A. Yes they all need to be taken in order because they build upon each other. However, since we do offer this course several times a year, there may be an option concerning the first module (Sacropelvic module) which if missed may be able to be taken possibly in the 5 week course session which coincides with the spring course. For more details please contact Robbie at 309-658-2920 and she will be happy to assist you.
