The ABC Team


Laura Haneline

Laura Haneline

Chief Executive Officer

In 2001, Autism Behavior Consultants (ABC) was founded by Laura (Roberts) Haneline and has been providing intensive behavior intervention to families in the L.A., San Gabriel Valley, and Inland counties. Laura has taken advocacy to the next step, by becoming one of the founding board members of LA FEAT. Having previously held the position of co-founding member of the South Bay GFCF group, which is now the South Bay chapter of TACA (Talk About Curing Autism), as well as a past member of the Autism Society of Los Angeles.

In 1998, Laura's son "Nicky", at the age of 3, was diagnosed with autism. Due to the limited number of agencies and long waiting lists in the area, Laura was unable to find a clinic based program for her son. With limited options, Laura and several other parents developed a workshop model program that ultimately formed Autism Behavior Consultants.

Due to her son's lifetime disability, Laura is currently exploring transitional services for both adolescents and adults. The journey of her son's development has given her the opportunity to meet amazing parents and build lifetime relationships. Laura's greatest gifts are sharing her personal experiences, knowledge, and resources.
