How we work:

Individual and needs-oriented

In our work we are guided by the individual needs of the clients, because every client has different needs. Based on these needs, the therapy goals are defined. We are flexible and remain attentive to adapt our therapy goals at any time according to the needs of the client.


In our ethics as educators, psychologists and as behaviour analysts we follow professional guidelines.


We consider every client to be unique and every client has the right to be perceived as unique.


Together we can do more! That is why we work together with parents, teachers, other service providers and all our clients' relatives. Only this way enables our clients to have an optimal learning environment.


We have made it our mission to promote lifelong learning by striving for quality. We define quality as adherence to scientific knowledge and high ethical standards in the educational process, without losing our empathetic focus on the client. The staff at Ausblick Therapie GmbH achieve their goals through a multi-dimensional problem-solving process and data analysis that requires self-reflective practice, collaboration, creativity and openness. Our staff learn from both successes and mistakes, which we define as the courage to go beyond our current comfort zone of what we know and are good at.


Zu unseren Zielen gehört es nicht, die Klienten zu verändern. Wir schätzen und akzeptieren unsere Klienten so wie sie sind. Gleichzeitig wissen wir um die Barrieren, die das „dabei sein“ in einer neurotypischen Gesellschaft erschweren. Wir bauen gemeinsam die Brücken auf, damit die Klienten so gut wie möglich in allen Bereichen der Gesellschaft mitwirken können.

Veneta Dimitrova, MA, BCBA

Founder and Steward

Veneta Dimitrova is a behavior analyst in recovery who wrestles herself over the edges of what she knows, she thinks she knows, and she will never know. Two decades of direct work with survivors of domestic violence and human traffic, elementary schoolers, individuals with autism and their families, obliged her to begin unlearning things she learned in the ivy-league towers of objective truth. She attempts to balance her competence with curiosity, her expertise with awe, her sharp-edges with parasympathetic calm. Her teachers include children who could conjure up a behavioral storm, mothers who have forgotten sleep, willow trees, love and grief. Since Veneta established Teaching Tree in 2014, the American US-Military families’ access to ABA services has increased by 1900%. Veneta wonders what would the quality of her work be if she integrates science with heart and strives to model and evoke playful, curious and authentic responses to the world. Veneta finds intriguing the fact that indigenous cultures rarely have a word for disability. She strives to see the human beings behind the colonial, neoliberal or DSM-5 labels they have been given. She has many unanswered questions and is clumsy at showing compassion. Instead of trying to fix problems or people, she tries to develop new ways of understanding, shedding old futile patters of behaviors, and embracing more useful perspectives. Veneta is devoted to the type of learning that breaks her open, that threatens her rigid identity, and makes more room for otherness.

By chance, she came across a posting for RBT positions, and she never looked back! In her time in the field, she has worked in both Georgia and Florida, with children as young as 18 months and as old as 19 years. After graduating from Ball State University with her Master of Arts in ABA and becoming a BCBA, she was excited to transition into a role that allowed her to mentor others in their journey to become practitioners.

Stephen Buckley, MS, BCBA

Behavior Analyst

Stephen hails from Ireland, and it is there that for many years he lived alongside the children, teenagers, and adults with disabilities with whom he worked as a carer. He found that the people he worked with grew and became happier when they experienced encouragement from carers who showed interest, compassion, and empathy for them. However, he eventually noticed that many of people he worked with also appeared to be “stuck.” Over the years, they did not significantly expand their activities, access to educational opportunities, social circles, or self-help skills. Indeed, they would even regress, like by engaging in self-harm behaviours. After researching therapies that offered to increase the self-help and social skills of people with disabilities, Stephen learned of a scientifically validated method proven successful with all types of individuals to improve all types of socially significant behaviour. In 2015, he returned to school to obtain a second master’s degree, this time in Applied Behaviour Analysis. As a trainee, Stephen introduced ABA-based strategies to a large residential centre in Ireland that had come under scrutiny for poor practices, cultivating a culture of Positive Behavioural Support. Since then, his practice has centered on consulting with German families with infants and children with autism. Stephen speaks native English and some German
