Barbara Dehon-Manuel, LCSW

Health Center Manager, Social Service Coordinator, Gentilly Family Health

Ms. Dehon-Manuel has been an employee of EXCELth, Inc. for over 25 years. She started out providing case-management services to clients. From here, with the assistance and support of a strong team, she had the success of establishing the Social Service Department.  Because of its proven success record, the Social Services Department has often been charged with additional responsibilities, as needed, to ensure the viability of other programs within the agency. These additional programs have included the Ryan White HIV/AIDS program and the CDC HIV/AIDS program. The Social Services Department, under her leadership, has always delivered high levels of excellence no matter the challenge. Along with kind, compassionate care for her clients, she has exemplified strong leadership as the Coordinator of the Social Service Department. Currently, she is serving in the role as the Health Center Manager for the Gentilly site. This role certainly places her more on the administrative side of things, but still allows her to utilize her social work skills. As she loves to say: "I was born a social worker, I will be a social worker, and I will die a social worker." She is inspired by EXCELth because of its commitment to the staff, the community, and the people we serve. She believes this allows her to serve God through meeting people's needs. Her hobbies/interests are quite simple - spending time with family, reading the Bible, and playing with her fur babies (Ollie & Remi). However, in addition to her professional achievements, Ms. Dehon-Manuel's greatest accomplishments have been her children, Jai’Juan and Holton. They have made parenting loveable, enjoyable, and easy. She loves them dearly.
