Our Leadership

PARKER ENG – Director of Astronomy & Technologies

Parker obtained a Bachelor of Business Administration in both Real Estate and Marketing from Baylor University in 1993.  He has been a real estate asset manager for over 30 years and is currently owner of Jill Parker Real Estate (residential brokerage) and Reallegiance Real Estate (commercial development).  A Christian since elementary school, Parker has always had a passion for encouraging Christians to build their faith and sharing the love of Christ and Gospel with others.  Parker currently sits on the board of several Christian ministries including Probe Ministries, Ask Nova, and now Worship In Motion & Day 4 Astronomy.  He is a former member of the Texas Astronomical Society and has been an amateur astronomer for over 20 years.  Parker and Jill, his wife of over 18 years, are decades long members of Prestonwood Baptist Church where Parker is a deacon and also director for Kerby Anderson’s Examine Sunday School Class for over 14 years.  Parker’s other interests include astronomy & telescopes, audio/video production, photography & astrophotography, drones, computers, gardening, event planning, and organizational leadership.  

JAMES WORRELL – Director of Astronomy & Education

James received his bachelor’s degree in geology from the University of Texas in Arlington.  He is passionate about revealing God’s power and majesty through the tools of astronomy.  James uses telescopes and the night sky to help build up the faith of the Church.  Originally a theistic evolutionist, he discovered his faith in secular opinion and old ages was inconsistent with a biblical worldview.  He has since become a biblical creationist and believes there is a great falling away within the church due to professing Christians supporting atheistic evolutionary ideas.  James’s hobbies include, hiking, backpacking, and studying ancient civilizations and their historical context to the Bible.  James has been married to his wife Rebekah for over 30 years and has three children.

PERRY HOLIFIELD – Director of Biblical Sciences

Perry studied Marketing and Management at Abilene Christian University.  He was marketing and sales manager for multiple advertising companies which took him to New Mexico, Nevada, and Hawaii.  Believe it or not, he doesn’t consider Hawaii a prize location, longterm.  He has been a Private Investigator since 1995 (it’s nothing like Magnum PI).  Bible studies with students from Taiwan, turned the focus of his investigative expertise to apologetics.  He joined Day 4 Astronomy in March 2021.  Perry has been married to his wife Teresa for 20 years and has two daughters.
