ABA therapy, also known as Applied Behavior Analysis, is a treatment that uses behavior analysis to improve social behavior. ABA therapists work with clients to identify what stimuli trigger maladaptive behaviors, and create coping solutions along with teaching positive behaviors.
ABA therapy is recommended for those with autism because it addresses emotional and practical needs, grows developmental skills, and improves daily life. ABA care plans can adjust to client needs and use small steps to create significant results.
Spectrum Behavioral Therapies’ ABA programs near Fullerton offer customized care based on clients’ individual needs. What the client needs is always our main concern, which requires empathy and adaptability as each client’s needs change.

We offer a variety of ABA therapy programs near Fullerton, CA, that cater to different needs and age groups.

Families in and around Fullerton often seek ABA therapy for children and teens that integrates smoothly into daily routines at home, school, and within the community. Spectrum Behavioral Therapies supports families across Fullerton neighborhoods such as Downtown Fullerton, Sunny Hills, and Fullerton Hills, and works with children enrolled in Fullerton School District, Fullerton Joint Union High School District, and nearby schools in surrounding areas.
Our center provides comprehensive ABA services, including behavior assessments, individualized treatment plans, parent training, and social skills groups.
Each service addresses specific needs and promotes overall development.
ABA therapy for children teaches motor, social, communication, and independence skills. Our ABA therapists will encourage positive behavior patterns and provide coping mechanisms for triggering stimuli. Parents can see a change in their children with consistent sessions.
Early intervention services cater specifically to newborns and toddlers showing signs of developmental delays. The neuroplasticity, the ability to learn and change patterns, of their developing brains allows for the greatest results in a small child.
Our young adult and adult programs concentrate on breaking maladaptive behavior patterns and teaching more positive behaviors to replace them. While it might take longer than with a child, adults can see developmental growth with time.
Going to school is a significant life and routine change for students of all ages. Our program will focus on building specific skills such as focusing, listening to instructions, and social skills to ensure our clients thrive in school. We can also provide on-site support if needed.
Developing social and communication skills is difficult to do with only an ABA therapist or behavioral technician. This is why Spectrum Behavioral Therapies offers a specific program where clients can practice in a supervised environment with their peers.

It’s been a year since my kids have been with Spectrum, I can’t begin to tell you how amazing everyone at Spectrum has been with both my kids. All of their staff have done an amazing job with my two kiddos, I have seen great progress with my almost 5 year old and my 3 year old; behaviors have improved drastically from when they first started a year ago to now. Anyone looking into ABA agencies, I strongly recommend you consider Spectrum, they will be very helpful, reliable and friendly.Posted on Alexis AmbrosioTrustindex verifies that the original source of the review is Google. Spectrum has truly been life-changing for our family. From the moment we walked in, we felt welcomed, supported, and cared for. The office is always spotless and inviting, and full of people who truly care about the children they work with. Jess has been nothing short of amazing. Thanks to their patience, dedication, and skill, my son has found his voice and made progress we once only hoped for. Richie and Marisa are incredible supervisors! Always on top of everything, quick to communicate, and making sure we always feel like a priority. We’ve been to other clinics for different therapies, but nothing compares to the care, professionalism, and genuine passion we’ve experienced at Spectrum. We are beyond grateful for the difference they’ve made in our son’s life. 🤍Posted on Maria ServinTrustindex verifies that the original source of the review is Google. What can I say if my son has been with this company is for a good reason for over 5 yrs . Me as a mom can recommend them 100% in all areas from CEO, supervisors, bts and not forgetting scheduling communication is the key if you need your child to grow in all areas 😉Posted on Melanie DTrustindex verifies that the original source of the review is Google. We have been with Spectrum for almost a year now, and I truly can't say enough wonderful things about them. From the very beginning, the entire staff has been caring, patient, and genuinely invested in my son's growth. The progress he has made in such a short time is nothing short of amazing, and I know it's because of the dedication and skill of this incredible team. Special thanks to Alex, Daniel, and Kenneth, who work with my son directly and bring so much energy, compassion, and creativity to every session. They meet him where he's at, celebrate his victories, and help him through the challenges with kindness and understanding. I also want to recognize Marisa and Janet, who are outstanding supervisors--always checking in, offering guidance, and making sure every plan is tailored to fit my son's needs. What makes Spectrum stand out is that they don't just provide therapy, they become like family. We always feel supported, heard, and valued. Knowing my son is surrounded by people who truly care about him and want him to succeed means the world to us. If you're looking for an ABA center that will treat your child with respect, patience, and genuine love, I wholeheartedly recommend Spectrum. They have been a blessing to our family.Posted on maria RodriguezTrustindex verifies that the original source of the review is Google.

