The ABA Team

acornABA was founded by Sarah Walker, a Board Certified Behaviour Analyst based in Northamptonshire.

She is passionate about behaviour analysis and it’s application to educating children on the autism spectrum. She has worked in the field for the last 10 years and has a wealth of experience across different settings.  Like many behaviour analysts, Sarah embarked on her ABA career initially as an ABA Tutor on home-based programmes whilst studying for her undergraduate degree.  Later she went on to train as a behaviour analyst with a well-known ABA School in Surrey. 

After completing her Masters degree in ABA with Nicholls State University in Louisiana and having achieved board certified status, Sarah embarked on her next adventure! In September 2015, she was part of the team of like-minded ABA practitioners appointed by the parent founders to help open and run the UK's first state ABA free school where she took on the role of Assistant Head Behaviour Analyst.

Over her professional career she has had the privilege of working with respected behaviour analysts from the UK, Italy and the Unites States.  She has had opportunities to expand her knowledge of ABA in the United States where she spent one month working across home, public schools, and specialist ABA settings. Sarah has also presented research at two state conferences. 

In 2017, Sarah established acornABA and now provides ABA instruction and consultancy across the UK and provides ABA training for both parents and aspiring tutors.  As a board certified behaviour analyst and a UKBA(Cert),  she also provides supervision to BCaBA’s and RBTs, those seeking supervision hours towards their BCBA, UKBA(cert) accreditations.
