Dr. Javier Lazaro

Dr. Javier Lazaro, a native of Puerto Rico, received his DMD from the University of Medicine and Dentistry of Puerto Rico, Rio Piedras in 1989. Dr. Lazaro practiced dentistry in his private practice in Puerto Rico until 2008. In March 2008, he and his family moved to North Carolina when he accepted the position as the Dental Director for the Forsyth County Department of Public Health. In April 2016, he joined our Happy Tooth in Mount Airy as our general dentist. Since at a very young age, Dr. Lazaro was interested in painting, drawing and repairing things, talents he inherited from his parents and grandparents. He feels that dentistry combines all these elements. Dr. Lazaro uses his extensive training and his 27 years of experience to help patients with challenging dental cases. He has the ability to design the most beautiful dentures, crowns, and bridges, to near perfection.

Dr. Lazaro has been happily married to his beautiful wife, Zoraida, for 26 years and they have two amazing daughters, Cristina and Andrea, who are both college students. In his free time, he enjoys reading, jogging, outdoor sports, and spending time with his family and friends. He would love to learn how to play a musical instrument one day. If he could have one super power, he would like to have the power of healing.

Dr. Lazaro speaks fluent Spanish and is very excited about being in Mount Airy, and he is looking forward to meeting all of you!
