"Texas has one of the greatest doctors. I say unfortunately because Dr. Sudath Rannulu was my daughter’s doctor when he was in New York and he’s the best pediatrician to have. Compassion. Caring understanding along with being a funny doctor. Your children are under the best care with Dr. Rannulu caring for your children."

- Melissa Stollman

"I absolutely love Dr.Ran, he is amazing at what he does and great with the kids.. No doubt in my mind about what he says because he is very experienced and so nice. We are glad he is here and look forward to what the future holds."

- Courtney Diane Christian

"Dr. Rannulu was one of the best pediatricians ever. From my 19-year-old down to my newborn, they all loved him. He always remembered details about my whole family and took the time to ask about them all. That always amazed me about him, not only that he could remember, but that he cared enough to ask! He was extremely knowledgeable, yet he also valued and respected my own “mother’s intuition” We miss him dearly in New York. If he’s in your area, our loss is your gain."

- Jacqueline Wilcox

"Doctor is amazing, fast and very good care. The doctor took the time to talk to my teenage son. He is caring and the most amazing pediatric I’ve seen so far. "

- Rosie Ramos

"Dr. Rannulu is a truly wonderful Doctor. My children were never afraid to go the doctor’s office because they loved him. In fact, they would ask to go if they felt sick! He was great at working with the parent, as well and was just an all-round nice person. We miss him dearly in NY. All the best Dr. Rannulu! "

"Dr. Rannulu is one of the best doctors that my children ever had. He always took his time to listen to my concerns about my triplets. He was their doctor for about 4 years here in NY and we miss him deeply. We are glad for his new-found success and wish him well."

- Pat Arnett

"My daughter has been seeing Dr Rannulu for over 2 years and it’s always been a quick process. My doctor has had 3 surgeries and his referrals were always timely and on point. If I couldn’t reach the specialist or their date was too far out, I would call back and Dr Rannuli would send a referral somewhere else and made sure we would be seen within a week. All my concerns are always covered, I’m a very vocal mom and you just can’t tell me anything and expect me to just be like “ok” lol so far so good. "

- Asha Johnson

"I have read some of the reviews. And I thank God for many lovely experiences I have had with the doctor’s office I have no complaints. I have been blessed since my 3 boys has been under his care. Excellent doctor that have seen my boys from toddler’s to teenagers. And has sent me to whatever specialist I have asked him to referral me to. He works side by side with children’s and 1 of my sons have had series of surgeries and they wouldn’t have got done if it hadn’t been for Dr. Rannulu pushing them to help my son so he is more than awesome him and the awesome nurse’s he has. My son had hearing lost in his left ear and he had an issue where he had a testicle removed. And if it wouldn’t been for Dr. Rannulu finding this my son would be fighting cancer at an early adult hood instead of enjoying life. And thanks to the Dr. my son can hear out of his left ear so i am very grateful to have him and it’s never been about money he has help me and my kids. Anytime my boys are sick and i call they get them right in with no problems. I love Duncanville Pediatric awesome Doctor office. "

- Rita Walker

"Dr. Rannulu is a wonderful and caring Doctor. My family and I switched over to him a year ago because the old physician wait time was over three hours every time, we had a visit and the quality of care began to decrease. And let me tell you it was one the best decisions we have ever made. We are never there more than an hour tops, but if we were it would not matter because we care about the quality of care versus how fast we get out. He’s very patience and thorough. My grandson has always been able to get an appt in a timely manner and his diagnosis has always been accurate. He gets it done right the first time!!!!! Thank you Dr. Rannulu. "
