About Us
Exceptional ABA Therapy. Individually Designed for Your Child.
At ABA Behavior Services, we believe every child deserves exceptional, individualized care. As a privately owned, PhD-level, BCBA-D led practice, we combine advanced clinical expertise with a compassionate, neurodiversity-affirming, assent-informed approach to ABA therapy.
We specialize in supporting children with autism, ADHD, and behavioral challenges through individualized, evidence-based interventions that incorporate play-based learning, natural environment teaching (NET), and structured instruction when appropriate. Our approach is tailored to each child’s unique strengths, needs, and individuality.
Our goal isn’t simply to provide therapy. It’s to build meaningful skills, foster independence, and create lasting positive changes that extend far beyond our sessions.
At ABA Behavior Services we are a New Jersey Department of Education (NJDOE) approved agency. We provide the highest quality ABA therapy to toddlers, children, adolescents, and young adults of typical development and who are diagnosed with Autism, ADHD, ODD, and Related Disorders in the NJ area.
Founded by Dr. Alexandra O’Grady, ABA Behavior Services was built on a simple belief: every child deserves thoughtful, individualized care, and every family deserves to feel genuinely supported.
Our team combines clinical expertise with a collaborative, relationship-based approach that prioritizes meaningful progress and lasting independence.
Dr. O’Grady takes a hands-on, collaborative approach to clinical leadership and remains personally involved in every case ABA Behavior Services takes on. Families speak directly with her from their very first phone call and continue to benefit from her experience, guidance, and clinical oversight throughout their child’s care.
With over 15 years of experience, she works closely with our team to ensure every child receives individualized, evidence-based treatment that reflects the same standards of care she would want for her own children.
Our dedicated team is made up of high-quality professionals including Doctoral-Level Board Certified Behavior Analysts (BCBA-Ds), Board Certified Behavior Analysts (BCBAs), Registered Behavior Technicians (RBTs),
and Behavior Therapists.

Hear More From Our Families
“We are forever grateful to ABA Behavior Services and Dr. Alexandra O’Grady for the life-changing impact she and her team have had on our son and our family. For three years, Dr. Alex and her staff provided in-home ABA services to our son, who has profound autism and is nonverbal. Their compassion, patience, and expertise truly changed his life. Although he cannot speak, he learned to communicate using an AAC device thanks to Dr. Alex and his therapist Michelle, a breakthrough that transformed how he connects with the world around him. They helped him develop skills he can use both at school and at home and created routines that made him feel safe, comfortable, and confident. Most importantly, they helped our son learn how to exist and thrive in a world that is not always designed for him. In addition to being a parent, I also owned a special education advocacy firm and later had the opportunity to work alongside Dr. Alex on other cases. Through that professional experience, I witnessed firsthand the exceptional care she provides to every child she serves. She goes far beyond therapy, attending school meetings, preparing thorough reports, collecting meaningful data, and advocating tirelessly to ensure children receive the support they deserve. From both a personal and professional perspective, ABA Behavior Services sets the standard for compassionate, ethical, and truly effective care. Dr. Alex and her team change lives, and we will always be grateful for the support they provided to our son and to so many other families.” - Parent of Former Client, Chester
“I had an excellent experience collaborating with Alex, Jen, and Alina at ABA Behavior Services. Jen, the BCBA, demonstrated exceptional thoroughness and attentiveness, carefully listening to our stories, concerns, and goals. She crafted personalized plans tailored to my son's individual needs. Alina was a pleasure to work with, bringing a calm, encouraging, and experienced approach. My son had a positive experience with her, feeling comfortable around both Alina and Jen. Their support has been invaluable in helping my son navigate his initial experiences in a private school setting.” - Parent of Former Client, Chatham
“We worked with Dr. Alex O’Grady and her team, and the quality of care you receive here is truly unmatched. The therapists and BCBAs are experienced, compassionate, and incredibly attentive — you can immediately tell this is not a corporate, franchise-style ABA company where kids feel like numbers. We previously had experiences with large in-network companies, and the difference was night and day. At ABA Behavior Services, our child was treated as an individual. You can see and feel that your child genuinely matters. Dr. O’Grady has a PhD in Applied Behavior Analysis from one of the only accredited programs of its kind, and her expertise shows in everything she does. She holds her team to an exceptionally high standard and ensures every child receives the same level of care she would want for her own children. If you’re looking for high-quality, ethical, individualized ABA services (and the same therapists, not a new therapist every month) and not just your run of the mill ABA company — this is where you’ll find it. I can’t recommend them enough.” - Parent of Former Client, Westfield
“We feel very fortunate that our daughter received services through ABA Behavior Services. From the first phone call with Dr. O’Grady (Alex) we felt relieved, supported, and heard. Alex worked hard to find a consistent team that was experienced with children that share a similar profile to our daughter to expedite her progress. Sarah, the therapist, built a lifelong rapport with our daughter that we never imagined was possible. Alex delivered on her promise of providing the type of services she would want her own children to receive. We are thankful that our daughter now has the foundational skills to be successful without additional support.” -Parent of Former Client, Summit
“We had a wonderful experience with ABA Behavior Services. Our son worked with incredible therapists who provided highly personalized support, helping him build confidence and improve his interactions with peers. Alex and the BCBA, along with the therapists, were always open to our input, making adjustments as needed to ensure the best possible experience. We truly appreciated the thoughtful, compassionate, and professional care he received. I highly recommend them to any family seeking individualized support.” - Parent of Former Client, Morris Plains
“ABA Behavior Services completely changed our lives. Our daughter went from unable to sit still and constantly dysregulated at 2, to a glowing, social, emotionally regulated, academically advanced and mainstreamed kindergartener at 5. Alex and Rachel expertly designed her plan to address all of our goals and ensure our daughter was happily supported throughout her 2s, 3s and pre-K. The warm and wonderful RBTs including Pam, Michelle, and others, instantly bonded with our daughter and were there for her whenever she needed comfort or assistance, without interfering with the classroom lessons or forming excessive reliance on others. We could never have imagined our child would be where she is now. Her incredible neurodivergent-affirming team at ABA Behavior Services gave her the tools she needed to learn how to self-regulate and advocate for herself so that she can succeed in any environment. We are eternally grateful.”- Parent of a Former Client, Westfield
