If you're looking for a practitioner trained in the Upledger approach to craniosacral therapy, the IAHP (International Association of Healthcare Practitioners) directory is the main place to start. It's a public database of practitioners trained through the Upledger Institute and its educational arm, IAHE (International Alliance of Healthcare Educators).
The directory uses a system of credential labels that can be confusing at first. Some practitioners have plain 'Network Member' status. Others are 'Certified Therapists.' Some are listed as teachers or teaching assistants. Knowing what the labels mean helps you get more from the directory and a clearer sense of who you're considering.
The core credential
The basic entry into the IAHP directory is Network Member status. It indicates affiliation with the IAHP and likely attendance at Upledger Institute training, but says nothing about completion or examination. Many practitioners listed at this level have attended workshops without going through formal certification.
The more substantive credential is Certified Therapist, sometimes abbreviated CT. This means the practitioner has completed the core Upledger CST curriculum — typically starting with CST I and CST II and continuing through more advanced modules — and passed a practical and written exam. The exam is what makes this meaningful: there's been an external check on competency, not just attendance. That's a real distinction from completing a series of workshops with no formal evaluation.
Within Certified Therapist, you'll see further distinctions. CST-T means a therapist who has reached Certified Therapist level. CST-D is the Diplomate, which requires more advanced coursework and assessment beyond the basic certification. Diplomate status is fairly rare and indicates deep engagement with the Upledger curriculum specifically.
IAHE teachers and teaching assistants
IAHE Teacher status means the practitioner is authorised to teach Upledger Institute courses. That's a separate vetting process from clinical certification, and not every Certified Therapist becomes a teacher. IAHE Teachers go through additional preparation and are credentialed to run the formal curriculum — CST I, CST II, and the advanced courses. Someone with IAHE Teacher status has a long-standing, formal relationship with the Upledger training system.
Teaching Assistants help instructors during courses but don't run the curriculum on their own. It's often a step toward full IAHE Teacher status. A Teaching Assistant listing tells you the person has experience in the teaching environment but at a different level of formal authorisation.
For patients, teacher and teaching assistant status is less directly relevant than Certified Therapist status. But it's a useful signal — it tells you the person has an ongoing professional relationship with the training organisation that goes beyond having taken a course.
Using the directory practically
The IAHP directory lets you search by location, credential type, and specialty. When using it to find a practitioner, filter for Certified Therapist status at minimum — especially if you want someone for a specific condition. Network Member listings are worth checking when local options are thin, but they tell you less about completed training.
What the directory can't always tell you is how recently someone trained or how active they currently are in CST. Some listed practitioners completed Upledger training years ago and now work mostly in another modality. A short conversation or a look at their website usually clarifies their current focus.
It's also worth remembering that the IAHP directory covers the Upledger approach specifically. Biodynamic craniosacral therapy (BCST) has a separate training lineage and different professional associations — BCTA/NA, CSTA, PACT. Practitioners from the biodynamic tradition won't necessarily appear in the IAHP directory, and those in the IAHP directory may not have biodynamic training. Both traditions work with the craniosacral system, but the approaches, training structures, and organisations are distinct.
