A collaborative project of The Jewish Federation of Greater Los Angeles, Jewish Family Service and seven other Jewish community agencies, HaMercaz (which means \”the center\”) assists families with children up to age 21 who have developmental and learning disabilities such as autism, ADHD (attention deficit hyperactivity disorder) or mental retardation. The two-year-old program serves as a \”one-stop-shop\” for families, providing guidance, support, education and referrals. Programs include a toll-free warmline; support groups for mothers, fathers and grandparents; and referrals to agencies that can provide assistance, such as interest-free loans or parent respite.
