"I must say that Upland Smiles was very patient with my 2 year old. They were so gentle and loving, I was so much at ease! Even though they weren’t able to get X-rays they just assured me that they would try at the next appt. They didn’t want her experience there to be scary. Thank you very much!: KARIM B.

“I liked the fact that the dentist personally called me to see how I was doing, also the fact that when calling after business hours the dentist returned my call within 30 min.
