From the Global Professional Breathwork Alliance directory and the International Breathwork Foundation member list. Both federations publish credentialed practitioners. The roster JSON merges them and groups practitioners by city for directory builds.

Each row captures a modalityMix object with counts per modality. The template renders the dominant modality as the headline and lists secondary modalities in a sidebar. This avoids forcing visitors to read every bio to figure out tradition lineage.

Yes. Wim Hof Method certified instructors are tracked separately because they're credentialed by a distinct organization. The wimHofCount field per row captures that population, and the template renders them as a separate section per city when present.

The inPersonRatio field captures the ratio of in-person to online sessions for the city's practitioners. Cities with predominantly online practitioners are flagged accordingly, which helps visitors choose practitioners who match their preferred session format.

Retreat-only practitioners are tagged with a retreatFocus flag. The template renders them in a separate section that highlights upcoming retreat dates when present, which helps visitors plan rather than expecting immediate session availability nearby.

Holotropic and intensive transformational breathwork are not risk-free practices. The template renders a safety callout per city that points to relevant credential bodies and contraindication resources. Credentialed practitioners are the headline for that reason.

Yes. The same JSON can drive an aggregate view that ranks cities by modality strength. SleekRank reads the same source across multiple page groups, so the same data feeds several views without duplicating any of the underlying records.

Both GPBA and IBF publish credential lists periodically. After each refresh, you merge new practitioners into the affected city rows and trigger a rebuild. Cities with new credentialed practitioners pick up updates and unchanged cities stay served from cache.
