Mimika Garesché

Ministry Consultant & Founder of the On Fire Discipleship Collaborative

Mimika’s track record of helping others achieve spiritual breakthroughs and the realization of new potential makes her a sought-after spiritual guide and an invaluable member of the Preambula Group.

She is the founder of the ‘On Fire!’ Missionary Discipleship Collaborative. This six-month immersive group experience has passed the 30th group milestone resulting in hundreds of amazing testimonials. It has helped others awaken a deeper understanding of God and helped them to understand their own gifts so they can live as missionary disciples where God has placed them.

In addition to extensive experience as a spiritual director and retreat leader for more than twenty years, she also founded A Path Toward Healing, which helps individuals work through and heal wounds suffered as members of the Church.


Mimika has her own amazing conversion story. Out of college she was hired to work with Citibank’s World Corporation Group and lived in Chile and Ecuador. She returned to New York to work in private banking where her clients included some of the wealthiest portfolios in Chile, Bolivia, and Peru.

Then God called her to use her gifts to bring others to Him. She changed her life trajectory and started to follow him which lead her to Pittsburgh, working in a seminary, college campus ministry and for the diocese before joining the Preambula Group.

She loves to read, fish, boat and take walks in nature. She loves a good laugh and finds life praying with others.


Mimika Garesché has an extensive education. Having earned advanced degrees in areas of study as diverse as ministry, business, education, and leadership provides a unique foundation from which to understand the human person.
