On August 1, 2023, Rev. Dr. Mixon started as Interim Senior Minister of Old Cambridge Baptist Church in Cambridge, Massachusetts. Rev. Dr. Mixon is an ordained American Baptist minister with over 30 years of experience in pastoral ministry, church leadership, and social justice advocacy. He has been involved in various regional and national organizations. These include the Alliance of Baptists, the Association of Welcoming and Affirming Baptists, and the Baptist Peace Fellowship of North America. Rev. Dr. Mixon also holds a Master of Science in Marriage and Family Therapy from California State University and a Doctorate in Religion and Psychology from Graduate Theological Union.

Donald and Bertha graduated in 2025 from the Master of Divinity program at Berkeley School of Theology. In addition to earning their degrees, the couple has another reason to celebrate: They were united in holy matrimony on Saturday, September 13, 2025!

Meeting at BST, a friendship that began over Zoom blossomed into relationship, culminating in an engagement on the day prior to their graduation.

As one professor at Commencement exclaimed, “How could this have happened Zoom?!” Their answer is, “With God, all things are possible!” After their wedding, Don and Bertha will launch their new ministry, “Intercultural Prophetic Ministries,” in the Biloxi, Mississippi area, where they reside. They are also continuing to work on a ministerial project already in progress in the Bay Minette, Alabama communities. Please continue to keep them in your prayers as they begin this new chapter together.
