial practice is devoted to assisting families in times of crisis. She assists clients with dissolution of marriage, custody and visitation, property division, and step-parent adoptions. Along with divorce, she assists couples in negotiation of pre-nuptial agreements and protection of assets.

As part of her employment practice, Katherine often trains and counsels employers on a broad range of matters affecting the workplace, including hiring, discipline, terminations, policies and procedures (including creation and auditing of employment handbooks), drug and alcohol testing, anti-discrimination and anti-harassment, employment contracts, severance agreements, and confidentiality agreements. More recently she has had the opportunity to educate tribal employees on sexual harassment and train 400+ employees in the workplace.  In addition, she was included as a speaker at Oklahoma Bar Association’s Labor and Employment Law Update for continuing education for attorneys in 2019 and for Oklahoma City University School of Law’s Alumni Association Cont. Ed. In 2020.

During the 2020 pandemic, she has assisted the public with online seminars including: Employment Law Q&A, Employment Guidance during the Coronavirus Pandemic, Employment Law Q&A: Back to Work Edition, and Illness in the Workplace: Employee Rights and Employer Duties.

In 2021, Katherine founded Maz Modern, her passion project to inspire professional inspiration for modern day working women with the purpose of empowering local women in the workforce. Katherine also launched a scholarship program with William & Lauren, called “Suited for Social Justice.” The scholarship gifted a custom suit and a $5,000 scholarship to a deserving new Oklahoma law school graduate who demonstrates a heart for social justice and pledges to make a difference in their community though their degree.
