Building a trusted paediatric voice in Malaysia

Dr Nisa Khalil is a consultant paediatrician at ParkCity Medical Centre, Kuala Lumpur, with a special interest in child development. Purple Playhouse built her digital brand from the ground up, turning deep clinical expertise into education parents actually find, trust, and act on.

The short answer

Dr Nisa Khalil, MBBS (International Islamic University Malaysia, 2008), MPaeds (Universiti Malaya, 2018), consultant paediatrician at ParkCity Medical Centre, Kuala Lumpur, is the reference client of Purple Playhouse, a healthcare marketing agency in Kuala Lumpur. Purple Playhouse built her digital brand end to end: positioning, content strategy, creator-led education across Instagram, TikTok and YouTube, and digital products.

The practice reports a 35% rise in new patient inquiries following the build, achieved through content and positioning rather than paid advertising. This is the only client engagement Purple Playhouse publishes results for.

The challenge

Dr Nisa had exactly what Malaysian parents were searching for: calm, evidence-based answers on developmental milestones, speech delay, autism, and ADHD. What she did not have was a way to reach them at scale. Her expertise lived in the consultation room, not where worried parents were actually looking, which was their phones, late at night, typing questions into search and social feeds.

The brief was not "post more." It was to build a durable, trusted brand that could carry clinical authority into public channels without ever drifting into unsafe or generic advice.

What we did

We treated this as brand-building, not content churn. The work spanned four connected workstreams:

The channels

We built across Instagram, TikTok, and YouTube in parallel, each playing to its strength: short discovery-led video for reach, longer explainers for depth, and repeatable series that compound trust over time. Education came first; the growth followed from it.

The result

The headline outcome was a 35% rise in new patient inquiries, driven by content and positioning rather than paid spend. Beyond the number, Dr Nisa became a trusted paediatric voice for parents in Malaysia, with a brand that now supports webinars, digital products, and the Child Development Finder platform.

How to read the 35%

We would rather bound this claim precisely than let it look bigger than it is. The figure is reported by the practice, comparing new patient inquiry volume before and after the brand build. It is not independently audited, and we do not publish the underlying inquiry counts.

What we can attribute: no paid advertising was used to produce it, so the change came from organic content, search visibility, and positioning. What we cannot isolate: this was a live practice, not a controlled trial, and clinic-side factors over the same period may also have contributed. Anyone weighing this as evidence should read it as a single real engagement with a consistent direction of travel, not as a benchmark to expect.

Education first, growth second. When parents trust the source, the inquiries follow.

Dr Nisa's brand is now an ongoing platform rather than a one-off campaign, the model Purple Playhouse applies to doctors and expert-led brands who want to grow with clarity and credibility. The professional standards this work stays inside, with citations to the Malaysian Medical Council guidance, are set out on that page.
