Working with children with autism and their families across the past 10 years has been the most fulfilling part of my life. I started in this field as a paraeducator and instantly fell in love because I could see the tremendous impact I was making in each child’s life every day. That experience inspired me to pursue my certification as a behavior analyst in order to expand the extent of my impact on the field. I began as a special education teacher in Washington State, and then moved into the private sector as a clinician after moving to Arizona. My goal every day is to improve the lives of individuals with autism and their families through effective, comprehensive programming to address their needs.

I began my degree shortly after starting work at Trumpet Behavioral Health. From the first few days at Trumpet, I began learning about autism and Applied Behavior Analysis, and this has not yet slowed. I look forward to every day at Trumpet to see the changes in client’s behaviors and to learn new things!

Philosophy of Care

I love providing therapy to children with autism because this is a field in which you can truly make a difference, and you can see the difference that is being made from day to day. Not only that, but the changes that are being made are done using positive reinforcement!

I have been working with individuals with special needs for over 10 years. I immediately fell in love with helping kids and their families and later fell in love with the science of Applied Behavior Analysis. Since then, I have worked providing in-home ABA therapy, school district consultation, and charter school administration.


MA in Teaching/ABA, National University, 2011
BA in Psychology, University of Nevada, Las Vegas, 2008

Philosophy of Care

I feel very fortunate to have found a career as fulfilling as helping children with special needs and their families. After working at day cares and summer camps for years I learned how much I love interacting with children. I knew I wanted to help children, but it wasn’t until I learned about ABA that I knew I had found my career. I approach every new challenge in a person-focused manner using best practices. I have been very lucky to work with many caring and loving mentors and am honored to collaborate with so many brilliant minds. I have implemented what skills I’ve acquired in many settings including: school paraprofessional, behavior therapist, school administrator, school district consultant, and early intervention specialist.

I started working with developmentally disabled children after taking a part-time job working in an autism clinic. I immediately knew that this was a career path I would enjoy and shortly after, I began pursuing my master’s in Applied Behavior Analysis. I have worked with children and adolescents from 2 years of age up to 12 and love learning new techniques and procedures to provide for these clients.


MA in Applied Behavior Analysis, Ball State University, 2015
BA in Business & Non-Profit Management, Earlham College, 2010

Philosophy of Care

The best part about this line of work is witnessing the progress the children make during our time with us and the transformation that the progress has on the family as a whole. I have seen the outlook of a mother or a father go from bleak to excited after only a few weeks of ABA services. That is what makes this job so great.
