Personal Bio:
Dr. Robert N. Barber, D.D.S., has been providing comprehensive dental care for more than 24
years and is the founder of Gateway Dental Care in Gilbert, Arizona. A graduate of Case
Western Reserve University, Dr. Barber earned his Doctor of Dental Surgery degree in 2002 after
completing undergraduate studies at the University of Utah. He is licensed in both Arizona and
Kansas and has built a reputation for combining advanced technology with compassionate,
patient-centered care.
Dr. Barber has a special passion for orthodontics and has completed two years of continuing
education focused on orthodontic treatment, including both Invisalign® clear aligners and
traditional braces for children, teens, and adults. He enjoys helping patients achieve healthy,
confident smiles through conservative treatment planning and believes strongly in using the least
invasive procedures necessary to create long-term oral health.
Known for his calm personality and excellent bedside manner, Dr. Barber is especially
appreciated by children and families who value a comfortable, low-stress dental experience. His
approach focuses on listening carefully to patients, educating them on their options, and building
long-term relationships based on trust.
At Gateway Dental Care, Dr. Barber provides a wide range of services including cosmetic
dentistry, same-day CEREC zirconia and E.max crowns, restorative dentistry, orthodontics, and
family dental care. The practice features a fully onsite dental laboratory, allowing cosmetic cases
to be customized directly in the office by an experienced lab technician. This streamlined process
improves communication, enhances esthetic outcomes, and eliminates the need for patients to
visit an outside lab for shading or adjustments.
Dr. Barber is an active member of the American Dental Association, Arizona Dental Association,
Central Arizona Dental Society, and the International Association for Orthodontics. Outside the
office, he enjoys serving in his church as a leader for adult men and values giving back to his
community through mentorship and service. When he is away from the office, Dr. Barber loves
spending time on the lake with his family, including his three children and six grandchildren.
