Trettin is in the University District in the 2nd and 3rd floors of University Congregational United Church of Christ (UCUCC). When you arrive, enter through the sliding doors directly across from the parking lot on 16th Ave NE. You can follow the signs inside the church to get to Trettin. You will need to go through a locked security door once inside. Once you register, you will be able to enter with your own key card.

(206) 729-3723

Out-of-State Emergency Number: (406) 543-6952

*This number should only be used if there has been a disaster, such as an earthquake, and our phone lines are down. Our first priority is taking care of the children; we will then try to contact the out of state number. If a disaster has occurred and you call this number, you will most likely receive a recording stating the location of the children.


Our parking lot is directly across 16th Avenue to the East from the entrance of the church. The above photo is of the entrance to the parking lot. You will go up a hill to get into the lot. You may park there while you are dropping off and picking up your children. Remember your stall number and sign it in at the table just outside the church office. If you are visiting for the first time, you'll need to call 206-729-3723 to be let in. Once you are registered, you will have your own key card to access Trettin.
