Charles Anderson, Re-Entry Discipleship Program & Housing Director

Pastor Charles Anderson is a native of Alexandria, Louisiana.   During his service in the U. S. Army at Fort Polk in Leesville, Louisiana, he answered the call to preach at the age of twenty-three.  In 1990, Pastor Anderson was licensed and ordained to preach the Gospel at Greater New Hope Baptist Church in Alexandria, Louisiana, under the leadership of Senior Pastor Reverend Simm James.

Charles studied Human Behavior at Leal College and Graduate School, St. Ann, Missouri. Over the years he has pastored and lead several congregations: New Life Church, World Conquerors Baptist Church, and Good News Baptist Church all in the ‘Show Me State’ of Missouri.

Pastor Anderson served 10 years in the U. S. Army. He was honorably discharged in 1992 and went on to pursue a career in corrections.  With over 15 years’ experience working in corrections in Illinois, Missouri, and Texas, Charles developed a heart and compassion for the literal and figurative captives inside the prison walls. In recent years, he has committed himself to teaching weekly Transformation Bible Study Classes inside Texas Department of Criminal Justice.  From this experience Charles launched The Urban Ministry Institute -Houston and implemented TUMI classes inside TDCJ for the modern day Onesiumus’s of our time, the runaway slave that the Apostle Paul speaks of in the Book of Philemon.

Charles is especially committed to the lives of those behind bars and their families, so that they may come to understand they’ve been bought for a price, their lives are not their own, and they are here to accomplish His work – for God’s Kingdom purposes.  His obedient servant-hood to those still incarcerated, is that these people have eternal value, the can proclaim the Gospel in Word and deed if disciple and taught, equipping them to be “useful” in serving God through serving others.

Pastor Anderson carries a deep and profound conviction that his life is meant to be laid down fully in order to lead, shepherd, disciple and equip the saints to do battle, taking territory from Satan, in this broken world.  To do so, God has prepared Charles throughout his life, for such a time as this.

Charlie Montes, Intake Specialist

Charlie MontesCharlie is first generation born and raised in Houston by his family who immigrated from Cuba. In his early adulthood, he went to the Gus George Law Enforcement Academy to become a police officer and served in law enforcement for almost five years.  After completing his Bachelor’s degree in Mechanical Engineering, Charlie entered the Oil and Gas industry, where he worked for over 10 years as a Project Manager and General Manager overseeing and assisting with the design of custom, highly engineered industrial equipment packages.  It was during this time that Charlie was faced with incarceration.

While Charlie was incarcerated, he witnessed the stigmas and institutionalization that occurs from being imprisoned.  It was during his incarceration that Charlie re-dedicated his life to Christ and began to actively walk with Jesus.  When Charlie released from prison, he learned firsthand the barriers and obstacles men and women face as they try to re-enter society. This is when God placed on his heart that he must do something to help those facing the same obstacles and barriers he was confronted with.  It was a relatively a short time afterward that God led him to Crosswalk Center, where he instantly knew he was meant to be.

Charlie is now working on his Bachelor’s in Business and is seeking to become certified as a counselor to better suit the needs of the residents he works with on a regular basis.  He believes he can be an example of where God can lead you when you decide to trust his plan and no longer lean on your own understanding.  He wants to give everyone who comes across his path hope that they can achieve all things through Christ, regardless of their past indiscretions.
