Our Minister

Prior to his ministerial career, Greg worked in the arts, the food service industry, and for 13 years as a corporate business project manager for American Express.

In September 2018 Rev Greg began serving as the Regional Representative for the Great Lakes region of Unity Worldwide Ministries. As the Regional Representative Rev Greg mentors and ministers to member ministries, boards and ministers of the Great Lakes Unity region, and represents our region on the UWM Standards Team, which recommends standards and policies for UWM to implement within Unity worldwide. 

Rev Greg is in the process of earning his certification as a UWM Wellness Consultant/Specialist. He has completed many other skill development programs, including Mennonite Peace Mediation, Healthy Congregations Facilitator & Leadership Training, UWM Peace Making Skills Training and more. 

Rev Greg is married to an outstanding servant of Unity in his own right, John McMahon, who is currently an executive Board Member for Unity Worldwide Ministries, and liaison to multiple worldwide Unity teams. They share a son, Andrew, and two young granddaughters, Brianna and Lauryn, who live about a 4 hour car ride away, in Southern Ontario.  

Since coming to Unity of Bay City, Reverend Greg and John have brought creative change where it’s been needed, spiritually guiding us in our efforts to be a beacon of light for the world. Rev. Greg’s door is wide open to anyone who’d like spiritual counselling, or to give opinions, comments or suggestions – or, as often happens, just to say “Thank you!”   

Unity of Bay City has been blessed with Reverend Greg Coles as our senior minister since October 1, 2010. Reverend Greg is committed to leading us in co-creating a loving and inclusive community which provides practical tools to equip and inspire people to become all they are created to be. His vision is a world of peace, harmony and abundance made possible by honoring the Divine in each of us.   

Reverend Greg brings more than 15 years of ministry leadership experience within pastoral, large and corporate sized churches.  His first Unity home was Unity of Houston with Rev. Howard Ceasar, where Greg served on the music team and as director of theater for their Wednesday Night Live program. Moving to the Kansas City area, he served as Director of Worship & Volunteers for Unity Church of Overland Park, with more than 200 volunteers, 25 teams and 700 people attending each Sunday. There Rev. Greg oversaw key strategic initiatives including Vision Quest, Volunteer Appreciation events, and Fall Faith celebrations. In 2009 he completed the 3 year Master of Divinity program at Unity Institute, and was ordained in February 2010.
