My son's pediatric cardiologist is Dr. Parrish at UC Davis Medical Center. He is great and his office number is ###-###-####. Also if you are interested, I am part of a support group called Hearts of Hope (http://sacramentoheartsupportgroup.blogspot.com) and we have members who could tell you more about any pediatric cardiologist you choose.
Best of luck in your doctor search!
