      I had dealt with incredibly irregular heartbeats throughout middle and high school with multiple emergency room visits that ended in being told I had anxiety or it was a gastrointestinal issue. It took an EMT arriving to my high school and taking an EKG to get the diagnosis and treatment on track. Soon after this I met Dr. Ruggerie and he quickly honed in on an accurate diagnosis in a matter of months. I soon traveled to Seattle Children's for heart surgery. What could have been a nerve-wracking experience was made very comfortable thanks to the receptionist, surgeon, anesthesiologists and post surgery nurses. I cannot describe the profound effect Dr. Ruggerie and Seattle Children's Hospital had on me and my family and I cannot recommend them enough.

      This man has been a godsend to our family. He is on top of everything, goes above and beyond to make sure your child is healthy and getting the best care. He helped us through our questions and concerns every time we had them. He takes as much time with his patients as they need. He does research on any disorder that may effect the heart and he takes the extra time to check that it isn't effecting your child. You will be in the best hands I can think of. My son has been a patient from 3 months old and I truly recommend him for any child.

      Dr. Ruggerie is our hero. He has been my son's doctor his entire life and if it were not for this man's dedication and true concern for his patients my child would not be here. He even flew with us to Boston when my son needed emergency heart surgery at 8 months. This man is truly an angel and will forever have a special place in my heart. What else do you say about someone who has saved your child's life?
