Sylane Mack

President, Principal Speaker, Lead Counselor, Author

Transformed By Grace, Inc.

Sylane holds a BA from State University of New York at Potsdam and an MS from California State University at Fullerton. Now a national and international speaker and author, Sylane began speaking in the mid-1970s, declaring the power of Jesus to heal and transform the most broken of lives by His love, Word and Spirit. From the darkness of horrendous abuse, God brought His light and power to forgive into Sylane’s life! In 2003 God birthed Transformed By Grace (TBG), a Counseling and Conference Speaking Ministry; in 2017 God established TBG’s Counseling and Wellness Center in Pennington, NJ. Sylane’s deepest desire, whether in the counseling room or the conference room, is to point others to the Lord Jesus and His power to preach good news to the poor, bind up the broken-hearted, set the captives free, bring the prisoners out of darkness…and plant them as oaks of righteousness…for the display of his splendor! (Isaiah 61:1-3).  Sylane married her high school love, Tim, and they have two daughters, two sons-in-love and, so far, one grandson.
