Mark went to the University of Chicago on scholarship playing basketball and majoring in pre-law. After a prayer walk through a cow pasture, he felt called to full time ministry and ended up at Central Bible College in Springfield, Missouri. That's the short story. Mark also holds a Doctor of Ministry from Regent University. He is the author of a dozen books including his first published title, In a Pit with a Lion on a Snowy Day and The Circle Maker, a New York Times Bestseller.
Mark and his wife, Lora, moved to Washington, DC, in 1994 to direct an inner-city ministry. He has served as Lead Pastor of National Community Church since 1996. Under his leadership, NCC has grown from a core group of 19 people to one church with multiple locations.
Mark and Lora live on Capitol Hill and have three children: Parker, Summer, and Josiah.

Hunter is originally from Columbus, Ohio, but came to us in 2019 from Lakeland, Florida, where she graduated from Southeastern University with a B.S. in Practical Ministries. Passionate about development, and with a background in ministry and project management, Hunter feels like she’s doing what she was born to do when she gets to partner with others and participate in bringing dreams to life. If you’re familiar with the Enneagram or Myers-Briggs, she’s a 1w2 and an ESFJ. You can often find her with a cup of coffee, which is funny considering the fact that she used to say she would never drink coffee, but is now an aspiring coffee connoisseur. She also really loves spending time with friends and family, storytelling, and sweets.
