Today we’d like to introduce you to Hao John Chen.
Hi Hao John, so excited to have you with us today. What can you tell us about your story?
Our story has been a long arc of building bridges: between cultures and countries, between engineering and medicine, between invention and real-world outcomes, and between high standards and everyday patient care.
I’m Hao John Chen, PhD. I’m from Taiwan, grew up in Argentina, and later came to Ann Arbor to study at the University of Michigan, where I trained in Biomedical Engineering. My wife, Dr. Ruoxue “Snow” Feng, DMD, left China at the age of three, grew up in Japan, and later came to Philadelphia, where she trained at the University of Pennsylvania and Temple University before specializing in endodontics. Those early experiences – adapting across languages, systems, and expectations – shaped how we approach our work today: with empathy, discipline, and a deep respect for what people are navigating when they ask for help.
I started as a cross-disciplinary engineer with foundations across mechanical, chemical, biomedical, and electrical engineering, and later added business fundamentals to better understand how technology becomes a product. Over the past decade-plus, I’ve focused on technology translation – not just publishing research, but taking ideas through prototyping, validation, and commercialization so they can actually help people. That path led me into building teams, developing intellectual property, and bringing technologies to market through startups and industry partnerships, including efforts that resulted in successful spinouts and acquisitions. Along the way, I learned that great technology only creates impact when execution, operations, and user experience are treated as seriously as the science.
Eventually, our work converged with healthcare in a very personal way. We shared the same frustration that many patients feel: dentistry can be confusing, rushed, and reactive – especially when someone is in pain and needs urgent help. We believed a specialty practice could feel different: precise, calm, modern, and genuinely patient-centered. That belief became Biocrede Endodontics.
We built Biocrede in Diamond Bar, serving families and referring dentists across the San Gabriel Valley and nearby communities such as Walnut, Rowland Heights, Chino Hills, Brea, West Covina, Pomona, San Dimas, Covina, La Verne, and Hacienda Heights. From day one, we focused on two things: clinical excellence and trust. In endodontics, details matter. When someone has severe tooth pain, a cracked tooth, or a dental infection, they need clarity and relief – fast. We designed our systems, our technology stack, and our patient workflow around accurate diagnosis and efficient care. That includes advanced imaging (CBCT) and high-magnification microscopy, but just as importantly, it includes communication: explaining what is happening, what the options are, and what the next steps should be.
Today, Dr. Snow leads patient care, and I support the practice as COO and business development lead with a focus on operations, systems, and community relationships. We still view the work through the lens of translation: turning expertise, technology, and disciplined execution into a better experience for patients and better outcomes clinically. We are proud to be building something long-term here – a practice that earns trust locally, contributes to the community, and sets a higher bar for what specialty care can feel like.
I’m sure it wasn’t obstacle-free, but would you say the journey has been fairly smooth so far?
Not at all smooth. and honestly, the challenges were exactly what shaped the practice.
One of the biggest hurdles was starting from zero trust and zero visibility. In healthcare, patients rarely “try” a specialist the way they try a new restaurant. Referring dentists need consistency, communication, and clinical outcomes before they feel comfortable sending patients. Earning that trust takes time, repetition, and a lot of unglamorous follow-through. Operationally, the learning curve was steep. Building a specialty practice means getting dozens of details right at the same time: licensing and compliance, insurance and credentialing, systems and workflows, technology procurement, staffing, training, and patient experience. Even when you do things correctly, timelines can be slow and unpredictable – especially with payers, vendors, and platform limitations.
I learned from my previous companies I had built before – including AVALab (an animal lab serving veterinarians in Southern California), Advanced Skin Care Med Spa in New York City, and Biocrede (an R&D company). I learned that the hardest part is rarely the core service itself; it is building the operating system around it. That means hiring and training, compliance, consistent quality control, cash flow discipline, customer experience, and the day-to-day execution that turns good intentions into real outcomes.
There’s also the human side. We both came from international backgrounds, and building something in a new environment forces you to learn cultural expectations, communication styles, and business norms quickly. And when you’re serving patients in pain, you carry a real responsibility: you don’t get to “iterate” on quality. You have to be excellent from day one.
We love what we do, and my wife truly enjoys making every root canal case as excellent as it can be – and our referring doctors consistently appreciate the quality of her work.
Thanks – so what else should our readers know about Biocrede Endodontics?
Biocrede Endodontics is a specialty dental practice in Diamond Bar focused on saving natural teeth through endodontic care, primarily root canal therapy, root canal retreatment, and endodontic microsurgery (apicoectomy). Most patients come to us when something feels urgent: severe tooth pain, a cracked tooth, a failing prior root canal, or signs of infection. Our job is to provide clarity fast, relieve pain, and deliver a predictable outcome with a calm, respectful experience.
What sets us apart is the combination of precision and communication. Clinically, endodontics is detail-driven, and Dr. Snow Feng is meticulous. She genuinely enjoys the craftsmanship of making every case as excellent as it can be. We support that with a modern diagnostic and treatment workflow, including advanced imaging (J Morita CBCT), Zeiss professional microscopy, ASI Advanced Endodontic systems, and other high end technologies to improve accuracy and decision-making. But just as importantly, we treat communication as part of the care: we explain what we see, provide precise clinical advice, what is urgent versus what can wait, and how to move forward confidently.
We’re also very referral-centered. We work closely with general dentists across the San Gabriel Valley and nearby communities, and we put real effort into making their lives easier: timely scheduling, clear documentation, and consistent follow-up. Many of our referring doctors tell us they value the quality of Dr. Snow’s work and the consistency of our coordination.
Brand-wise, what we’re most proud of is trust. We built Biocrede to feel different from the typical rushed or confusing healthcare experience. Our brand is calm, modern, and patient-centered which is centered around high standards without the intimidation. If there’s one thing we want readers to know, it’s that specialty care can be both technically rigorous and genuinely human. When people are in pain, they don’t just need treatment; they need clarity, reassurance, and a team that treats their problem seriously from the first conversation to the final follow-up. That’s the experience we work to deliver every day.
What matters most to you?
What matters most to us is trust, and trust is built through precision, consistency, and how people feel in our space.
We want Biocrede Endodontics to be the kind of place that welcomes everyone. A lot of patients arrive anxious, in pain, or embarrassed that they waited too long. So we designed the practice to feel calm and dignified – more like a relaxing med-spa environment than a stressful clinic. The lighting, the cleanliness, the details, and even the music are intentional, because comfort lowers fear, and lower fear leads to better care decisions.
Clinically, what matters is precision. In endodontics, small details determine outcomes. Our goal is simple: solve the problem correctly the first time, minimize uncertainty, and help patients return to normal life without pain. That also means being honest about options – what is urgent, what can wait, and what the realistic path forward is.
And operationally, what matters is reliability. We take referrals seriously because a referral is a transfer of trust from one doctor to another. We aim to respond quickly, communicate clearly, and coordinate smoothly so the referring office and the patient both feel supported. When we do our job well, the patient feels cared for, the referring dentist feels confident, and the community benefits.
At the end of the day, we care about building something long-term: a practice known for calm excellence, high standards, clear communication, and an experience that leaves people feeling relieved, respected, and safe.
