About Trinity

After growing up in California, Hong Kong, New Jersey, and Kansas, Tim graduated with a bachelor’s degree in Electrical Engineering and a bachelor’s degree in Cognitive Science from the University of California, San Diego. He then worked for a bit in the Silicon Valley before crossing the continent once again to complete his Master of Divinity at Princeton Theological Seminary.

Tim began his pastoral ministry in Houston, at Clear Lake Presbyterian Church as Associate Pastor of Outreach and Evangelism. During his three years there he preached regularly and helped the church transition between senior pastors. In 2008 he became an associate pastor at First Presbyterian Church, San Antonio where he taught extensively as he worked with their Discipleship Ministries. While there, he met and married his wife Chalie (a native Texan and fellow engineer). In 2010 they made the move back to Houston, where Tim completed a Master of Business Administration at the University of Houston.

In early 2012, Tim accepted God’s call to pastor Trinity Presbyterian Church of Southlake where his contagiously energetic style of ministry continues today. Tim, Chalie, their daughter Emily, their son Jack, their daughter Kate, their daughter Lily, and trusty dog Frisco enjoy camping, movies, sports, eating guacamole and spending time with friends and family.

Ben was born in Paris, Texas. As a preacher’s kid, he moved across the country, calling Atlanta, Anchorage, and Harrison home at different times. Throughout his youth, he was drawn to ministry. He found his passion in organizing Vacation Bible School events, participating in liturgy, engaging young minds during children’s moments at church, and contributing as a member of the presbytery’s youth committee. Ben graduated from Missouri Southern State University with a degree in marketing. In 2020, his life took a joyful turn when he married Juliet and a few months later they learned that they were expecting their first child.

In February 2021, their daughter Mary was born. They found out that she was born blind and had to spend the first 2 weeks in the NICU. From there, Mary has not stopped amazing her parents with her determination, faith, and absolute joy.

During that time, they became house-parents at Goodland Presbyterian Children’s Home, and that job soon evolved into a fundraising role as Ben leveraged his marketing degree and his church experience. While there, he spent time with dozens of churches across Oklahoma and North Texas, getting to worship and learn with many different communities and people. Juliet also began her new studies at TWU in Denton in their occupational therapist doctoral program. They moved to McKinney and Ben started working at a local food bank. But Ben felt a calling back towards the community of church ministry. And in 2024 Ben became our Director of Discipleship as he leads us all deeper in our following of Jesus.

Ben, Juliet, Mary, and their 2 dogs, Winnie & Moose, all enjoy music, board games, roller skating, and hiking.

She loved the job, the pastors, and the people so much, she worked there for 13 years.
