• Rev. Brittany Tamminga

    Interim Associate Pastor


    extension: 122

    It is with great joy that Session announces the appointment of Rev. Brittany Tamminga as our Interim Associate Pastor. Pastor Brittany began her ministry at Trinity in August 2021. 

    Brittany brings an abundance of God’s love and a deep faith that will serve Trinity well during this upcoming period of transition. A Southern California native, Brittany graduated from Princeton Theological Seminary and has a strong background working as Director of Youth and Children’s Ministries in San Diego at Pioneer Ocean View Church and First Presbyterian Oceanside, where she fondly remembers Mexico Mission Trips with Amor Ministries. Brittany comes to us from Fredericksburg, Virginia where she served as Associate Pastor of The Presbyterian Church for six years. 

    Brittany possesses both pastoral and administrative gifts that have been honed while pastoring at churches of up to 1,000 members. She has provided worship leadership, shared responsibility for pastoral care and demonstrated a strong background in working to bring together an inter-generational congregation. However, it was her strength involving youth in the life of the church that most impressed the Interim Associate Pastor Search Committee. As she said, “On really good days, success in ministry looks like intergenerational education and fellowship, a text from a high school student with news of their college acceptance, or the small hand of a three-year old waving enthusiastically to those entering worship.” Both in her preaching and in conversation, Brittany radiates a love for people and a passion for learning people’s stories.

    Brittany and her husband Tim enjoy spending time with their many nieces and nephews. And in her free time, enjoys cooking, gardening and watching corny movies.
