I also have a son receiving special ed services in Sudbury elementary schools. He started in preschool and we have been very happy with the team for the past 7 years. We are gearing up for middle school and working with my son's team to ensure there is a solid IEP in place to support him.
You can visit http://sudburysepac.org for more information on the Sudbury Special Education Parent Advisory Council. I am also a realtor in Sudbury and would be happy to help you further.
