Mark Sherman

Mark’s practice focuses on defending Oregon and Washington employers in state and federal courts. These cases run the gamut from denial of due process and deprivation of property and liberty interests to claims brought under Title VII and analogous Oregon and Washington state law for employment discrimination, harassment, and whistleblower retaliation.

In addition to defending private employers, Mark has extensive experience defending municipalities and special districts against all types of tort claims, including Section 1983 claims for excessive force and wrongful arrest, First Amendment claims, Title IX claims, and public accommodation claims brought under the Americans with Disabilities Act.

Mark is adept at winning “trials on paper,” writing motions to dismiss and summary judgment motions that have resulted in the dismissal of numerous state and federal court cases prior to trial. He was recognized as a Rising Star by Oregon Super Lawyers Magazine in 2012 and 2014 – 2018.

Representative Cases:

Flores-Haro v. City of Hillsboro and Washington County et al. – won Ninth Circuit appeal reversing district court’s decision denying qualified immunity for individual police officers based on allegedly excessive force.
