Ordered that the order of disposition is affirmed, without costs or disbursements.
As a threshold matter, the petitioner, Forestdale, Inc., established that it made diligent efforts to encourage and strengthen the parental relationship between the appellant and the subject child by, inter alia, scheduling weekly visitation and by providing referrals to parenting skills classes and anger management counseling ( see Social Services Law § 384-b [f]; Matter of Jamie M., 63 NY2d 388). Further, the agency established by clear and convincing evidence that, despite its diligent efforts, the appellant permanently neglected the subject child by failing to plan for his future ( see Social Services Law § 384-b [a]; Matter of Star Leslie W., 63 NY2d 136, 142-143). Although the appellant attended anger management counseling and completed a parenting skills course, the evidence demonstrated that he failed to gain insight into the issues which led to the removal of the subject child from his home. Despite the agency's efforts to assist the respondent father to improve his deficient parenting skills and to remediate his propensity for domestic violence, the father's aggressive and threatening behavior continued unabated ( see Matter of Nathaniel T., 67 NY2d 838, 841-842; see also Matter of Jennifer R., 29 AD3d 1005, 1006; Matter of Ajuwon H., 18 AD3d 752).
The finding that it was in the subject child's best interests to be adopted by his foster mother is supported by a preponderance of the evidence ( see Family Ct Act § 631; Matter of Star Leslie W., supra at 147-148).
