      My 18 year old daughter, Sadie Fisher has HLHS and has been a patient of Children's Hospital since she was a baby. She is currently under Dr. Stout's care. Sadie and I recommend and appreciate Dr. Stout as she is a knowledgeable Cardiologist and excellent with teens with have congenital heart disease. She has helped Sadie become empowered with her own healthcare as she approaches adulthood. She spends as much time as necessary with Sadie and my concerns and questions. We are grateful that Sadie can continue with Dr. Stout's care as she graduates from Children's onto UW.
