An exclusive, immersive, group experience combining process group dynamics, classroom learning, and 1:1 coaching for an in-depth Enneagram experience unlike anything you’ve ever been a part of before!
A monthly immersion + live clinic for serious students and practitioners
Step into a living, breathing laboratory of transformation. The Enneagram Mastery Circle is a high-level, intimate container for people who care about rigor, clarity, and soul-level development. Whether you’re a practitioner, teacher, or devoted student, this circle is where we refine perception, test ideas against lived reality, and translate insight into practice.
Each live two-hour session is guided by EA founders Sterlin Mosley, PhD, and Aaron Addonizio, MHR. We blend concise teaching with live demonstrations, real cases, and open Q&A/typing help so you can bring what’s actually happening in your work and life into the room.
More than a class, Mastery Circle is a resonant community. Complexity is welcomed. Nuance is expected. Growth is witnessed. You leave each month with sharpened skills, grounded language, and the support of a cohort committed to evolution.
You’re in the right place if you want the Enneagram held with reverence, rigor, and warmth—and you’re ready to use it well.
The Enneagram Mastery Circle is:
Hybrid learning + live clinic. Short teaching segments, casework, and 1:1 coaching inside a group setting.
Real practice, real time. Bring questions, client vignettes, confusing typings, family/partner dynamics—let’s read the structure together.
Clean, usable language. We’ll model how to name patterns precisely without shaming, and how to intervene cleanly.
Community that sharpens you. Group mirroring heals the social field and refines perception, even for very experienced folks.
Integration over information. Everything we teach is meant to live in your sessions, teams, and relationships the same day.

Sterlin Mosley Ph.D
Aaron Addonizio M.H.R, M.P.A.
Hi, we’re Sterlin Mosley Ph.D and Aaron Addonizio M.H.R, M.P.A.
We’ve been studying the Enneagram for 24 years. First attending Enneagram courses from Tom Condon, Russ Hudson, Helen Palmer, David Daniels, and others, we regularly attended Enneagram conferences where in 2007 we met Katherine Fauvre. Sterlin became Katherine’s protégé around the same time and began doing bi-weekly one-on-one coaching to further his understanding of both the Enneagram and his own processes.
In our Master’s in Counseling program, Sterlin and Aaron researched the Enneagram personality types, and psychopathology and diagnosis, which took us deeper into the work of Claudio Naranjo.
From there, we started our first Enneagram business in 2008 where we delivered trainings to counselors and psychotherapists for CEU credits and then began delivering online trainings and classes the same year.
In 2014, we both became certified teachers and coaches with Katherine Fauvre of Katherine Fauvre Consulting. Sterlin completed his PhD in Communication from the University of Oklahoma in 2014 where he conducted several studies on the Enneagram, self-presentation, and intrapersonal communication.
Until 2021, Aaron worked for several years as Katherine Fauvre’s office manager. In addition to Aaron’s professional counseling education, she received a Master’s in Public Administration in Nonprofit Management.
In addition to Empathy Architects, which we founded in 2019, Sterlin is an Assistant Professor at The University of Oklahoma where he teaches various courses in the Human Relations and Women’s and Gender Studies departments. Sterlin teaches an undergraduate level course on Personality (which is essentially a semester-long course on the Enneagram and other systems such as MBTI, the Big Five, Jungian Archetypes, multiple intelligences, microexpressions, etc). Together, we have delivered countless trainings, workshops and courses.
We both share a love of systems and have a particular aptitude for synthesizing those systems in order to foster greater self and other awareness with the aim of creating greater compassion and empathy for everyone.
