Not sure if your child might have ADHD?

ADHD makes it harder for someone to focus, sit still, or think before acting. If your child’s teacher has recently shared concerns about their behaviour, or if you’ve noticed possible signs of ADHD yourself, here are some common symptoms to look out for:

Inattentive type: Difficulty paying attention, staying organized, or following through with tasks.
Hyperactive-impulsive type: High level of activity, talks a lot, acts without thinking, or has trouble waiting for their turn.
Combined type: Symptoms of both inattention and hyperactive-impulsive. This is the most common type of ADHD.

ADHD isn’t laziness or bad behavior; it results from brain differences that affect focus and self-control. With the right help and routines, children with ADHD can develop the skills they need to succeed.

We’re here to help.

Supporting children with ADHD

Why We Focus on ABA

At Tesserae, we specialize in using Applied Behaviour Analysis (ABA) for children with Attention Deficit Hyperactivity Disorder (ADHD). ABA can be highly effective for children with ADHD as it:

Teaches important life and learning skills through structured, consistent strategies.
Uses positive reinforcement to help children improve focus, self-control, and organization.
Provides the clear structure and routine that kids with ADHD need to succeed, with each plan personalized and progress carefully tracked to ensure lasting results.

Why Families Choose Tesserae
for ADHD Support

Through our 1-1 sessions with children, we always aim to

Create Real Reasons to Communicate

We build moments that make your child want to talk. Whether it’s to ask for a toy, share excitement, or tell you what they need. Communication should come from motivation and meaning, not just repetition.

Replace Frustration with Expression

When your child struggles to express themselves, we teach practical ways to ask for help, take a break, or get attention – reducing meltdowns and helping them feel understood.

Make Learning Fun and Rewarding

Every child learns best when they’re having fun. We figure out what truly motivates your child and use it to make communication enjoyable and something they’re excited to do.

Build Skills That Show Up Everywhere

What your child learns in therapy shouldn’t stay there. We help them use new communication skills naturally, at home, in school, and out in the community, so progress feels real and lasting.

Strengthen Social Connections

We help your child learn how to look, listen, and share attention – the building blocks for connection, friendship, and joy in being with others.

Teach Through Everyday Moments

Instead of drills, we teach through play, routines, and meaningful daily activities – helping your child communicate in the real world, in their own way.

Why Trust Us with Your Child

1. Clinical Excellence Led by Southeast Asia’s Only BCBA-D

Your child’s programme is guided by Dr. Dominic Leong, Southeast Asia’s only practicing Board Certified Behaviour Analyst – Doctoral level (BCBA-D).

This ensures your child receives support that is both innovative and grounded in the latest evidence-based research. Dr. Dominic is also trained in counselling, and integrates his background to deliver a holistic, learner-centred approach to behavioural intervention.

2. Integrated Care: Collaboration, Not Just Coordination

We understand that being the go-between for different professionals and intervention disciplines can be exhausting.

We advocate for transdisciplinary care and work with your existing team (e.g., Speech Therapy, Occupational Therapy, Educational Psychology) to ensure that every session and every goal is united and effective, meaning less stress for you.

3. Secure Spaces Optimised for both Indoor and Outdoor Learning

We are fortunate to be based at The Yards, a secure, gated former primary school that has been transformed into a vibrant hub for education providers.

Surrounded by wide open fields and lush greenery, our space offers safe and flexible learning environments, with both structured indoor sessions and outdoor activities that support sensory regulation, exploration, and movement.

4. Progress That Travels Beyond Tesserae

Our commitment is to extend care beyond the therapy room, equipping you, your child’s teachers, and other caregivers with the knowledge and confidence to support growth sustainably beyond Tesserae.

How We Kickstart Support for Your Child

Our focus is on delivering progressive, evidence-based care tailored to your family’s daily life. Whether your child is just starting their journey or needs advanced support, we can offer guidance.

Screening & Consultation: Sometimes, you just need an expert opinion to start. Our screening process is a straightforward first step to understanding your child’s needs and determining the right next move.
Collaborative ABA Therapy: Our sessions aim to teach crucial skills, like communication, social interaction, and self-management, in ways that are meaningful and enjoyable for your child.
School Readiness & Shadowing: Is school integration the next big milestone? We offer specialised programmes and school shadowing to help your child successfully transition into a mainstream or special education setting with confidence.
Enrichment Programmes: We pioneer creative models of care, integrating movement, dance, and social skills training. Learning shouldn’t be rigid; it should connect to your child’s personal interests.

Testimonials

What Parents and Partners Say About Us

I would like to thank Teacher Dominic for the guidance and support he has shown to Ian. Ian has made tremendous progress over the past year with him, especially in social skills and communication.

What I appreciate most about his approach is his ability to work collaboratively with our family’s needs.

He took the time to understand our goals and concerns, and consistently provided us with feedback and strategies to support Ian’s progress. His assistance in helping Ian learn how to queue and wait nicely is just one example.

Thank you for the great work he has done with Ian. Although we are putting a stop to the therapy sessions due to other commitments, we look forward to seeing him again in the upcoming social classes.

Stephanie was our autistic son Jason Kan's teacher and behavioral consultant for over three years. As a behavioral consultant, Stephanie would not only teach Jason, but would also help organize Jason's behavioral intervention sessions and manage other teachers working with him.

Our son loved Stephanie and we loved how open and transparent she was with explaining how sessions with Jason went. We would highly recommend Stephanie.

Finally, we wanted to inform how Stephanie is a wonderful and trustworthy professional. She deeply cares for children and is deeply passionate about bettering the lives of special needs children. Thank you for taking the time to read our testimonial.

I am truly grateful for the social skills program led by Teacher Dominic. Through the sessions, my child has learned how to talk nicely to others, take turns in conversations, and express thoughts in a more considerate and confident way.

What impressed me most was how the lessons went beyond simple social rules. They helped my child understand tone, body language, and how to adjust responses based on different situations. These are advanced conversational skills that have made a real difference in how my child interacts with peers and adults.

I have seen growth in his ability to join group discussions, maintain conversations, and show awareness of how his words can affect others

The (ABA) Dance Program has been an excellent experience for my child. The sessions are engaging and enjoyable, and I have seen improvements in his confidence and social interactions. The instructors are patient and skilled at balancing fun with teaching. My son looks forward to every class, and as a parent, I appreciate how this program brings together movement, communication, and relationship building through the joy of dance.

We are so grateful to Dr Dominic Leong for leading a musical theatre class at Sing’theatre Academy for children with autism. He brought a great deal of patience, care, and professionalism, making the children feel truly included and engaged. Some children exceeded our expectations after going through the class!

Beyond the class, our teachers also learnt so much from him, and we still use his techniques today. His guidance has helped us open more doors to make the joy of the arts accessible to every child!
