The Voice of Digital Health: A Conversation with Siuwin Wang

When Siuwin Wang speaks, it’s immediately clear that his insights are shaped by both a deep curiosity and a lifelong commitment to healthcare and technology.

Siuwin Wang is the Director of Digital Health at Halton Healthcare in Oakville, Ontario. With a career that bridges computer science and healthcare, Siuwin brings a unique perspective to the challenges and opportunities in health information management. His roots are grounded in a family of medical professionals and technologists: his grandparents were physicians, and his mother worked in computer engineering. That early intersection of healthcare, technology, and discipline formed the foundation of his career.

“I started playing computer games when I was four,” he recalls. “That was before Windows even existed. From the beginning, I was curious about how things worked under the hood.” It was that curiosity that carried him through school and into the healthcare sector, where a volunteer placement in a pre-admissions clinic introduced him to the world of health information management (HIM). Encouraged by a mentor, he pursued formal education in HIM, and he has never looked back.

One of the defining qualities of Siuwin’s approach is a constant pursuit of efficiency and value. “When I encounter problems, I don’t just want to solve them,” he explains. “I want to find the most efficient and impactful way to do so.” That drive has guided him through roles in data analytics, digital transformation, and artificial intelligence.

Siuwin is also a CHIM professional and part-time instructor at George Brown College. He credits the CHIM designation with instilling the values and ethics that have shaped his approach to data and health systems. “It helped me build a solid foundation in both clinical and non-clinical operations. You become a kind of knowledge broker,” he says. “You have to understand how data flows, how it’s used, and how it ultimately supports better patient care.”

Through both teaching and leadership roles, Siuwin is passionate about sharing this knowledge. At Halton Healthcare, he frequently introduces colleagues to resources like the CIHI education portal and emphasizes the importance of understanding the full data spectrum—from collection to reporting to strategic decision-making. “Every point of data connects back to patient outcomes, funding, quality improvement, and experience,” he says.

Looking ahead, Siuwin sees the biggest challenge in healthcare as foundational: improving data infrastructure and system integration. While AI is generating excitement, he stresses that it all begins with solid, consistent data collection. “Before we talk about AI solving problems,” he says, “we need to ensure the data is clean, reliable, and interoperable.”

System integration is another priority. “Each healthcare provider hosts its own data,” he notes. “But patients move across systems. Without integration, how can we really map patient journeys?” He points to privacy rules and technical silos as barriers but believes the long-term solution lies in partnerships and cross-industry collaboration.

He is realistic about the hurdles, especially in a post-COVID era of tightened budgets, but also optimistic. “We need to walk people through change,” he says, pointing to frameworks like the ADKAR model—Awareness, Desire, Knowledge, Ability, and Reinforcement—as useful strategies in change management.

His advice for HIM professionals? Stay curious. “You don’t have to be an expert in everything,” he says. “But you should understand what’s happening, what tools are available, and what value they bring. Reflect on your interests and strengths. Build from what you’re already good at and fill in the gaps where needed.”

As for the future of Halton Healthcare, Siuwin has a clear vision: people first, then process, then technology. He is focused on workforce upskilling, strategic recruitment, and driving digital health projects forward. He also leads the organization’s AI portfolio and is actively developing system-level partnerships to bring innovation to life.

“Innovation in healthcare is often under-resourced,” he says. “But that doesn’t mean we stop. We look for creative ways to solve today’s problems and build the foundation for tomorrow.”

Whether through mentorship, education, or leadership, Siuwin Wang is helping to shape a future where digital health is smarter, more integrated, and deeply human.
