About First Covenant Treehouse Preschool

Treehouse fosters a Christ-centered environment that demonstrates a love for God and one another.


A well-rounded age appropriate curriculum is provided for academic, spiritual, emotional and social growth.  Activities include math concepts, language development, Bible stories, science, music and hands on projects.

We teach our children about God, our loving Father.  We believe that God loves and cares for all of us.  Our desire is to provide an atmosphere where each child can experience God's love through our actions and example.  We believe that such an atmosphere can help form a solid foundation of Christian values upon which our little ones will develop Biblical moral character and grow into men and women of strong faith in Jesus.

We provide a rich experience at Treehouse that will prepare our students for a positive Kindergarten experience.  Our students will gain confidence and competence and develop a strong, positive self esteem which will lead them to success throughout their lives.  Positive and healthy early childhood education and a strong Biblical foundation are a formula for a successful life. 

Our History

First Covenant Treehouse Preschool began in 1975 as a ministry of the First Covenant Church of Oakland.
