The UUSGU holds weekly formal Sunday morning services from September to June in the sanctuary of the church from 10-11 am. Service is varied in style and content, generally led by Rev. Roger Peltier and followed by an informal social hour. We entertain occasional guest speakers.

Children participate in the 1st part of the service then go to their respective classes, except for the five annual intergenerational services. Childcare for infants and toddlers is provided. Periodic brown-bag lunches and committee meetings follow the social hour.

Lay-led summer services are held from 9-10 am.
