Dr. Nina Coto, DDS
Dr. Nina Coto is a general dentist at River Dental in Siloam Springs, Arkansas. She was born in Los Angeles, California and when she was 10, her family moved to Spring, Texas.

She graduated college from Texas A&M University in College Station, Texas where she majored in Health with a Minor in Business. She then attended Texas A&M School of Dentistry (previously known as Baylor College of Dentistry) and graduated this year, 2023!
