Rev. Doug Gebhard, Interim Pastor

Doug (as he prefers to be called) grew up in Penn Hills, did his undergrad work at Pitt, and received his M. Div.. from Pittsburgh Theological Seminary. He’s a hometown boy. His early ministry was with installed positions but he eventually discerned a calling to interim/transitional ministry. Certified in interim ministry in 1998, Doug has served churches in PA, NC, FL and NY. He’s also served a Moravian congregation in NC and, most recently, a Lutheran church in Western PA. He specializes in helping congregations through the pastoral call/placement process. Doug and his wife Dr. Susan Gebhard (“Dr. G.”) have been married for 28 years. Susan is an educator and has been a classroom teacher, school administrator, college professor, and is currently a gifted support provider. They have three grown children: Xandra (Adam), Mairé, and Mac. They live in Sewickley with their Golden Doodle “Yankee” and Irish Wolfhound “TirNa.”

Tom Ribar, Associate Pastor of Youth and Families

My most cherished gift is my wife, Tami, who I wed in December of 1985!  We have three grown children, Jessa (Ian and Avery) Darwin, Lexi Ribar, and Nathan (Lydia) Ribar.  Tami and I live in the Garfield neighborhood of Pittsburgh, where we enjoy being close to our children, and particularly being grandparents!  In addition to enjoying the labor of creating a hospitable home (a seemingly never-ending rehab, 4 years in the making!) that represents Jesus’ kingdom of shalom, we are blessed by good friends, city life, the beach (when occasion allows!), biking, and gardening.  Having grown up in Cleveland, OH, I have maintained my loyalties to Cleveland professional sports, despite living and working in the heart of Steeler nation (longsuffering produces in me a capacity to endure all things)!
My journey as a teacher and preacher of the Gospel began in earnest at Muskingum College (1984).  After several years working in campus ministry with the CCO in western PA, I completed my Master of Divinity at Gordon-Conwell Theological Seminary (1992).  I am currently finishing my Doctor of Ministry at Trinity School for Ministry in Ambridge, PA. 
I have worked in gospel ministry for over 35 years.  I have 20 years of campus ministry experience in student life, mission leadership, and teaching both in and out of the classroom.  I have served for over 15 years in a variety of pastoral roles with three different congregations.  This includes my current service as part-time pastor to the congregation of Mt. Pisgah Presbyterian Church in Greentree.  Nothing excites me more than helping disciples of Jesus grow in faithfulness by deepening their understanding of the Biblical story and our place in it.

Toni Schlemmer, Office Manager

Our new Office Manager, Toni Schlemmer also serves (evenings and weekends) as Director of Fine Arts at Calvin Presbyterian Church, Zelienople.

I am Associate Professor and Coordinator of the Music Education Program at Seton Hill University, Greensburg, PA. I have published research in various international and national peer-reviewed journals. I am also an active performer, clinician, and soloist. Previous to my graduate studies, I taught music in nationally recognized elementary, middle, and high school music programs in Indianapolis, IN.
My wonderful wife, Misty, is a counselor and instructor for various undergraduate and graduate psychology programs. We have two children, Amelia and Claire, who are great blessings in our lives. We also have a golden retriever named Lucy. If I am not working, I enjoy writing, reading, running, and biking. I also enjoy professional baseball, football, ice hockey, and college basketball. If I had a choice of another career, I would be a writer or author. I also enjoy traveling throughout the country and in Europe.

Rebecca Safko, Treasurer

I grew up in Marietta, Ohio and graduated from Marietta College, where I met my husband.  I received my MBA from West Virginia University.  I am a Certified Public Accountant.  I also work full time as the Executive Director of a multiple county workforce area in rural Southeastern Ohio.  We work with the employer customer and the job seeker customers by upskilling the workforce and helping job seekers on their career pathway to self-sufficiency. My husband and I have three wonderful children who keep us very busy:  Matthew, Jacinda and Suzanna.  I am blessed to also have my mother stay with us occasionally.  Working for Union brings great opportunities to make new friends and serve the Lord, thank you!

Taylor von Sternberg, Union Christian Academy Director

I have been with UCA since 2018, but recently became the Center Director in October 2021. Since graduating Indiana University of Pennsylvania in 2016 with a B.S. in Child Development and Family Relations, I have worked in the field of Early Childhood Education, and truly believe that it is my calling. It is a true blessing to have found Union Christian Academy. I love watching the children flourish and develop a relationship with God over their time at our center. Providing quality care and education for each individual child is my top priority. I have a daughter, Paisley, and a dog, Sawyer, who I adore! Paisley attends UCA, and I couldn’t ask for a better place for my daughter during her early years.

​Sally Andrews, Pastoral Care Coordinator

Sally has lived in Robinson for almost 80 years. Growing up, she walked with her mother and sister to Sunday School and church. Since then, she has raised her daughter in Union Church and is now sharing the importance of her church home and family with her three grandchildren. 

It is rumored that Sally can answer almost any question about the last 75 years of this church – or at least she knows where to go to find the answers.

 This church on the hill has been a major part of her life and she prayerfully serves with the hope that others may find Union Church a vital part of their lives as well. 

In her role as Pastoral Care Coordinator, Sally serves to reach out to the congregation and helps keep the pastor informed when members are in need of support, whether physical or spiritual.

I recently became the Sexton in March of 2022. That same month I also became a member of Union for which I am very proud. I am married to Kathy Pfaub Thomas.
