Los Angeles ( CNN ) -- Chris Brown has `` made significant strides '' in staying sober since he got out of jail in June , the singer 's psychiatrist said . The doctor 's letter to Brown 's probation officer said he 's `` working on personal growth '' and `` is taking responsibility for his behaviors '' in the two months since he was freed from jail . Those behaviors have included an alleged sidewalk fight that sent him to jail in Washington , D.C. , in October and a violent outburst that got him booted from a drug rehab program in November . The doctor 's treatment is part of his probation sentence for an attack on then-girlfriend Rihanna in 2009 . Brown , 25 , was in a Los Angeles court on Wednesday for a status hearing on his probation , which will end on January 23 , 2015 , as long as he stays out of legal trouble and completes another 600 hours of community labor . Judge James Brandlin praised the singer for his favorable probation report , which is a contrast to several recent reports that culminated in Brown spending four months in court-ordered rehab and three months in jail . `` Mr. Brown has made significant strides in maintaining his sobriety , as well as developing skills that promote personal growth , '' wrote the doctor , whose name was deleted from the report .

He still faces trial this fall in Washington on a misdemeanor assault charge stemming from the sidewalk fight . He was booted from one rehab facility in November because he stormed out of a family counseling session and smashed the window of his mother 's Mercedes with a rock . But Brown is taking his twice-a-week court-ordered psychological therapy sessions seriously , the doctor said . `` He continues to show great perseverance in implementing recommendations made by his treatment team , utilizing his learned skills and seeking guidance in his recovery process , '' his doctor reported . Brown 's efforts to remain calm and in control appeared successful at the courthouse , despite some tense encounters with the news media covering Wednesday 's hearing . He quietly watched as a TMZ reporter attempted to get on a courthouse elevator with him after the hearing . He left it to bodyguard Christopher Hollosy to repeatedly nudge the reporter until he was out the door . Hollosy , a large man who is fiercely protective of his client , was found guilty in April of attacking the same man in Washington that Brown is accused of hitting . When he encountered news photographers at the front courthouse exit , Brown retreated to a rear door , appearing unshaken and unemotional . The only woman with Brown at Wednesday 's court date was his mother . She has been with him at almost all the hearings , except immediately after the window-smashing incident .

She has attended most of Brown 's recent hearings , including the last one in May . She was not in court Wednesday .
