By Michael P. Sampson February 17, 2026 Three and a half decades ago, Stu Webb sounded a note that sent hearts racing. People who heard him developed, harmonized, and amplified his first note. Creative, smart, driven, humble leaders, first in California, then well beyond, added depth and direction to a movement that became Collaborative Practice. The pulsing Collaborative Practice movement has steadily grown since the 1990s. As the music has evolved, it has inspired a flock that itself has inspired others to join the current – thousands worldwide, of all shapes and colors. They play not in a cacophony, but in a textured orchestra. They welcome new voices, players, variations, and ideas into Collaborative Practice. This article is part of Florida Collaborative Quarterly — Issue 001, a publication of the Florida Academy of Collaborative Professionals exploring the development and practice of Collaborative Law and interdisciplinary collaboration. The walls of the concert halls, connected in a global network, are flexible. They channel sound, energy, and creativity as the melodies fill the halls, testing their walls. Yet the guiding principles the first Collaborative players established support the music as it becomes more layered and expands to touch more people. From the first notes, to chords, to an anthem of hope, Collaborative Practice keeps swelling. The people whose needs Collaborative Practice and its practitioners serve drive them to keep practicing, playing, and improving. The Chord Makers: Why Not California…Why Not the US…Why Not the World? Among the first Collaborative Practice chord makers were Pauline Tesler, Peggy Thompson, Nancy Ross, Jennifer Jackson, and other Californian professionals. After they picked up Stu Webb’s signal, they began to develop Collaborative divorce in San Francisco and the Bay Area in the early 1990s. Not short on ambition or ideas, and prepared to persevere, they let their ideas develop into big ideas. If Stu Webb is the Bach of Collaborative Practice, Pauline Tesler is its Mozart. In her interview in 2007 with her colleague, Jennifer Jackson, a founding International Academy of Collaborative Professionals (IACP) board member and coeditor with Tesler of the voice of the IACP – its Collaborative Review – Jackson describes the early expansion of Collaborative Practice: So of course this lunch group that seemed to be growing into an organization needed a name, and our first thought was, San Francisco Bay Area Institute of Collaborative Professionals. But then we had a really radical thought: Why stop at the Bay Area? Why not – California! And so for a brief interlude, the name was going to be California Institute of Collaborative Professionals. But after about 45 seconds, it occurred to us: Why stop at California? Let’s incorporate as the American Institute of Collaborative Professionals – AICP! … I thought we were being unbelievable dreamers. But sure enough, AICP incorporated, and convened its first forum, in Oakland, in ‘99. Around 75 people attended, many of them from pretty far away, including Stu Webb, and that same year, we published the first issue of the Collaborative Review. Pauline H. Tesler, Making a Difference: Jennifer Jackson Helped Shape and Launch IACP, IACP Collaborative Review. Vol. 9, Issue 1 (Spring 2007) (emphasis added). Jamming in Chicago Like It’s 1999 Collaborative leaders met in Chicago in 1999. Jennifer Jackson describes the widening of the vision of Collaborative Practice from “American” to “International” after that meeting: The idea was, “There’s something happening out there and we want to find out what it is,” and people all over the U.S. and Canada were contacted who seemed to have any connection with Collaborative Practice, inviting them to get together in Chicago and talk. * * * As we talked in Chicago, a consensus emerged that a movement was beginning and that it needed an organizational clearinghouse and voice. We didn’t want micromanagement, but we wanted a central umbrella structure that could include everyone around the world who was becoming excited about Collaborative Practice. I stood up and said, “We’re from AICP. We already have a nonprofit corporation, our 501(c)3 status, and a journal. How about using that as our central umbrella structure! We will change our name and it can belong to all of us.” So before we were even a year old, our name changed again: we were now the InternationalAcademy of Collaborative Professionals. Pauline H.

The Music Takes Root The first note maker, Stu Webb, said: “…Collaborative Law is reinvented wherever it takes root.And that’s the way it should be.” IACP, Collaborative Review, Vol. 2, No. 3 (Fall 2001). Under the guidance of the chord makers, Collaborative Practice took root…then soared.

The IACP, Practice Groups, UCLA – Supporting Collaborative Practice with Form and Structure IACP: A Framework for a Coherent Whole From the Minnesota lawyer, California dreamers, and Canadian colleagues, the burgeoning Collaborative Practice network became the International Academy of Collaborative Professionals (IACP), a thriving, interconnected global community of legal, mental health, financial, and other collaborative professionals.What drives the IACP? The IACP states its mission: We unite and empower a global network of professionals who are dedicated to transforming conflict resolution using the principles of Collaborative Practice. In service of this mission, the IACP’s work includes: The IACP supports Collaborative Practice with a framework that has integrity without stifling new, creative sounds. Practice Groups: Composers and Players The IACP connects Collaborative practice groups throughout the world. Practice groups themselves connect Collaborative professionals with each other by city, region, state, or country. There are over 200 active practice groups in the United States, Canada, Europe, Australia, New Zealand, South America, Asia, and other countries. Colleagues in practice groups escape isolation in silos adversaries often find themselves in when working in other dispute resolution models. Members learn about each other. They form and build relationships. They see each other in action. Many first meet at general member meetings and become friends. Legal, mental
