About Greg P.
Greg P. Curtis has spent more than three decades rooted in Wisconsin's legal community. He studied liberal arts at Lawrence University, earning his B.A. in 1986, and completed his law degree at the University of Wisconsin Law School in 1990. Those academic years set the stage for a steady local practice and a long-standing presence in regional professional circles.
After finishing law school in 1990, Curtis established a foothold in the Fox Valley area. He developed ties that would last through a career in both local and federal courts. He is admitted to practice in Wisconsin and in the United States District Court for the Eastern and Western Districts, which allows him to represent clients in a range of matters that cross state and federal lines.
Curtis became a partner and shareholder at Herrling Clark Law Office Ltd. in 2016. He works out of the firm's Appleton, Green Bay and Oshkosh offices, serving individuals and families across the region. His role at the firm includes supervising cases, advising clients on planning matters and representing them in court when federal jurisdiction applies.
Professional affiliations have been a steady feature of his career. He has been a member of the Fox Valley Estate Planning Council since 1990 and belongs to the Outagamie County Bar Association. Those memberships reflect an ongoing engagement with estate planning and local bar activities. He also coaches the Appleton West High School Mock Trial team, a role that keeps him connected to legal education at the community level and introduces young people to courtroom procedure and argument.
Outside the office, Curtis participates in community boosters and school activities. He has been involved with the Appleton West Terror Backers as a booster since 1990. That long-term local involvement mirrors his professional pattern: consistent, steady participation in organizations that intersect both civic and legal life.
Colleagues describe him as a practitioner who blends courtroom experience in federal districts with the everyday work of estate planning and client counseling. He remains based at Herrling Clark Law Office Ltd., where his practice centers on estate planning, probate matters and representation in state and federal courts. He currently practices at Herrling Clark Law Office Ltd., focusing on estate planning and related court work.
