What Our Patients Are Saying

Dr Teymuri was absolutely amazing. We came in with a non-vocal verbal autistic preschooler, so we obviously had concerns with how testing would go. He took the time to come out and speak with us on the best way to communicate with him, as well as speaking to him directly instead of leaving him out as many providers do. When it was time for testing and imaging, both he and his staff were wonderful, patient, took their time and didn’t push faster than he was ready. It goes without saying that this is a rare occurrence anywhere but especially in medicine. I cannot recommend highly enough!

Dr. Teymouri and his nurse were both amazingly patient and kind with my special special needs child. The doctor took the time to get to know my child and his communication style ahead of us going back to triage and was very patient while doing the echocardiogram later. His nurse was equally as patient of and wonderful while taking his vitals and an EKG. I would definitely recommend this practice!

We want to give a shout out to Michelle - at the Herndon office who went the extra mile to help our daughter with a situation that needed immediate attention. Even though it was a super busy Monday - she took the time to make sure we received what we needed. We are so grateful for her assistance and care!

Dr. Barlow & his team have been treating my daughter since she was just days old. She is 7 now and has had 2 open hearts & 1 cath procedure. I wouldn’t trust anyone as much as I do these people with my child and her heart! My daughter was stubborn and really gave them a hard time as she was young, confused and inpatient. Him and his team NEVER made me or her feel bad about it and years later she now gets excited to see them. They have won us both over and I recommend them to anyone I know who’s child may have heart complications as well. I could never tell you in this review ALL the ways they have bent over backwards to help my child, given her the BEST care possible and going to bat for her health against health insurance companies. Him and his staff are truly the BEST in our book! You just don’t find people like this in the health care realm anymore … They truly care for their patients and want the very best for them and go to whatever lengths possible to see that your child gets exactly what they are in need of. They are NOT just Dr’s, Nurses or receptionists… they are ANGELS and ones we are incredibly grateful for!

If I could give more stars I would! Dr. Hasan and Hala have treated my daughter who has very complicated type of POTS since she was 16, and have given her quality of life back. Now, my other daughter needs them and we have her first follow up appointment today! Such caring doctors who take time to listen and very very thorough. I could not dream of a better team for my girls!
