Adelyn Tan is a licensed and registered counsellor with the Singapore Association for Counselling (SAC). She is the founder of HiDolphin Counselling for Children, Youth, and Parents, a centre dedicated to supporting families through neuroscience-based approaches, play therapy, and live biofeedback assessments.

Clinical Experience
Adelyn is trained in various play therapy modalities, including Narrative Sand, Art, and Music Therapy. She connects with children and youth in creative, fun, and developmentally sensitive ways. Her work helps release bodily discomfort, especially by attuning to children’s and youths’ body sensations. She creates a safe space for them to release anger, worry, anxiety, intrusive thoughts, and behavioural challenges. Her approach supports children in exploring their inner world, expressing themselves more freely, and reconnecting with parental love.

She is a Certified Multichannel Eye Movement Integration Practitioner (CMEMIP) for trauma resolution and a Certified Brain-Switch 2.0® Practitioner, helping children and youth process trauma or unpleasant events that affect daily functioning at school or home. These tools serve as a “first-aid kit” for children, youth, and parents. She also uses HRV Biofeedback to monitor stress levels during the treatment.

Adelyn is a Certified Transactional Analysis Practitioner (TAP) for childhood issues, enabling her to offer specialised interventions tailored to individual needs. She is well-versed in Advanced Cognitive Behaviour Therapy (CBT) and Choice Theory Reality Therapy (CTRT), providing evidence-based approaches to help clients reframe their challenges and reshape their “quality world.” She is also trained in the Satir Model to strengthen family relationships and promotes mindfulness practices for holistic well-being.

With her comprehensive training and compassionate approach, Adelyn is dedicated to supporting children and families on their journey toward healing, growth, and transformation.

Adelyn supports children and youth with neurodivergent profiles, including ADHD, ASD, and dyslexia. She helps them navigate daily challenges at school and home, such as inattention, hyperactivity, impulsivity, Oppositional Defiant Disorder (ODD), emotional regulation difficulties, academic motivation, communication issues, social skill deficits, sensory processing challenges, executive functioning difficulties, and learning differences. She works closely with parents and schools as a team to support the child’s development.

Adelyn works with children, youth, and families to address gaming addiction and compulsive screen use. She focuses on the underlying emotional needs such as escapism, avoidance, or the desire to feel competent and in control that drive excessive screen time. She helps parents understand what their child is experiencing and apply effective communication and techniques to reduce screen cravings. She conducts assessments to determine whether a child’s screen use is excessive, addictive, or indicative of a gaming disorder. Together with parents, she develops a step-by-step screen health plan to support the child’s transition toward healthier habits.

Adelyn recognises that children and youth may not always identify their experiences as trauma, PTSD, or adverse childhood experiences (ACEs). She conducts assessments to identify trauma-related symptoms and helps parents understand the root causes behind school refusal, learning loss, tantrums, aggression, or sudden emotional outbursts.

Adelyn has experience supporting children with OCD symptoms such as excessive handwashing, prolonged showers, checking, counting, and harm-related fears. She understands the OCD cycle of intrusive thoughts (obsessions) and anxiety-driven behaviours (compulsions). She conducts assessments to identify root causes and recognises that OCD can be triggered or worsened by life transitions and stress. She works closely with parents and schools to support children through these transitions.

Adelyn has helped children overcome motor and verbal tics by identifying root causes and working through them step by step. She supports children with selective mutism or anxiety-related speech challenges to communicate confidently in class, group settings, and oral exams. She has experience addressing a wide range of anxiety presentations, including generalised anxiety disorder, panic attacks, exam anxiety, and social anxiety. She equips children with “first-aid” tools to manage anxiety in the moment.

Adelyn supports families navigating divorce by helping parents understand its impact on children and youth. She conducts co-parenting sessions to foster teamwork and emotional safety. She helps children and parents adjust to new environments, process separation anxiety and grief, and strengthen family dynamics.

Adelyn collaborates closely with schools to address complex issues affecting children and youth. She participates in case conferences with various agencies to ensure comprehensive support. She also provides counselling for children and youth undergoing psychiatric treatment. She also offers online counselling for those studying overseas due to family relocation.

Adelyn has facilitated mental health, behavioural, mindfulness, and emotional regulation programmes in primary and secondary schools, as well as in community settings. She has conducted caregiver mindfulness workshops for parents of children with autism and delivered talks on mindfulness and mental health to students and educators at international schools.

Creator of the “HiDolphin Brain Power©” Programme
Adelyn designed the HiDolphin Brain Power© Programme for group settings an immersive experience integrating Biofeedback assessment, Brain-Based approaches, Mindfulness, Play therapy, and a health plan.

Children learn self-help techniques rooted in clinical practice, delivered through playful, engaging activities that help them stay calm. The goal is to support them in managing distressing emotions, intrusive thoughts, and overwhelming body sensations not by memorising rules, but through meaningful transformation and expressive freedom.

These activities activate the prefrontal cortex, enhancing focus, emotional regulation, parental connection, sensory tolerance, and social understanding. The “First Aid Kit” to weather emotional storms, build resilience, boost academic motivation, and foster self-empowerment.
