About the Guest
Alfred Griffin is the co-founder and CEO of LightForce, the developer of the world's first fully customized, 3D-printed bracket system for orthodontics. He holds a DMD and PhD in Craniofacial Biology from the Medical University of South Carolina and completed his orthodontic residency at Harvard School of Dental Medicine, where he currently serves as faculty and the Board of Fellows. Alfred remains an ABO-certified practicing orthodontist.
Interview Summary
Alfred is rethinking one of the most established categories in medical technology: braces. Trained as an orthodontist while still seeing patients today, he approached the problem from inside the system, not as a technology gap, but as a design flaw hiding in plain sight.
Orthodontics had already seen major innovation with clear aligners, unlocking a new adult market. But that progress left behind the largest segment: teens who make up roughly 75% of the patient population still rely on traditional brace brackets that haven’t changed in multiple generations.
With LightForce, each bracket is customized to the patient’s anatomy and treatment plan, eliminating inefficiencies that come with off-the-shelf braces. In fact, a clinical study published in early 2026 showed 43% shorter treatment times and 60% fewer office visits.
Adoption of LightForce’s novel technology required change across clinical, operational, and economic workflows. And scaling the company proved equally difficult. Each patient case requires approximately 86 unique, high-precision parts, manufactured on demand, with full traceability. LightForce consolidated engineering, software, and manufacturing under one roof in a “digital factory” in Wilmington, Massachusetts, turning operations into a key moat.
Founded in 2015, LightForce received FDA clearance and treated its first patients in 2018. Since then, LightForce has been used by nearly 200,000 patients, and 51 of 66 North American orthodontic residency programs are trained and actively teach this technology in their clinics.
Top Takeaways
Look for treatment gaps hiding inside the established patient solutions. When the failure point of an existing solution is the user, redesigning the tool to remove that variable can unlock a far larger market. Applying modern technology to a better-designed solution can drive adoption by delivering what clinicians and patients actually want: shorter treatment, fewer visits, and better outcomes.
A clinician-founder's edge isn't just domain knowledge — it's proximity to decisions that data alone can't inform. Know what your strengths are, be honest about the gaps, and build your team around those specific needs. Stay close to the customer even as the company scales and choose investors not just for capital, but for the expertise they bring.
Treat adoption friction as a design problem, not a sales problem. Every disruptive technology removes a problem users once accepted as permanent — your job is to help them see it. Map the full scope of behavioral change you're asking of end users: clinical, operational, and economic. The rate of adoption is limited by the new things people need to learn. Become an active facilitator of that change, and evaluate every product decision by whether it reduces the learning burden or adds to it.
When creating new markets, design the company to scale the category, not just the product. Treat scaling operations as a core product problem — not a logistics afterthought. The operational infrastructure required to scale could be your defining moat. Bringing engineering and manufacturing under one roof can accelerate iteration and compound quality gains.
