Ministerial Staff

Dr. Sean McMillan,  Pastor

The ministry of Dr. Sean centers on the psychological, spiritual and social implications of love.

Loving people is about building community. Saving Souls is about introducing people to the saving power of Jesus Christ. We exist to save souls. And saving souls is really about saving lives. Our mission is to sow the seeds of life by declaring the Gospel of Jesus Christ in word and deed.
It is the mission of St. Mark to be a Godly community church where people are nurtured, inspired and empowered to live out their Christian witness.
