Dr. Hua is an outstanding cardiologist. As a mother of a little one with heart problems, she made sure that I understood exactly what the issues were, and she made sure that I knew each of the possibilities and the plan going forward. She welcomed questions and concerns, and she has a welcoming and comforting presence. I would heartily and enthusiastically recommend her for any pediatric cardio needs. She is the best!

Dr. Hua saved my grandson's life. When we took him in for his checkup, his pediatrician thought she heard a murmur. Dr. Hua came in immediately and soon we knew he had a significant heart problem. Dr Hua stayed late and was so kind. Sure helped us navigate getting to specialists in Denver, and has been doing follow up since his surgery. She has always answered our questions and is available when we've needed. I cannot find words to thank her enough!
Caitlin Skinner

Dr. Hua has been with us since before our little one was born, and we wouldn’t change a thing in terms of our experience. She is caring, reassuring, honest, and attentive. She’s also an excellent pediatric cardiologist who discovered an additional, rare heart condition in our son that had been previously missed by specialists in Denver. We’ll stick with her forever!
