Serving You

Behavior consultation is a problem-solving, empirically driven process in which a Behavior Analyst identifies and tracks progress on behavioral goals (whether reducing disruptive behavior or teaching new skills). They develop and implement interventions designed to bring about meaningful change on those goals. The effect of these interventions is continuously assessed through direct data they collect, and the interventions are changed or kept based on their proven success. This continues with the purpose of improving clients’ lives through goal achievement.
A behavior assessment is a process through which a Behavior Analyst identifies the specific variables that cause an individual to behave a certain way. This allows the Behavior Analyst to develop an effective treatment plan. The main components of an FBA are typically: systematic direct observation, indirect assessment (questionnaires and interviews), and functional analysis (controlled experiments to determine which variables tend to increase or decrease the behavior).
Boulder Analysts is committed to bringing long-term success to our clients. This involves not only implementing effective plans ourselves, but teaching those that live with our clients every day to implement effective strategies to ensure that adaptive behavior remains long after we have gone.

J.J. Tomash
J.J. Tomash, Ph.D., BCBA-D, Owner

J.J. Tomash has studied and applied Behavior Analysis for over 16 years. He spent his educational career, from his Associate’s degree through his Ph.D. at Swansea University, studying the Science of Behavior, and how it can be applied to solving real problems. He spoke at several international conferences, published multiple articles in peer-reviewed journals, and received research awards. Following his studies, and a brief interlude living in India, Dr. Tomash turned to the practical application of Behavior Analysis. He acquired his BCBA working with Josh Pritchard at Lodestone Academy. He has had the good fortune to work with a wide variety of individuals and needs- conducting functional analysis and assessments, designing and implementing interventions to reduce disruptive behaviors; teaching communication, social skills, and independent living skills. He has worked in virtually every setting where clients need help.
Throughout his academic and practical studies of behavior analysis, Dr. Tomash has acquired a deep respect for Behavior Analysis as a great tool to improve people’s lives. Its power goes far beyond reducing particular problem behaviors, but to finding and teaching the targeted skills that will make problem behavior unnecessary.

Nicole Da Lima Leitao, M.Sc., BCBA
Clinical Director

Growing up in India, Nicole saw first-hand the need for research-based services for those with developmental disabilities and in the field of mental health. This brought her to the UK, where she completed her M.Sc. in Abnormal and Clinical Psychology. She returned to India and worked in a care center with adults with intellectual disabilities.

In 2013, Nicole moved to Orlando, FL to pursue her Board Certification as a Behavior Analyst. In Orlando, she she worked in one of the first behavior analytic schools in the area: Lodestone Academy. Here she worked with children ranging from ages of 3 – 23 years, a wide variety of behavior problems and needs, and a close-knit group of highly trained Behavior Analysts. She acquired experience developing and conducting a variety of programs, assessments and curriculum-based trainings.

Nicole’s love for the mountains, as well as her determination to bring Behavior Analysis to new areas of need, drew her to Colorado in 2015. She worked with another large company in the area until May, 2016- when she became the Clinical Director at Boulder Analysts.
