You won't be disappointed.”

Whitney M.

“ The staff was so patient and understanding with my autistic son. It’s sometimes hard to find doctors/staff who treat children with autism with respect but everyone was so kind and worked with us throughout a difficult visit for x rays. Dr Abraham also asked lots of questions and seemed to really care about her patients. I would recommend them to anyone with small children! :) ”

Brittany B.

“ What a great place! From the moment my child walked in, we were promptly greeted with smiles and made to feel welcome. The first dentist visit (especially for a 15-month old) can be a scary place, but Dr. Abraham and her team made us feel instantly comfortable and taken care of. My little even held the assistant's hand! Great care from a caring team and all smiles from the smallest of patients is a win, win, win!! Thanks, Castle Hills! ”

K. D. P.

“ My 4 year old had her first appointment and I was so pleased. From the time we walked in the door there was a gentle and happy atmosphere. The office is colorful and calming. The person giving her x-rays was patient and explained everything to my curious little person. Then cleaning her teeth was a breeze and fun. The doctor was very knowledgeable and friendly and I appreciated her expertise. Overall wonderful experience and I am very pleased. Can't wait to return for checkups! ”

Ty A.

“ Beyond amazing! My husband and I we’re kind of worried how our daughter would react with her first ever dental appt here in the US that he has to take a day off from work to be there for it. Days prior to her appt she kept telling us she is scared. But on the day of the appt, SHE DID GREAT!! Nothing we expected at all, not even what we hoped for her reaction, to say the least. She sat still most of the time and listened to the instructions the dentist told her. She kept telling us she enjoyed the whole process afterwards. ”
