Portia C. Kayser


With over 10 years of litigation experience and 18 years of business consulting experience, Portia brings a depth of knowledge in the areas of construction litigation, governmental liability and civil rights, appellate law, and alternative dispute resolution.  She represents both small and large businesses, including architects, engineers, contractors, and owners in complex construction law cases, involving defense of claims of catastrophic personal injuries occurring at construction sites, construction defect claims on commercial and residential projects, mold infestation, EIFS failure, professional design liability and OSHA administrative matters. Portia also represents city and county governments, and other public entities in a wide range of legal matters, including law enforcement liability, civil rights, municipal liability, open records and meetings, and zoning and land use issues.

Portia is a certified mediator with a passion for helping parties find creative resolutions to their conflicts. She is a strong advocate of alternative dispute resolution and putting the power to resolve cases in the hands of the parties rather than having to accept a decision made by strangers in a court of law.

Portia is also an adjunct professor at St. Louis University School of Law. She has been recognized by the Missouri Lawyers Weekly as a Women’s Justice Award Winner, recognized in Best Lawyers and St. Louis Top Lawyers in the area of municipal litigation, and is a frequent speaker on topics ranging from construction contracts to appellate advocacy.

While in law school, she served as a judicial intern to the Honorable Judge E. Richard Webber of the United States District Court for the Eastern District of Missouri. Prior to joining Practus, Portia was Managing Partner of Fisher Patterson Sayler & Smith’s St. Louis, Missouri office.

When she’s not working, Portia enjoys spending time with her 5 kids and 4 dogs. She also loves cooking, baking, and traveling.
