A Northwestern University alumna and born in Chicago, IL, Dr. DeSanto has been creating beautiful smiles for adults and children for almost 20 years.

Dr. Elizabeth Knoedler

After graduating from the University of Illinois, Dr. Knoedler attended Southern Illinois University School of Dental Medicine. She is a native of Springfield and excited to be back serving her community and her home town.

Together they are actively involved in the following organizations and academies:

• American Academy of Cosmetic Dentistry (AACD)

Dr. Tanya DeSanto was inducted into the International College of Dentists, the oldest and largest international honor society for dentists, in 2015. She takes continuing education seriously, knowing how important this is in using the latest technology to care for her patients. Although the state of Illinois requires that dentists complete a minimum of 16 hours of continuing education each year, Dr. DeSanto completes about 80 hours–five times what is required.


She enjoys other distinctions. She is the founder of the Prairie Academy of Cosmetic Dentistry. She is one of the twenty dentists in Illinois with a license for IV sedation. And she is on track to become the first accredited cosmetic dentist in the Springfield area.


She has also been elected to be on the national board of directors of the American Academy of Cosmetic Dentistry, which is a measure of the respect she enjoys among her colleagues.