My child has been with Spectrum for about two years. We are very lucky and fortunate to have selected this ABA company out of many other companies to help our child learn and grow everyday. Scheduling with Anna and team is very convenient because you can either text or email them and they'll respond in a timely manner. Big shout out to Samantha, Kim J, Dalena, Kim T, Melody, Yiming, Kelsey, Cynthia, Elizabeth, and Ashley. They have been nothing but exceptional in our child's case. Very professional, kind, and great human beings. I could tell that they really care about what they're doing. They set goals and help our child meet them. I have no complaints because I have seen the progress our child has made from potty training to learning how to talk, monthly clinic meetings, and the parent training have really helped us as parents. All of the people that I have mentioned above are an important asset to this company and if you're looking for an ABA company, I wouldn't look elsewhere.Posted on Steve BeyerTrustindex verifies that the original source of the review is Google. We’ve used Spectrum now for over 3 yrs and thanks to their efforts our now 7 yr old daughter has made tremendous progress. They are well staffed with really good people that are professional and effective. It is also easy to reach them and easily communicate with their supervisors/administrative staff.Posted on Eng MengTrustindex verifies that the original source of the review is Google. SBT has been the only behavioral therapists that has worked with my son and I’m so happy that I chose them first. He has been with them for nearly 3 years and the progress that he has made has been tremendous. He has learned to speak in full sentences, ask us for something when he wants it, listens to directions, sustaining attention and so much more. At SBT, not only do they ask you what goals you want for your child but they also come up with goals that they think your child should learn. Educational goals, life skill goals, social goals, any goals that you can think of, they will come up with a plan together with you to achieve those goals. Not only do they care about your child’s progress, they also care about the parents as well. They constantly make sure to answer any questions or concerns you may have and they will try their best to fit all the sessions into your schedule. If your looking for a behavioral therapists that can teach your child anything, I highly recommend SBT!Posted on Angie KangTrustindex verifies that the original source of the review is Google. My child has autism and ADHD and was previously in a Special Day Class at a public school. During his 3rd-grade IEP meeting, I requested a 1-on-1 aide so he could attend some academic subjects in a general education class where he wouldn’t have difficulty. However, the school denied my request, and the general education teacher responded by asking me, "What would be good for you to send him to a general class?" I was shocked by this response and realized that I couldn’t send my son to a school with that kind of attitude. I found a private school that was willing to accept him, but they required an ABA therapist to be with him during school hours. The parent who recommended this school spoke very highly of the ABA therapy center her son attended. That’s how I found Spectrum Behavioral Therapy and began services with them. At the same time, my son started attending his new school with the support of behavioral therapists. From the very beginning, we met an amazing team. Andrew was the team's supervisor, and the therapists—Alyssa, Gia, Kenneth, and Jessica—worked so incredibly hard to help my son adjust to school and succeed. I cannot thank them enough for their dedication. We had experience with another ABA therapy center before, but I can confidently say that Spectrum Behavioral Therapy is on a completely different level. They go above and beyond expectations. They notice things I don’t see, suggest solutions before I even realize there’s an issue, and genuinely care about my child with such warmth and dedication. Transitioning from a Special Day Class in a public school to a general education setting in a private school was a huge challenge. The first year, which started in the second semester of 3rd grade, was especially tough for my son. Everything was new, and he struggled to adjust. He had frequent tantrums, and at one point, the school suggested homeschooling for a few weeks. We tried a hybrid schedule—two days at school and three days at home—until he was ready to attend more regularly. Andrew, along with his team of BTs, worked closely with us throughout the remainder of 3rd grade and summer break to create a solid plan for 4th grade. Thanks to their dedication and support, when 4th grade started, my son was able to attend school full-time. Of course, there are still some challenging days, but he is doing unbelievably well and continues to improve every single day. His team evolves as he progresses. Once he accomplishes certain goals, they set new ones to help him continue growing. His current team—Andrew, Janet, Patrick, Carolina, Jennifer, and Jessica—works tirelessly to support him, and I am beyond grateful for all they do. I hope my experience can help other parents who are looking for the best for their children. We all want to give our kids the support they need, and Spectrum Behavioral Therapy has truly made a difference in my son’s life.Posted on Madison PurpuraTrustindex verifies that the original source of the review is Google. We started with Spectrum last year when our nugget had to be removed from his daycare due to aggression. With not an aggressive bone in our bodies, we had not the slightest idea how to address the problem but we wanted him to be in a place that he could start kindergarten in August. Getting him started with Spectrum was easy and quick since he already had his autism diagnosis. They asked a ton of questions to make sure they were addressing every concern we had and doing it in a way we were comfortable with. They wanted to know him and immediately saw him for the bright, funny guy he is. I've never felt like he was too much when he's there. He has so much fun and never wants to leave. I'm elated to say that in less than 6 months, the aggression was gone at home and we are now struggling to think of things to work on! He's using his words effectively and keeping his emotions regulated. He's learned to play games and not get upset if he loses. He's learned to sit for longer periods of time to do table work and, in turn, has started reading and writing at a new level. He's even showing empathy and compassion for others which I never thought would be in the cards. He is beyond ready for kindergarten. I cannot thank them enough for helping us peel back the obstacles to reach our amazing kid underneath.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
