Our Doctors

David Manzanares, DDS

David J. Manzares, DDS, FAGD, is a general dentist. Originally from Española, NM, he comes from a dental family and is the oldest son of Dr. Robert and Nancy Manzanares (a dentist and nurse/dental assistant, respectively). He graduated from Pojoaque High School in 2001. He attended the University of New Mexico as a Regent’s Scholar for his undergraduate education, graduating cum laude with a degree in biochemistry. He then attended the University of Missouri-Kansas City for dental school, graduating in 2009.

He is very active in the American Dental Association (ADA), the New Mexico Dental Association (NMDA), and the Albuquerque District Dental Society (ADDS), serving in leadership positions in all levels of these organizations. For the past three years, he has served as Secretary-Treasurer of the NMDA, where he chairs several committees. In 2016, he completed the ADA Institute for Diversity in Leadership Program. That year, he was also elected as the Representative from the 14th ADA Trustee District to the ADA Council of Communications (representing the states of Arizona, Colorado, Hawaii, Nevada, Utah, Wyoming, and his home state of New Mexico). He is a member of the Board of Directors of the New Mexico Dental Association Foundation, the charitable wing of the NMDA. He has introduced policies through the ADA which have helped to improve the standard of care that patients receive nationwide.

Continuing education is very important to Dr. Manzanares. He takes hundreds of hours every year to ensure that his patients receive the best care possible. In 2015, he was awarded with a Fellowship in the Academy of General Dentistry, an honor achieved by less than 5% of all general dentists. He has studied under some of the greatest dentists of all time, such as Drs. Peter Dawson, Gordon Christensen, and Mark Piper. He is a graduate of both the Dawson Academy and the Piper Education and Research Center. He is a member of several local and national study clubs.

Dr. Manzanares has also served as the Pre-Dental Advisor at New Mexico State University, and was a faculty member at Dona Ana Community College, teaching radiology to dental hygiene students. He has been published in Dental Economics and The Journal of the New Mexico Dental Association.
