Monica Cojocaru

I am an ABA therapist with over 10 years experience in this field. I strongly believe that the right form of education can make a real difference for individuals on the autism spectrum and their family's life too. Being part of their journey, to an independent and fulfilled life, is extremely rewarding for me, on both professional and personal level.  

Mission Statement

To bring science into everyday practice with an ultimate goal of enhancing the quality of life of individuals with Autism Spectrum Disorder (ASD) and other developmental disabilities. This is achieved because we provide high standard, individualised educational services and therapy programmes focused on Verbal Behaviour.

Serina Chaireti, MSc, BCBA

I have been passionate about Behaviour Analysis, since I completed BA in Psychology at Panteion University of Social and Political Sciences. Furthermore, I completed MSc in Applied Behaviour Analysis at the Tizard Centre, University of Kent. I feel grateful that I have been taught by some inspiring behaviour analysts such as Dr Robert Mellon, Dr Mecca Chiesa and Prof Peter McGill, and now I am receiving training towards my BCBA qualification, under the supervision of Dr Christos Nikopoulos.

I have experience of working with children aged 2.5-15 years old in an ABA school; carrying out home programmes and shadowing in a mainstream school; carrying out assessments; data collection; monitoring behavioural progress and contributing in behaviour support plans.


Geanina Bucuroiu BCaBA

I am a clinical psychologist, psychotherapist and a BCaBA under the supervision of Dr Christos Nikopoulos, BCBA-D. I am working in the field of ABA for 13 years with children with autism. I am very excited that in Romania more children are screened earlier and have access to behavioral intervention. My experience is with children between 1 year and 2 months and 14 years. I feel fortunate to work in this field.

Alexander Tarasov, BCaBA

I have been working with children with autism for about 14 years. I have two masters degree qualifications, MSc of Psychotherapy and Psychosocial Interventions (Iasi, Romania) and MSc in Public Health, Health Services Innovations (Maastricht, The Netherlands). As a behaviour analyst I have got experience in teaching SEN teachers, tutors and families how to implement ABA methods in working with children with autism and problem behaviours. I am able to speak English, Russian and Romanian. I have also worked in a new ABA school in UK and involved in designing school curricula for children, designing behavioural plans, training and supervising tutors.

​I have also participated as a lecturer at international conferences where I have presented results of my experimental studies: Using video modelling in toilet training of a child with autism and Effects of functional communication training plus extinction on child’s aggression.

Hasnae Ward

I have extensive experience as an ABA therapist, including program implementation, supporting children with challenging behaviours, carrying out assessments (VB MAPP and ABLLS), parent training and online supervision. I have been working with children with autism, speech delay, and developmental delay at home and school since 2009. I have worked with children aged 2 - 16. I thoroughly enjoy what I do and absolutely love being a part of successful ABA programs under Christos' supervision and guidance. 


Roxanne Dickson, MSc, MA, MBPsS

After working in this field for several years I was selected to compete a dual-masters scholarship across Europe and California.

I am in the process of applying for the BCBA exams, after also having completed my fieldwork supervision with Dr Christos Nikopoulos, BCBA-D.

I have experience applying behavioural interventions to people of all ages. My experience includes working with individuals diagnosed with ASD and cerebral palsy. Presently I supervise home-based ABA programmes in the UK, where i conduct assessments, provide team training, design programmes and support mainstream inclusion by running social skills groups.
