Online Certification is taught by Dr. Perkus and assistant instructors. 

You meet weekly for an hour online for 8 weeks, plus participate in online mentoring groups and complete assignments.

In-Person Certification is usually done over a weekend, with additional online support afterwards.

Immersions are 4-5 hour, in-person classes that allow you to "dip your toe in" and see if Certification is right for you.
