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.
