"My mom used to say, 'When God closes a door, He always opens a window.' I have found that to be true many times in my life. My life as a pediatrician is a result of crawling through an open window when the door I thought I was supposed to walk through was closed to me."

Jason Terk, M.D., Keller, Keller Parkway

"Florinda Peak, the most amazing Mommy in the world, to 5 year old Dr Sandra Peak who did not want to practice reading… 'You have to learn how to read…because when you do the whole world opens up to you!'”

Sandra Peak, M.D., Lewisville

"The best advice my mother ever gave me was to give to others without expecting anything in return. (She also told me to never go outside with wet hair because I’d catch a cold, but medical school later disproved that. Sorry mom.)"

Diane Arnaout, M.D., Willow Park

"The best advice my mother ever gave me was, “never miss the chance to use a perfectly good bathroom” when you are out of the house."

"My mom told me to respect (be nice) to the nurses because they can either make or break your day."

Samuel Sheng, M.D., Arlington Neighborhood Clinic

"Encourage others. She always wrote notes to people for accomplishments, during sad times and just because."

Justin Smith, M.D., Lewisville

And finally, our favorite advice ...

"Marry Joan."

Tom Rogers, M.D., Forest Park. Dr. Rogers and his wife Joan have been married 59 years and today, she is a proud mother. "Joan worked to pay my way through medical school, gave me two great kids who are both pediatricians, and has allowed me to work without having to pay attention to small things like finances, maintenance of our house and yardwork. I couldn't be where I am today without her," Dr. Rogers said.

Happy Mother's Day from all of us at Cook Children's ...
