Step into a living, breathing laboratory of transformation. The Enneagram Mastery Circle is a sacred, high-level container for those ready to explore the deeper, more nuanced dimensions of the Enneagram. Whether you’re a practitioner, a teacher, or someone who feels the pull of this system’s truth, this intimate circle is a space to refine your understanding and connect with others who care about depth, clarity, and soul-level development.

Each live two-hour session is guided by EA founders Sterlin Mosley, PhD, and Aaron Addonizio, M.H.R. Together, we dive into advanced typing work, live demonstrations, and real-time conversations on the subtle art of transformation using the Enneagram.

More than just a class, the Mastery Circle is a space for resonant community, where insight is shared, complexity is welcomed, and growth is witnessed. You’ll walk away each month with sharpened skills, embodied wisdom, and the support of a collective committed to the path of evolution.

You're in the right place if you’re craving a space where the Enneagram is held with reverence, rigor, and warmth.

The Enneagram Mastery Circle is…


☞ A hybrid approach combining process group dynamics, classroom learning, and 1:1 coaching to create a comprehensive growth experience.

☞ Experiential group work with real-time interaction that deepens self-awareness and catalyzes transformation.

☞ The collective learning environment offers group feedback and mirroring, which can deeply heal the social instinct, even if it's not your lead instinct. Seeing yourself through others' perspectives fosters mutual support and authentic growth.

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.
