“I liked how direct and honest the author is. No fluff, no trying to sound fancy. The conflict-resolution bit is something I’ve already tried in real conversations, and it works better than I expected.”

“This program gave my loved one something meaningful to focus on while incarcerated. He completed the workbook on his own and was genuinely proud of the certificates he earned. It helped him build practical life skills and confidence, not just pass the time. I could hear the growth in his mindset every time we talked. I highly recommend this to anyone supporting a loved one’s rehabilitation.”

What participants say about Inner Change, Outer Impact
Anger management has helped me a lot with managing my anger and the way I respond to it today versus how I used to respond in the past. The parenting course helped me as well because this program lets me know that, even though I’m incarcerated, I can still be a father to my children.
Johan Batista
Parenting & Anger Management
You have put together, in my opinion, the most powerful program that I have ever gotten access to over the 22 years of my incarceration. It has furthered my growth and transformation and equipped me with the right problem-solving tools.
Larry Davis
Personal Transformation
I have been trying to enroll in an anger management program for some years now and have been ineligible to attend. I am extremely grateful to Dr. Hall for creating the IC~OI programs and making them accessible to individuals where programming may not be readily available.

Human Impact Stories
After years of feeling increasingly disconnected from his son during incarceration, M. Daley used the communication guidance in Parenting from the Inside — focusing on warmth, honesty, and sharing his growth without guilt or pressure.
“He came to see me for my birthday… The fifteen years I’m locked up, it’s the best birthday I had.”
— M. Daley
Ganesh used ICOI to examine childhood trauma, substance use, communication, and longstanding patterns in his life, later incorporating what he learned into his work as a peer supporter and facilitator.
“This program helped me to understand me — who I am. It gave me a purpose to live and help others walking in my shoes.”
— Ganesh, Cheshire Correctional Institution
