Meet Dr. Luke Cielonko

At ten years old, I was diagnosed with Type I Diabetes. I was afraid and confused by the responsibility of checking my blood sugar, knowing everything that I ate, and taking my insulin. My family and I were now responsible for the course of my health. My fear dwindled, though, as I was filled with peace by the reassurance of my pediatrician. Through his own experience of having type 1 diabetes, he related to the doubt, the fear, and the life changes I would be facing. He showed me I could have a normal life, one in which I was managing my diabetes and not my diabetes managing me. I knew after this I wanted to be a pediatric endocrinologist so I could help others the same way.

Managing my diabetes has given me a passion for facing the complexities and subtleties required to live a happy, healthy life with a chronic disease. Through my pediatric residency training in Columbia, South Carolina and my fellowship training in endocrinology at Phoenix Children's I have an even greater appreciation and understanding of the relentless focus families need to care for their child. Whether it's diabetes or another complex disease I have a passion for families and children to understand their disease and to empower them to make the most of a difficult situation.

Outside of medicine I enjoy spending time with my family whether that's spending time outside, taking my dog for a walk, or having a dance party to Frozen or Encanto at home. I am the oldest of three and enjoy seeing my family now that we are back in the great state of Texas. I also enjoy being involved with my church community, rooting for the Green Bay Packers (Yes, I own a cheese head), gardening, playing the trumpet and supporting ministries like Compassion International where I write letters to my sponsor child.

If you choose me as your child's doctor I promise to listen and support you and your child to team up and take on whatever it is you may face.
