What our familes say

Dr. Sivadasan is absolutely, hands down the best pediatric doctor we have ever had. She's detailed and very patient. She genuinely cares about her patients. To add icing to the cake, the whole staff from the front desk to the nurses, everyone is patient and so very kind.

love Dr. Sivadasan! She is very warm and compassionate- took the time to answer our questions and address specific concerns without feeling rushed. The friendly staff made our visit smooth and easy. I like being able to book appointments, ask questions and see lab results in a convenient way on-line and on the app.

Dr. Sivadasan and her team have been wonderful with both my daughters. She is very gentle with the children and is great with answering all our questions. Scheduling sick visits has been quite easy and her team also ensures that there is minimal wait.

Dr. Raj and Dr. Sivadasan are super patient and understanding. They listen to your concerns and address every single question you would have. Not to mention you always get super responsive feedback and replies from them.

Dr Raj is such a great pediatrician! I love that she really listens to us parents with our concern about our kid. I love that she errs on the side of caution of just not over prescribing medicine like how some docs would just go get you in and out.

Dr. Rajadhyaksha is a fantastic physician. We were new to Texas and I was referred to her from our insurance company. She is very professional, caring and a great listener. She is thorough with her assessments, great with my children and very knowledgeable with disease processes.
