The kind of ABA we’d want for our own children.

Contact Us

At ABA Behavior Services, we believe every child deserves exceptional care. As a privately owned, doctoral-level practice, we provide high-quality individualized Applied Behavior Analysis (ABA) therapy for children with autism, ADHD, and behavioral challenges. Our approach combines evidence-based practices with modern, neurodiversity-affirming, assent-informed care. Through play-based learning, natural environment teaching (NET), and structured instruction when appropriate, we tailor our approach to each child’s unique strengths, needs, and goals.

What sets us apart is our personal involvement and the genuine relationships we build with families. From your very first phone call, you’ll speak directly with our owner and executive director, Dr. Alexandra O’Grady, PhD, BCBA-D—not an intake coordinator. With over 15 years of experience, Dr. O’Grady remains personally involved in every case, working closely with our clinical team to ensure exceptional care. We consider it a privilege to be part of each child’s life, and many families remain connected with us long after services end.

Based in Berkeley Heights, New Jersey, we provide home-based, school-based, daycare, preschool, camp, and community-based ABA therapy throughout Northern and Central New Jersey, including Westfield, Summit, Chatham, Madison, Short Hills, New Providence, Scotch Plains, and surrounding communities.

Through individualized ABA therapy, clinical supervision, caregiver training, and meaningful collaboration, we focus on building lasting skills, increasing independence, and helping children thrive in everyday environments. Our goal isn’t to provide more therapy than a child needs—it’s to provide the right support, at the right time, for meaningful and lasting progress.

We’re excited to expand our services with a new center-based ABA therapy location in Westfield, NJ, opening January 2027!

  • 2026 CLINICAL OUTCOMES: 100%

    Successful School Integration

    6 Out of 6 Children

  • The Impact of Individualized ABA Therapy

    Of the six children who began ABA services with us between ages 2 and 3 due to significant behavioral challenges interfering with daycare or preschool participation or maintained placement, all six successfully transitioned into inclusion or general education Kindergarten classrooms in public or private school settings.

  • The right ABA therapy should build skills that last...

    …Not create unnecessary dependence on services.

    Through individualized ABA therapy, targeted skill development, caregiver training, and collaboration with educational teams, we helped these children build the skills necessary for greater independence and successful participation in their learning environments. No child has time to waste, so we focus on building independence and systematically fading support as soon as appropriate.

  • “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… 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.”

  • “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 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.”

“Our philosophy is simple: to provide compassionate and effective ABA services just as we would for our own children.”

About Us

  • "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. As a parent and a special education advocate I can say 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."

  • “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. 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.”

  • “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 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.”

  • “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.”

  • "When my child was diagnosed with ASD later on than most I knew I needed to find him services right away. I called place after place. I either received no call back, was turned away or promised help and was ghosted. From the second I spoke to Dr. O’Grady it was an instant relief. Everything that I’ve experienced working with her and all the therapists and especially our BCBA have been beyond positive. Anyone I’ve referred to them thanks me! I have been in education for 20 years as a teacher and know the good, bad and ugly. ABA Behavior Services is the exceptional!"
