Shaina Tonge, M.Ed, BCBA

Board Certified Behavior Analyst

A profession in Applied Behavior Analysis (ABA) seemed almost destined for Shaina. From a young age, Shaina’s interests were piqued in learning about the human mind and how it translated into behavior. Peeking at her mother's college psychology textbooks and observing people and their interactions with the world around them, her interest continued to be cultivated. This led to Shaina pursuing her own undergraduate degree in Psychology at the University of California at Berkeley.

After graduation, Shaina began her journey into the field of ABA, which combined her interest and experience working with kids, teens, and young adults, as a Behavior Technician. In this role, she found her inspiration to learn more and make a positive difference, leading her to obtain a Master's in Education, with a focus on ABA curriculum and instruction from Arizona State University. Years of experience and the support of mentors and peers led her to ultimately become a Board Certified Behavior Analyst in 2017. All these years later, she is just as motivated to learn, grow her skills, and ensure she is following the best evidence-based and ethical practices. 

Shaina's experience with ABA includes working with individuals between the ages of 2 to 22 years old with various levels of support needs, their caregivers, and other services providers. She has conducted her work in a variety of settings including homes, schools, camps, and in the community. Her strengths include implementing neurodivergent affirming teaching and support for increased communication, independence, social skills, and self-advocacy.

Outside of behavior and ABA, Shaina enjoys spending time with her daughter, husband, and two cats; gardening; spending time in nature; and exploring new interests and potential hobbies.

Guofeng Shen, M.A., BCBA

Board Certified Behavior Analyst

Guofeng received her master’s degree in Early Childhood Special Education in 2018 from University of Northern Colorado (UNC) and taught in the public school system in a variety of settings. While working as a special education teacher, it became apparent that challenging behavior is one of the biggest issues for students with and without disabilities. It was especially evident in students with autism. How to engage students in lessons and how to manage students' challenging behavior are keys for successful teaching and learning. Applied Behavior Analysis (ABA) is the science that provides the guidance for solving this issue. Thus, the next and present stage was to enter the special education Ph.D. program with an emphasis on ABA. Currently she is in the final stages of her Ph.D. program. 

Guofeng’s working experiences with individuals of autism, other developmental disabilities, and families from diverse backgrounds spans more than 5 years. Her professional experience includes but not limited to the following: as an Early Childhood Special Education Teacher in the public school system. Worked as a behavior therapist and trainer in the clinic and home settings. Further, worked as instructor and co-instructor for multiple ABA undergraduate and graduate courses. She also has conducted research and has published peer reviewed journal articles in the area of behavior analysis and special education. In addition, Guofeng has presented at national and international conferences on topics associated with ABA, as well as ABA trainings for families and teachers.
