BPI.org has a list of bpi trainers in the Boston area. You can check with these places to see if they have a course in auditing. You can join linkedin and then the resnet group and ask for training in the Boston area. Also, if you need IR training go to the Snell group and see when they offer training in the area.
Check community colleges to see if they have green collar auditing training.
Do you work with that organization? I tried to get a hold of the coordinator but it looks like she is on mat leave. I'm going to be in the Boston area for a few days in March and was looking to visit a few training centers, potentially give free training materials and do Retrotec equipment introductions for those interested.
They definitely are still in business. I teach their BPI courses for them. Silvie, you should conact Megan Amsler firstname.lastname@example.org I'm sure she would love to hear from you.
