Team Triangle ABA

Our caring and collaborative team provides a supportive work environment conducive to helping enrich the lives of children and their families.

Owner, Founder, CEO: Amber Nelms, BCBA

Amber Nelms is a board-certified behavioral analyst, who has synthesized her educational foundation in behavioral science with in-field experience and personal insight. As a mother of a child with autism, Amber knows what it is like to be on both sides of the equation when teaching and learning how to parent an individual diagnosed with Autism Spectrum Disorder (ASD).


Max Baenen, MA, BCBA: Clinical Director

Max is a BCBA. He has been in the field of Applied Behavior Analysis for 7 years.

He started out working in an academic setting as a teacher for high schoolers on the Autism Spectrum. From there he began to work 1:1 with young adults working on functional life skills and vocational goals. He also has experience working as a clinical supervisor for clients diagnosed with Oppositional Defiant Disorder and Emotional Disturbances. More recently, he has worked closely with families in a home setting to train caregivers and develop programs that can be applied naturalistically in a home setting.

Max received his Masters in Applied Behavior Analysis with a focus on Autism from Ball State University. He completed his undergrad in Psychology at The Ohio State University.

Max has been working with children his entire adult life. His inspiration for pursuing a career helping children stemmed from being an older brother. In high school he interned in an Early Childhood Professions program, since then he has been a teacher at a Montessori school, an after school coordinator, a classroom aide, a teacher for clients with special needs, a classroom coordinator, a clinical supervisor, and a BCBA. Through these experiences, he has developed a skill set that not only focuses on socially significant clinical outcomes, but also developing connections with families and educators alike.

Outside of work, Max enjoys spending time disc golfing. Additionally, he enjoys playing music. He enjoys going on hikes with his wife, Mari, their daughter, and their two dogs- Nikko and Murphy. 

As part of the leadership team at Triangle ABA, Max utilizes his talents to focus on program development, team building, and clinical excellence in collaboration with Amber Nelms and the rest of the clinic.

Joshua Ginsburg, BCBA, Technical Advisor

My name is Josh, and I’m excited to be here! I’ve been a BCBA for over 7 years and in the field of Applied Behavioral Analysis for even longer! 

Over my time in the field, I’ve worked with clients in a large variety of settings including in both public and private schools, in home, in community, and in clinics. I’ve also worked across age ranges as well, from as young as 2 to as old as 18, and have taught and created programs to teach skills that benefit all types of learners, from those just learning to communicate to those beginning to develop a functional vocabulary to teaching leisure and work skills to engage with as an adult. I’m also experienced in both skill acquisition targets as well as reducing or decreasing maladaptive behaviors. I strive to focus on effective, ethical, and socially relevant programming, and a key focus for me is to ensure that anything we can accomplish at the clinic generalizes to the home and community environment as well.

While I only started at Triangle recently, I’m excited to be here and happy to be part of the team!

Hadeel Khrais, BCBA

My name is Hadeel Khrais and I’m a Board Certified Behavior Analyst (BCBA). Prior to becoming a BCBA, I was a public school teacher for 10 years. I have worked with children with disabilities for the past 17 years in different capacities. I started working as a CAP worker for several years, prior to becoming a general education/special education teacher. I have worked with children with a wide range of disabilities: autism, learning disabilities, down syndrome, ADHD, etc. ages 2-10. In 2016, I taught a self-contained autism classroom and implemented ABA principles. I fell in love with ABA and decided to pursue my BCBA certification. I worked as an RBT (research behavior technician) for two years while studying to become a BCBA. I obtained my certification in May 2021.  

Prior to working at Triangle ABA, I worked at other ABA clinics that offered services in the home and clinic settings. I have worked with ages 2-11 with autism and other developmental disabilities. I was also a social skills instructor providing techniques and strategies to help adolescents with autism create and build meaningful friendships. 


I have worked at Triangle ABA for several months and I love my co-workers and BCBA. I’m excited to continue to work with an amazing team and learn and grow here at Triangle ABA!
