Dr. Nicholas Leon-Guerrero, DDS

Dr. Nicholas Leon-Guerrero, DDS

Endodontist
2700 S Quincy St, Ste 325, Arlington, VA
Dr. Nicholas Leon-Guerrero is a board-certified endodontist who pairs meticulous technique with a calm, steady presence that immediately puts patients at ease. He has advanced training in conventional, regenerative, minimally invasive, and surgical endodontics, with a focus on preserving natural teeth while relieving pain as quickly and comfortably as possible. As a Diplomate of the American Board of Endodontics — a distinction held by fewer than one-quarter of endodontists nationwide — he is committed to the profession’s highest standards. Patients appreciate his gentle chairside manner and his thoughtful use of advanced technology to enhance comfort, predictability, and healing. Dr. Leon-Guerrero is honored to bring his expertise to Omni Endodontics in Arlington, Virginia, where a modern, calming environment and patient-first philosophy guide every decision. He begins each visit by listening closely to the patient’s symptoms, personal history, and goals, then takes the full picture into account to help them make thoughtful, informed decisions about their care. Outside the operatory, he maintains a strong commitment to service and education. He volunteers regularly at the Northern Virginia Community Dental Clinic and has provided humanitarian dental care in underserved communities across the world. He serves on the Executive Committee of the Northern Virginia Dental Society and previously sat on the Alumni Executive Committee of Columbia University College of Dental Medicine. Dr. Leon-Guerrero is recognized as a Fellow of the Virginia Dental Association for his contributions to organized dentistry. These leadership roles reflect his dedication to advancing the profession and mentoring the next generation. At home, he recharges through strength training, travel, and weekend adventures with his wife and young daughter — a balance that reinforces the empathy, attentiveness, and compassion he brings to each patient interaction.
