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!

It was such a pleasure meeting with Dr. Roane. She took her time and explained everything in detail to us. She is professional, patient and personable. We are grateful to have her as our daughter cardiologist. Thank you Doc!
