Timene Farlow
Deputy Commissioner

Timene Farlow, Deputy Commissioner for the Division of Juvenile Justice Services began her career with DHS in 1995 as a social worker. Her first job was in the intake unit, conducting investigations of alleged abuse and neglect and then transitioned to Adoptions as a supervisor. Convinced that her true passion could be lived out working primarily with adolescents, she began  working at the Youth Study Center, the City's only secure juvenile detention facility, in 1999.  Later, she left the Youth Study Center to take on the role of Director of Court and Community Services, a position which served to broaden her exposure to the larger  juvenile justice system and which greatly aided in her acquisition of the skills and understanding needed for her current role as the Division's Deputy Commissioner.  

Ms. Farlow is passionate about her work and is a staunch advocate for youth in the juvenile justice system.   She has a special interest in gender-responsive services for females as well as the issue of disproportionate minority contact and confinement.  She firmly believes that the needs of adjudicated youth can best be met through quality, evidence-based programming which looks not only to address the delinquency needs, but the unresolved dependency needs with which many of these youth also present.      

Ms. Farlow is a native Philadelphian who attended LaSalle University for undergraduate studies and received her MSW from Temple University. She has one adult daughter and a teen-age grand-daughter.
