A visionary, strategic thinker and social networker, Mac delights in bringing movers and shakers together to transform their cities. Since 1995, he and members of his team have hosted urban consultations for more than 10,000 leaders.
Mac’s journey into leadership development began in 1983 after he and his wife traveled to Bihar, India to serve as short-term missionaries. As part of a ministry team that met weekly to pray for God’s intervention, Mac was a firsthand witness to the results of those prayers. Later, in 1998, after having lived in New York for some time but still recalling what had taken place in India, Mac founded Concerts of Prayer Greater New York (COPGNY), a collaborative prayer movement connecting pastors and churches throughout New York, New Jersey and Connecticut. Through his leadership, this united prayer movement became one of the most developed urban prayer and pastoral networks in the world.
After a 2007 survey revealed the time, financial and educational limits facing pastors, Mac founded The New York City Leadership Center (NYCLC) as a way of creating and coordinating leadership training and service opportunities to radically impact Greater New York, both spiritually and socially. Mac was also instrumental in founding the first annual Movement Day conference, established in 2010, as a way of catalyzing leadership teams from American’s largest cities to serve their cities more effectively through the advancement of high-level, city-changing collaborative partnerships.

A resident of New York City since 1984, Mac lives in a diverse neighborhood with residents from more than 100 ethnicities, and he attends church with people who speak 60 different languages. This daily interaction with neighbors and friends that literally come from around the world enhances Mac’s global view and attention to world issues. These relationships provide him with the determination that is needed to find solutions to the debilitating problems faced by so many, and to inspire leaders to work together to make the gospel relevant within each of their cities.
The Lausanne Movement—an international organization created to mobilize evangelical leaders to collaborate for world evangelism—has appointed Mac to serve in the volunteer position of senior associate. His role is to help expand their global networks, communicate their vision and further impact cities with the gospel of Christ.
Coauthor of The Power of a City at Prayer (InterVarsity Press, 2002), Mac also contributed to Signs of Hope in the City (Judson Press, 1997) and is author of Spiritual Leadership in the Global City (New Hope Publishers, 2008). His latest book is Consequential Leadership: 15 Leaders Fighting for Our Cities, Our Poor, Our Youth and Our Culture (InterVarsity Press, 2012).
After earning a Bachelor of Science degree in business administration from the University of South Dakota, Mac then continued on to earn a Master of Arts degree in religion from Trinity Evangelical Divinity School and a doctorate from Eastern Baptist Theological Seminary (renamed Palmer Theological Seminary). He enjoys music and the creative process of composing it. He wrote original music for his daughter’s wedding.
Mac and his wife, Marya, have been married more than 30 years, and have three adult children and two grandchildren.
