Case Manager

Learn More About Alex

My passion for helping others comes from both my professional experience and my personal journey. Having lived a life impacted by addiction, I understand firsthand the pain, loss, and struggle that can come with it, but I also know the power of recovery and what it means to rebuild from the ground up.

I know what it feels like to be alone at the lowest point in life, and I also know there is hope, healing, and light at the end of that darkness. Change begins when a person becomes willing to take that first step, even when it feels impossible. That moment of willingness can be the start of everything.

My journey of transformation has inspired me to dedicate my life to helping others find their way back to themselves. I believe every person deserves compassion, respect, and the chance to start over, no matter their past. I am also passionate about helping reunite families and restoring relationships that addiction has strained or broken.

My goal is to create a safe, honest, and supportive environment where clients feel seen, heard, and never judged, only supported. I am committed to walking alongside each person as they work toward healing, stability, and a better future.

Outside of work, I enjoy weight lifting, cooking, watching movies, playing sports, reading, and spending quality time with my wife, son, and our dog. I am continuing my education as I work toward becoming a Certified Alcohol and Drug Counselor. It is an honor to be part of each client’s journey toward hope, healing, and lasting recovery.
