Dr. Nicholas Leon-Guerrero
Endodontist | Endodontics
My name is Dr. Nick Leon-Guerrero. I grew up in Modesto, California and attended college at the University of the Pacific. I continued at the University of the Pacific in San Francisco, CA for my dental school training and finished my degree in 2014. After that, I completed a one year General Practice Residency at Kings County Hospital in Brooklyn, NY. After one year in private practice, I decided to further my training with a two-year endodontics residency program at Columbia University in New York, NY. After graduation, I started private practice with Limited to Endodontics in Boston, MA. Currently I live and work in Arlington, Virginia with several outstanding colleagues at Dominion Endodontics. We have additional office in both Falls Church and Alexandria, Virginia. I love working here and taking care of my wonderful patients, but I am always excited for new opportunities. I love the power endodontics has to save teeth. Our specialty is taking great strides in patient care by embracing fundamental ideas of the past and incorporating new innovative methods to provide the best care possible. I enjoy practicing at the cutting edge with regenerative, minimally invasive, and surgical techniques to reach patient-centered outcomes. My priority is always to provide successful treatment and gently alleviate pain for my patients.
