About Us
Smilestones (Cambodia) Co., Ltd. was established in March 2019 in response to a pressing need for high-quality, autism-related services in Phnom Penh.
We provide evidence-based, international-standard therapy for children with developmental needs, including Speech Therapy, Occupational Therapy, and ABA. Our approach is transparent, integrated, and family-focused—delivered in a variety of settings including in-home, in-school, and at our centrally located therapy centre in Rose Condo, Tonle Bassac.
At Smilestones, we believe that when children are supported across all environments—with parents, teachers, and therapists working as a team—they thrive. Our mission is simple: to help every child reach meaningful milestones in a way that feels natural, joyful, and lasting.
Mythili Chengapa
Founder & CEO
Mythili Chengapa is a devoted mother and early childhood development advocate. Her experience managing an international kindergarten in Phnom Penh revealed a serious lack of trusted, high-quality autism support services in Cambodia.
In response, she founded Smilestones in 2019, bringing together top internationally qualified therapists she personally trusts. Mythili remains actively involved in every case to ensure families receive the kind of care she wishes had been available earlier in her career. Her dedication drives Smilestones to provide transparent, evidence-based, and family-centered therapy that truly makes a difference.
Having lived in Cambodia for over 12 years, I’ve developed a deep connection with the people, the culture, and the language. I’m immensely grateful for the opportunities this country has given me, and I feel truly honored to be able to give back by offering much-needed support to families—especially in their own language.
At Smilestones, our mission is to help families improve their quality of life through effective strategies. We offer Speech Therapy integrating ABA principles, have started providing Occupational Therapy too and are actively providing the latest developments in Augmentative and Alternative Communication (AAC), to ensure that every child has a way to express themselves meaningfully.
We believe in supporting each child’s communication journey in whatever way works best for them and most importantly by staying updated.
Over the past six years, I’ve led the development of training programs and awareness campaigns in both Khmer and English. These initiatives aim to promote inclusivity and understanding, reaching even the grassroots of Cambodian society.
Driven by the ever-evolving needs of the children we serve, my team and I are constantly researching and implementing effective regulation strategies and expanding our offerings. I’m incredibly proud of how far we’ve come—and even more excited about the road ahead. One step at a time, one smile at a time.
