      Dr. Fernandez is a phenomenal doctor! His knowledge, bedside manner and communication with us and our daughter were amazing. He really listens and takes his time explaining. Dr Fernandez we are so grateful for you…

    • Deb Seattle WA 06.24.22

      Dr. Fernandez is a gem! Our daughter who has had kidney stones since age 9 began seeing him in 2020, soon after he arrived at SCH. He is an exceptional listener, takes the time to explain everything and answer questions. Dr. Fernandez has a wonderful bedside manner. We have been so pleased with his care of our daughter...we're sad that she'll be too old to continue seeing him after this year.

    • Evgenia Bellevue,WA 06.15.22

      Dr Fernandez performed a surgery on our 1 year old son. We were very nervous, but the surgery went well. The whole team, including anesthesiologist and nurses were great. They were very supportive and informative. Thank you for doing this work and helping our children!
