My professional career spans nearly 17 years, with the last 15 in Endodontics. I am passionate about my work and am honored to be consistently listed amongst the “Top Endodontist” in the D.C. Metro Area.

General dentists partnering with me know that I am reliable and responsive to their needs, which means caring for their patients. I accept challenging cases and place a high priority on emergencies, treating referral patients with the same level of care they are already accustomed to from their own dentist. I am always available to discuss individual cases, especially when it is necessary to deviate from the original plan of treatment, and I encourage dentists to attend my demonstration workshops.

I believe in keeping patients informed throughout the process of their root canal so they know what to expect. I have found that it helps to calm their fears if they know I am being “patient with the patient.” I can visibly see people relax little by little, and it makes me feel better to know they are at ease and trust me to provide a painless treatment. I personally monitor the status of my patients’ post-treatment healing through after-hours phone calls.

I have carefully chosen my staff and frequently receive compliments about their friendliness and professionalism. That is important because I want my patients to see that we are united as a team, and that our goal is not simply customer service—it’s patient compassion.

On a personal note, I am dedicated to my family, my practice, and my community, and I find great satisfaction in volunteering for Mission of Mercy (M.O.M.) projects and serving in leadership positions for various dental associations.

Honors: Pierre Fauchard Academy Fellow, International College of Dentistry Fellow, American College of Dentistry Fellow, Academy of General Dentistry Fellow, Washingtonian Top Endodontist

Education: Master of Science, George Washington University; Doctor of Medical Dentistry, University of Puerto Rico School of Medicine; Certificate of Endodontics, Walter Reed Army Medical Center

Member, Dentistry: Northern Virginia Dental Society (Past President), American Dental Association, Academy of General Dentistry

Member, Endodontics: Virginia Academy of Endodontics (Past President), American Association of Endodontists

Faculty Position: Part-time faculty Assistant Professor in the department of Endodontics, Virginia Commonwealth University School of Dentistry.

I am a board certified endodontist with over 30 years of experience in the practice of endodontics. My experience includes 20 years in the U.S. Army, where I served as assistant director of the Advanced Endodontic Training Program and earned the “A” Prefix for excellence in endodontics from the U.S. Army Surgeon General. I have also served as clinical instructor of endodontics at the Medical College of Georgia and assistant clinical instructor at the Medical College of Virginia.

General dentists rely on me to care for their patients in this manner, and I appreciate the genuine feedback I receive about my reassuring chair-side manner. I am very proud to say that I work with a highly-skilled and courteous staff and their dedication helps each of our patients to have a better experience than they imagined.

I have served in leadership roles for dental associations because I am committed to the profession and wish to motivate other dentists to reach the highest levels of professionalism and compassion. Another role of importance to me is volunteering for the Mission of Mercy program, providing free dental services to the underprivileged.

Honors: Virginia Dental Association “Top 40 Under 40”; Awards from American Association of Oral Biologists and American Association of Endodontists; Phi Beta Kappa, Delta Epsilon Sigma, and Sigma Xi; Eagle Scout, Boy Scouts of America

Education: Bachelor of Science in Biology, Bachelor of Arts in English Literature, Saint Michael’s College; Doctor of Dental Surgery, Certificate of Endodontics, State University of New York at Buffalo School of Dental Medicine

Member: Northern Virginia Dental Society, Virginia Dental Association, American Dental Association, American Association of Endodontists, American Board of Endodontists (Candidate), Korean American Dental Association, Alpha Omega Dental Fraternity

My experience in endodontics is both on a clinical and academic level. While at the University at Buffalo, I taught predoctoral students endodontics both in the preclinical technique course and in the clinic with patients. I still maintain a love for teaching and will travel back to Buffalo to lecture the postgraduate endodontics residents. In this practice, we often host demonstration workshops and lectures for referring doctors.

General dentists who work with me appreciate my attention to detail in caring for their patients. It is my philosophy that emergencies must be dealt with on a same-day basis in order to put patients at ease. Additionally, I am always more than happy to discuss cases with referring doctors over the phone, both cases I have treated myself and cases a doctor may be looking to undertake themselves.

Personally, I enjoy everything the northern Virginia area has to offer. My wife Stella and I enjoy hiking, kayaking, and exploring the culinary scene in the DC area. We also enjoy volunteering for the Mission of Mercy (M.O.M) project where we offer free dental care to those in need.
