“Sterlin and Aaron are the sharpest enneagram authorities in the community… Unlike the others, Sterlin and Aaron take the Enneagram very seriously and operate like a surgeon's knife - able to precisely dissect the enneagram and shine light on the shadowy aspects on the human ego so that the truth behind the types are accurately revealed amidst the ambiguity of Enneagram imperfection. The differences between each type, Trifix and instinct can be very subtle, but if you are looking to take your enneagram knowledge from being 'just good enough' to perfection, I would highly recommend taking notes and studying their material carefully.”

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.
