Phyllis has six grandchildren ranging in age from 9 to 31. Since Dennis was an oil field engineer, they moved around a lot. Phyllis received undergraduate degrees in Biology from University of Texas, Austin, and in English from University of Texas of Permian Basin in Odessa.  After working at Southwestern Medical School in Dallas for several years, she returned to the UT system to study geology, receiving her PhD.  She worked as an oil and gas explorationist for 14 years before leaving to attend Southwest Baptist Theological Seminary.

She began teaching at Baylor in 2001, and continued until her retirement in 2011.  Phyllis was ordained as a Baptist pastor in 2008, the first woman to be ordained in her church, so that she could continue to act as part-time pastor for Providence Retirement Center in Waco.  Phyllis served as the Sabbatical Assistant at TPC during the summer of 2014. She found TPC to be a place where she could be part of a genuine, caring group of people serving God, and she joined the church in the fall of 2014.

Joseph Whitner

Parish Associate

Joseph Whither is a native of Atlanta, Georgia and a lifelong Presbyterian. He is a graduate of Columbia Theological Seminary in Decatur, Georgia and served pastorates in Alabama and in Georgia. In 1968 he was called to Dallas, Texas to work as pastoral counselor with the Presbyterian Counseling Center. In 1985, he moved back to Georgia with his wife, Katherine, to develop a retreat and spiritual renewal center in the North Georgia Mountains. This enterprise became very successful, and after eighteen years, it was sold so they could move back to Texas to be closer to children and grandchildren.

His calling and purpose is to be an interpreter of the traditional understanding of the Bible, God and Jesus into language that can give new meaning, faith and purpose to our lives in the 21st Century. His hobby is writing poetry in which he expresses his experience of the joy and meaning of life. It is his delight to see how psychology, science and religious beliefs, and feelings can all be blended to give us an increased sense of what we have come into this world to be and to do.
