Tiffany Gillespie

Chief of Staff

“As Chief of Staff, I seek to translate the church’s mission into ministry. As a consequence, I’m directly responsible for leading the ministry program staff as they seek to fulfill the congregation’s mission and vision.”

Tiffany Gillespie is a strategic event coordination expert, small business development strategist and 4 time author. She is the lead designer and founder of To the ‘T’ Events and The Purpose Seekers Academy.

Just before having a crucial brain surgery, Tiffany made a promise to God that if He allowed her to survive she would live life out loud and walk in her purpose every day.

The on-fire entrepreneur is constantly sought out by individuals and organizations across this country who ask her to speak to their audiences, grow their businesses, train their classes, and plan outstanding events. As a result of all of this, Tiffany has netted the following accolades:

Antwine Stokes

Minister of Music

Antwine Stokes is a Philly native and lover of all music but most of all, gospel and worship music. He got his start in his mother’s church at the young age of 4 years old and now at the age of 31, he is still singing for the service of the Lord.

Antwine has always been a lover of music and the preached word. Born in Philadelphia and raised in various small towns in Pennsylvania, Antwine’s mother never failed to keep him in church. Even with the responsibility of raising six kids, she always made her children understand that God comes first in everything they do. Although Antwine loved music all his life and was still singing, he didn’t receive any formal training until he began 9th grade when his family moved back to Philadelphia. Under the teaching of many high school teachers and choir directors, he began to realize his passion…singing.

In 2001 for a very short period, he joined the Philadelphia Boys Mass Choir, his high school choir, and even an R&B group. In 2002 he moved to Norristown, PA where he lived until he graduated from high school. He joined The Historic Ebenezer Methodist Church where he cultivated his singing skills and knowledge under the leadership of Bishop Albert N. Jarman. He remained a member until he joined Catalyst for Change Church under the leadership of Pastor Keon A. Gerow in 2010.

Antwine sings as a member of various local choirs including the GMWA/CAD Philadelphia Chapter Choir, Ebenezer Methodist Church Concert Choir, The 300 Gang, The He’s Alive Choir, Nick Reynolds and Family Affair, and The Catalyst Church Choir where he serves as director. His main focus is always been to use his gift in music to glorify God. He serves as the worship leader, choir director, and minister of music for Catalyst Church. His main focus each Sunday is to glorify God with all the ability of his gift without holding anything back and giving God all. He understands the role that he plays at Catalyst Church and knows that music is the drawing piece but the anointing and the word of God is the changing force.


Elder Benson Williams 

Director of Discipleship

A native of Philadelphia, Pennsylvania, born the seventh of eight children on April 15, 1964 to Mr. & Mrs. Joseph Lee Williams Sr., I am blessed to serve Catalyst Church as Director of Discipleship. This role requires passion for working with adults of all ages, and the congregation at-large to embody the mission of Catalyst Church as a place where Christians “evangelize the sinner, equip the saint, and elevate the Savior” through discipleship and relational ministries such as small group opportunities, new member connection, Next Level Living Academy, Biblical Empowerment Training (B.E.T.), and social events.

The Director of Discipleship develops, schedules, and supervises the full range of ministries related to adult discipleship and connection. Having been licensed and ordained, I enrolled in the Center for Urban Theological Studies which is also underwritten by Geneva College to obtain an Associates degree in Bible Ministry and a Bachelors degree in Human Resources/ Business Management, as a Magna Cum Laude graduate. Lastly, I am a graduate of Lutheran Theological Seminary, obtaining a Master of Divinity.
