Lindsey Stephenson, LSCSW
President
Lindsey Stephenson, LSCSW, has been with KVC for 15 years and previously served as Vice President of Operations for KVC Kansas based in Olathe. In this role, she led a team that dramatically grew community support for children who are in foster care due to abuse or neglect, increasing the organization’s foster and adoptive families by 78%, from 500 to 892 homes. She also expanded community partnerships, such as collaborating with Global Orphan Project’s CarePortal to create Protective Homes in Kansas and worked with community mental health centers and churches to strengthen families and safely prevent children from entering foster care.
Stephenson led the transformation of KVC’s youth residential center in Kansas City, KS into a Qualified Residential Treatment Center (QRTP), in line with the federal Family First Prevention Services Act. This treatment center is licensed to care for up to 16 adolescent youth with mental and behavioral health needs at a time by offering comprehensive services and helping them successfully transition back to family-like settings with relative caregivers, foster family homes, or their birth family homes.
In addition to overseeing KVC Kansas’ Child Placing Agency (CPA) and QRTP, she oversaw its Admissions, Quality and Data Management, and Community Outreach teams. Stephenson received her graduate and undergraduate degrees in social work from the University of Kansas.
Stephenson was named President of KVC Missouri in June 2021. She also leads new partnerships and collaborations.
