Mike and Brenda Acosta•Executive Director

Pastor Mike and Brenda Acosta have an extensive background in ministry and have been on the staff of Grace Church, a multi-cultural, multi-generation church meeting at four separate campuses around the Greater Houston Area, since 2004.

God has given Pastor Mike a special vision to help build leaders and to equip and release the next generation of Christianity around the world. In addition to leading Grace Church’s missions efforts, both around the globe and in the local community, Pastor Mike serves as the Executive Director of ImagineNations, which he co-founded in 2005. 

Pastor Mike first felt the tug of missions before he even knew what the word meant. As a young boy growing up in a small town in East Texas, he would pour through books at his grandparent’s house and dream of exciting places around the world. As a young man, he joined the Army and was honored to serve in the elite Special Forces in many locations around the world. Little did he know that he was just beginning to scratch the surface of all the places God would take him. 

Pastor Mike is a three-time IronMan finisher, and he has helped train many others in their journey to complete their own IronMan challenge. 

Pastor Mike and Brenda have three beautiful daughters — Ashlie, Megan and Isabella.

HOllIE PERRY • National and local partner Liaison

Hollie Perry serves as the National and Local Partner Liaison of ImagineNations. She has been involved in missions work and student ministry with her local church for more than half of her life. 

She has an extensive background in full-service Hospitality Management with several of the largest international hotel chains, and in 2012, she left her position at one of the top producing hotels in the US to work full time in ministry. Many thought her unwise as she was a single woman who had just purchashed her first home. She was told it was not financially smart. She would shrug and respond “do what you love and love what you do – and live on a budget.” 

She is hyper-organized and can never pass up a chance to color code anything, but her real love is people. She loves to hear their stories and wants all the details of their life. She loves traveling and seeing what God’s people are doing all over world.

Hollie is fanatical about her morning cup of tea and is an avid cruiser. She is forevermore counting down the days to her next cruise.  

Alone we can do so little; together we can do so much.
