SANDAPT is the San Diego Chapter of the non-profit Association for Psychological Type International (APTi), a volunteer-run 501(c)(3) that promotes learning and ethical use of psychological type. SANDAPT was established in 2003 by Patrick Kerwin and a small group of dedicated Type enthusiasts who wanted to create a local learning and networking forum for fellow fans.

What we do: Pre-pandemic, we presented six Type-related workshops each year on Saturday mornings, typically in January, March, April, June, September and November, with each workshop running 3 hours. During the pandemic, we are presenting virtual workshops via Zoom; most of these workshops are sponsored by other APTi chapters.

Our programs provide a fun forum for those wishing to brush up on their MBTI® (Myers-Briggs Type Indicator®) interpretation skills and stay current with Type knowledge, while learning new ways for using Type to enhance professional and personal interactions.

Why attend? To increase your experience of type differences live, face-to-face. By hearing directly how other types think, feel, and evaluate, you'll grasp type concepts more rapidly and deeply.

Membership: If you're interested in Type or the MBTI®, join SANDAPT and get free admission to all monthly workshops presented by various APTi chapters. You'll enjoy opportunities to "talk Type" with fellow enthusiasts and network around common interests.
