Education Director

Pam Brockberg (she/her)

Together with the Board of Education, I plan, organize and carry out the educational ministries at Trinity.  We have Sunday school at 9:30 am Sundays for 3 year olds and up.  We have Confirmation on Wednesdays at 6:30 pm for students in 6th, 7th and 8th grade.  We celebrate many milestones in our students' lives, from baptism to graduation, through our Milestone Ministry program.  We arrange for the children's Christmas program, Vacation Bible School, acolytes and many other fun celebrations throughout the year with our families.  We also plan adult educational opportunities.  Please visit with me or a member of the board with suggestions or ideas or to volunteer to help.
