Sullivan Farm in New Milford has split from the Youth Agency, but will remain as an independent municipal entity.  The New Milford Town Council approved the change this week.  Sullivan Farm helps teach students about agriculture with a hands-on introduction to farming.  Former Youth Agency director Mark Mankin will oversee the farm as a consultant for $1 a year.  Survey results from middle and high school students prompted a change in program offerings by the Youth Agency, moving to a more therapeutic approach to help New Milford students.  The director will be Jason O’Connor. The federal workforce grant that helps employ teenagers will still bring Sullivan Farm and the Youth Agency together.
