Founder & CEO
Kirsten MacArthur is the Founder and CEO of Chrysalis Recovery Center LLC (CRC-IDCMP). Since opening the doors in April 2009, she has led the organization with heart and soul, operating on the firm belief that every client matters. Her vision has created a supportive environment where individuals are treated with dignity and respect. Under her leadership the agency has served well over 25,000 clients.
A veteran of the field, Kirsten has been working in substance use and behavioral health services since 1996. She earned her first license in 2004 and has successfully maintained licensure across five different states (AZ, MA, NH, VT, ME) throughout her career. Her specialized qualifications include being a Certified Anger Management Trainer (CAMT) since 2009, and a designated Substance Abuse Professional (SAP) for the Department of Transportation since 2018, authorized to conduct DOT evaluations and counseling.
Kirsten brings a unique blend of clinical expertise and administrative leadership to the center. She has personally completed IDCMP evaluations for about thirteen years, and she developed the organization's policies and procedures, its record systems, its reporting and audit processes, and its in-house training for clinical and support staff. She also oversees billing, insurance credentialing, human resources, and budgeting for the agency.
Kirsten has never been far from the work itself. She also held a contract through Keystone Hall in 2011–2012 as a provider for the Department of Justice's Offender Re-Entry Services Initiative (ORSI), supporting clients leaving prison as they reintegrated into the community. Over the years she carried her own client caseload as a counselor at Chrysalis, running intensive outpatient programming along with individual and group counseling. She also secured a three-year contract through the Easter Seals Deployment Cycle Support program with the NH National Guard, from 2010 to 2013, providing in-home counseling and case management for service members and their entire families — before, during, and after deployment.
Before founding Chrysalis, Kirsten worked as a Case Manager with the Merrimack County Diversion Program — collaborating directly with prosecutors, judges, attorneys, and police to ensure people arrested on drug charges completed their court-ordered care — and as Assistant Director of the grant-funded Project Recovering Lives at Keystone Hall in Nashua. Earlier in her career she developed and directed an adolescent intensive outpatient program in Arizona and worked as a Behavioral Health Technician on a child and adolescent inpatient unit.
Kirsten holds a Master's degree in Business Management from New England College, a Bachelor's degree in Clinical Psychology from Keene State College, and an Associate's degree in Chemical Dependency from Keene State College. She also owns Recovery Residences Northwood LLC, a men's sober living program in Rockingham County — a property that formerly operated as a motel, where the IDCMP overnight weekend class has been held, and which is now growing into sober living.
