Hoping your little one doesn't need a cardiologist...if you do, I HIGHLY recommend Sierra Pediatric Cardiology! I was referred from our pediatrician for a heart concern. We visited the office on Friday and I was nervous and anxious as any parent would be. We were greeted with Anna who was friendly and patient while I was filling out the check in paperwork. She was also the one that took his vitals and did the EKG. During this time, she ask about any hereditary heart conditions in the family. She treated my little one with care and talked thru everyone that she was doing to my little one which helped him be calm and cooperative. After the EKG, we went into another exam room to wait for Dr Lai with the echo. It was a short wait unlike some of the other medical offices. Dr Lai was very friendly asked the same hereditary heart conditions as Anna which I really appreciated cause it showed that they were thorough and Dr Lai wanted to ensure that we were all on the same page. The echo started and Dr Lai also described everything that she was going to do ( like this wand was a camera to help her look at the heart and the gel was going to a little cold,etc). When the echo started , she took her time with every image and did NOT rush any part of the echo. One of the best parts was that when the echo started, she took out an iPad so my little one had something to keep him calm and still. A few more good things that I liked...completely the forms in a iPad, the waiting room had a toy car table to keep the little one entertained, the rooms were decorated so cute and the exam room had a toy that keep my little one busy. After the exam for being so good and cooperative, Dr Lai gave my little one a toy. I would absolutely recommend Dr Lai and team! Sending you and your little one positive vibes if you are reading this
