Dr. Tim Hill

Hill Family Dentistry San Tan Valley Helping patients achieve and maintain excellent oral health gives me the most satisfaction as a dentist,² says Dr Hill. He adds that, ³I treat my patients as if they are family. One of the best things about being a dentist is having the opportunity to improve my patient¹s expectations of modern dentistry.² Many times this means providing the most conservative and minimally invasive treatment that has the least side effects. Dr. Hill is also conscious of the effect a wonderful smile has on a person¹s self esteem and provides cosmetic dentistry for his patients looking to improve their appearance. As a father of five Dr Hill also enjoys working with children. So much so, that he learned balloon origami from a professional clown so he could create balloon animals for his young patients. This type of enthusiasm is typical of the dedication Dr. Hill brings to dentistry. After graduating from the University of Nevada Las Vegas with a Bachelor of Science degree in Biology, Dr. Hill received his Doctor of Dental Medicine degree at Oregon Health and Science University. He is a member of the American Dental Association, the Arizona Dental Association, the American Association of Pediatric Dentistry, and the Academy of General Dentistry. Outside of work, Dr. Hill enjoys doing handyman work and landscaping at home, reading, and spending time with his wife of 17 years Cindy, and their family. He looks forward to seeing you and your family at our San Tan Valley office!
