The Ad Astra Team

Who We Are

Alfredo Montiel, M.A., BCBA

Founder & CEO

With over 13 years in the field of ABA and a love of learning, Alfredo Montiel created and developed Ad Astra Behavior Analytic Services with the idea of blending Applied Behavior Analysis with other sciences, specifically S.T.E.M. (Science, Technology, Engineering and Mathematics). The concept of Ad Astra BAS was born many years ago when Alfredo noticed a significant disconnect in the utilization and knowledge of current technology within most ABA companies.  This is not meaning the use of the latest and greatest high tech equipment but more so in understanding how current technology trends deeply impact the individuals and families we work with. 

Although the majority of our services are based on a medical necessity, the educational concepts of S.T.E.M. also play a key role with long term individual independence and accessibility to resources. Ad Astra BAS strives to incorporate these concepts, when optimal and ethical, within its practice of behavior analysis in order to produce long term individual changes beyond tomorrow!

On his spare time, Alfredo enjoys spending time with his wife and two young daughters. He enjoys creating and building various play activities and structures for his kids and showing them how things work.

Valerie Perez, M.S., BCBA

Clinical Supervisor

Valerie's passion for ABA can be traced back to her pre-professional days. Whether as a member of a volunteer program for children in special education or as an aunt to a nephew on the spectrum, she's been intrigued by this field from the start. The reason? She likes analyzing people, understanding what makes a person click, and creating lasting behavior change.

Valerie have been in the field of Applied Behavior Analysis (ABA) for 5 years. She started as a Behavior Technician where she fell in love with the field. From there, she moved on to a supervisory role where she was in charge of client programming and parent training. Valerie went on to obtain a Master's in ABA and hopes to become a Board Certified Behavior Analyst in the near future.

Outside of the office, she enjoys getting lost in a great book and labels herself, a bad, but enthusiastic calligrapher. She's fluent in Spanish, but loves to dabble in other languages. She's an unashamed Disney adult with a vast knowledge of all things Disney. Valerie's a sucker for punny jokes, so she'll leave you with her favorite--Does the name Pavlov ring a bell?

Ana Arnautalic, M.Ed., BCBA

Clinical Supervisor

Her enthusiasm and drive to succeed as a Board Certified Behavior Analyst (BCBA) have been influenced by experiences over the last eight years of her life. In 2013, her son was diagnosed with autism spectrum disorder and she became determined to help him in every way imaginable. Researching the available literature, becoming involved within the autism community, and networking with the large number of supportive parents with special needs children, she was fascinated by the importance and the power of early intervention. ABA therapy has greatly helped her child discover his individual gifts and talents, and is continuously helping him reach his full potential. It also provided her with an aspiration to learn more. In 2016 she enrolled in a master’s program at Arizona State University to obtain a degree in special education with an emphasis in applied behavior analysis and in 2020, she became a BCBA. Her ultimate goal is to make meaningful changes not only in the clients that we serve, but their families as well.

As a BCBA, she has worked with clients from infancy through adulthood. In the last 5 years, working in the field of ABA, she has participated in many different roles such as a registered behavior technician (RBT) providing individualized 1:1 therapy, social skills leader for preschool and elementary school-aged clients in the clinical setting, program supervisor, and behavior analyst in both home and school settings.

As relationships are very important to her, she finds a good life-work balance by spending time with her family and friends. On the other hand, photography is her artistic output that allows her to express her creative side and she enjoys capturing beautiful images of the things she loves - family, animals, and nature
