Our Doctors
Tristin Nguyen D.D.S
Owner – General Dentist
Dr. Tristin brings both a rigorous clinical foundation and a personal connection to this practice: after earning his Doctor of Dental Surgery from the University of Maryland School of Dentistry and completing an advanced general practice residency at NYU Langone Hospital in Brooklyn, where he built a strong foundation in comprehensive, everyday dentistry and developed real depth in implant dentistry, he returned home to lead the practice his mother, Dr. Linhdai Truong, built over two decades — honoring that foundation of family-first care while bringing his own advanced training and standards to every appointment.
Dr. Tristin is Spear-trained in advanced cosmetic dentistry, using Facially Generated Treatment Planning (FGTP) — a whole-face approach to diagnosing and sequencing treatment, rather than addressing individual teeth in isolation. Every exam starts with a comprehensive evaluation of your teeth, bite, and smile as a whole system — and everything we find is shared directly with you, in plain terms, so you have the full picture before deciding what, if anything, you want to do next.
Whether you’re in for a routine visit or considering a full smile transformation, the process is the same: a thorough look at what’s actually going on, an honest conversation about your options, and a plan built with intention.

Our Specialists
Caroline Chun D.D.S
Associate – Pediatric Dentist
Originally from Houston, TX, Dr. Caroline Chun earned her undergraduate degree in Biology with a minor in Chemistry from New York University in just three years before continuing her dental education at New York University College of Dentistry. There, she received the Dean’s Student Award for academic and clinical excellence and service to the College and community, the International College of Dentists Student Humanitarian Award for leadership and exemplary character in humanitarian service, and Best Clinical Case Report at New York University Research Day for her presentation, “Interpreting Risk Factors for External Cervical Resorption in Vital Dentition.”
Dr. Chun went on to complete a general practice residency, followed by a pediatric dental residency at The Mount Sinai Hospital in New York City. There, she received advanced training in treating children of all ages, with a special focus on those with complex medical conditions and special healthcare needs. She also gained extensive experience in multidisciplinary care, working alongside medical teams to provide comprehensive, coordinated treatment. Right after graduating, she stayed on at Mount Sinai as the youngest attending in the pediatric dental residency program. She is currently board-eligible in pediatric dentistry.
Dr. Chun has a natural ability to connect with kids and ease their fears, turning dental visits into calm, fun experiences. Her approach is rooted in intentional care: she believes early, gentle treatment builds not just healthy teeth but real confidence, and she takes the time to explain every step clearly to both children and parents so nothing feels like a surprise. Each visit is thoughtfully paced to help children feel safe and comfortable, while parents are included as partners in their child’s care. Parents trust Dr. Chun for her warmth and patience, and for helping even the most nervous first-time patients leave with a big, bright smile. She treats every child with the same care she would want for her own family, and she hopes every visit leaves a child a little braver and a lot more excited to make dental visits a lifelong part of their routine.
In her free time, Dr. Chun loves traveling, trying new foods, and always spending time with her fiancé, family, friends, and her silly fluffy corgi, Bagel.
Kaylie Nguyen D.D.S, M.S
Associate – Periodontist
A Maryland resident since 2010, Dr. Kaylie Nguyen brings both rigorous clinical training and a genuine commitment to preserving your natural smile. She earned dual degrees in Biochemistry and Molecular Biology from the University of Maryland, Baltimore County, followed by her Doctor of Dental Surgery and a residency in Periodontics, both completed at the University of Maryland School of Dentistry.
Dr. Nguyen’s approach centers on early diagnosis and personalized treatment planning — helping patients preserve their natural teeth and long-term periodontal health whenever possible, rather than defaulting to more invasive options. From non-surgical therapy to periodontal surgery, regenerative procedures, and implant-related care, every treatment plan is explained clearly so you understand your options and feel confident in your decisions, not just told what’s next.
Fluent in both Vietnamese and English, Dr. Nguyen takes the time to build real relationships with her patients. Outside the practice, she enjoys cooking, exploring new cuisines, traveling, and spending time with family and friends.
