The National Solitary Project

What Is The National Solitary Project?

In 2016, The Lionheart Foundation received a major “Innovative Grant” from the California Department of Corrections and Rehabilitation (CDCR) to deliver the Houses of Healing Self-study Program to individuals housed in CDCR Special Housing Units (SHUs). More than 500 men participated over a 2-year period. The program evaluations provided invaluable feedback and spoke to the positive, and often life-transforming, impact of the program for many participants.

As a result of its exceptional impact, Lionheart decided to make the Houses of Healing Self-study Program available, for free, to people in highly restricted housing units nationally. Toward this end, The Lionheart Foundation launched The National Solitary Project.

Lionheart is partnering with state and federal prisons throughout the U.S. to make this acclaimed, evidence-informed program available to incarcerated individuals who are in highly restricted housing units (equivalent to solitary confinement). Lionheart is, for a limited time, providing the program at no cost.

What Is the Houses of Healing Self-study Program?

The Houses of Healing Self-study Program consists of the book, Houses of Healing: A Prisoner’s Guide to Inner Power and Freedom and the accompanying Making Time Count (MTC) workbook. The workbook walks participants, step-by-step, through the Houses of Healing Program. It is for anyone with a modest reading level (6th grade), a pen or pencil, and a willingness to engage in rehabilitative programming. While MTC can be used by most anyone in prison, including in group programs in the general population, this free offer is for highly restricted housing only.

Who Can Participate in The National Solitary Project?

Lionheart will be distributing the Houses of Healing / Making Time Count resources to individuals in solitary confinement. To ensure we can reach a significant number of people in solitary, for a limited time Lionheart is providing this program at no cost to prisons that meet the following criteria:

  1. Only those in solitary units are eligible to participate (single bed / locked in 22-24 hrs/day with little to no access to other programming). It is important to note that this program is NOT for individuals with severe mental health issues.
  2. Each institution will need to identify a contact person at the prison (i.e. program personnel, chaplaincy, mental health, or other staff) who will be responsible for distributing a program announcement and registration form to those in solitary in order to recruit participants. Lionheart will provide a file with these forms. The only out-of-pocket cost to the institution is to photocopy and distribute these 2 pieces of paper. The contact person will also be responsible for receiving the program packets from Lionheart and distributing them to registered program participants.
  3. Lionheart requests that the 1-page registration form be scanned directly to The Lionheart Foundation by the staff person who is supporting the initiative. Program packets (with book, workbook, introductory letter, program evaluation and bookmarks) will be mailed directly to the prison contact person.
  4. As noted, Lionheart will provide an evaluation (to gauge the level of participation and effort) that the participant mails back to Lionheart (in a pre-metered envelope) at the end of the course if s/he wishes to receive a “Certificate of Completion”. (Lionheart provides this certificate if s/he demonstrates a sincere effort.)  We make it clear to prospective participants that Making Time Count is a self-study program NOT a correspondence course.

Because the Making Time Count Self-study Program requires significant time and effort on the part of the participant, to demonstrate effortful participation we encourage that the institution/prison system provides its own incentivization to promote program engagement and completion.

Example: the California Department of Corrections and Rehabilitation (CDCR). Once participants in the SHU have returned the evaluation and assignments demonstrating a sincere effort, Lionheart sends a “Certificate of Completion,” a congratulatory letter directly from The Lionheart Foundation, and a form created by the CDCR to the program liaison that is put in the participant’s prison/parole file.

Overview of Lionheart’s History in Corrections

The author of Houses of Healing, Robin Casarjian, with a group of successful participants in our prison rehabilitation program.

Over the past 28 years The Lionheart Foundation has distributed more than 180,000 copies of Houses of Healing to prison libraries and programs (70,000 donated). Although the book can be read on its own, it is also part of a larger curriculum which includes the Houses of Healing Facilitator’s Manual, the Houses of Healing Video Series, and, as of 2020, the Making Time Count workbook which is used in conjunction with the Houses of Healing book. In August 2023, Lionheart launched the 14-session Houses of Healing E-Learning Program for use on tablets which thousands of incarcerated learners now have access to.

In 2021 the Houses of Healing Program was listed in the Federal Bureau of Prisons Approved Programs Guide for the First Step Act. In 2021, 72 Federal Prisons across the U.S. have purchased more than 10,000 Houses of Healing resources.

During the past seven years, Lionheart has received seven “Innovative Grants” plus a RIGHT Grant (Rehabilitative Investment Grant for Healing and Transformation) from the California Department of Corrections and Rehabilitation (CDCR) to provide our programming to a wide range of incarcerated individuals. The first of these grants provided a 14-session program based on Houses of Healing to more than 400 men in CA Special Housing Units (SHUs) who voluntarily registered for the program. With an unprecedented data set of 187 evaluation responses from men in the SHUs over a 2-year period, 100% of respondents indicated that they would recommend the program to others. Since that time, many more incarcerated individuals in CDCR highly restricted housing have participated in the program.


The Making Time Count self-study program is for anyone with a 6th grade reading level, a pen or pencil, and a willingness to engage in rehabilitative programming. While Making Time Count can be used by most anyone in prison, including in group programs in the general population, this initiative is specifically offered as a self-study program for individuals in highly restricted housing.

Research findings (The American Journal of Forensic Psychology and The American Journal of Forensic Psychiatry) and hundreds of program evaluations and unsolicited testimonies from incarcerated men and women speak to its life-changing impact.
