Meet Dr. Diane Arnaout

As a Star Wars fan, I am reminded of an important quote from teacher to student: "You’ve taken your first step into a larger world," Obi-Wan Kenobi tells Luke Skywalker as he is deep in training to become a Jedi. And, like Obi-Wan, I am here to help you learn the Force.

The Parent Force. The thing that keeps you up at night, breaks down your walls, and makes you feel vulnerable and scared. I’m here to guide you through that, and better yet, help you to conquer it. We can learn some lightsaber skills too, if you want.

I didn’t realize how important the job of the pediatrician was until I had kids of my own. My education, experience in medicine, and cocky attitude made me feel like I knew it all before my first one came around. He proceeded to make me very aware of how little I actually knew.

Thankfully he survived, as did the next one, and they’ve helped me to grow and to help YOU, the parent, in so many ways. Sure I’m here to make sure your kids are healthy and happy at all ages. But I’m also here to make sure you’re educated, to make sure your family is thriving, and to make you feel confident in caring for your kids. From diaper rashes to sleep problems to school difficulties - I’m here to help.

I write a lot about common problems and ailments online – you can find me busy on Facebook and Instagram, and I write articles for the Cook Children’s Checkup Newsroom blog. A lot of stuff you’ll hear me say in the office will be typed out on there, too. And we’re in a day and age where the internet helps make connections – you can connect with me on there, or e-mail me anytime.

It takes a village to raise a child – and I’m so grateful to be a part of yours. And as Master Yoda teaches us – “Always pass on what you have learned.” I fully plan to!

Dr. Diane was wonderful with my daughter. She was very relatable as a mother and I appreciated her demeanor. It was very easy to get along with and as far as her medical assistant goes, she was wonderful. That was the first time my two-year-old had ever had a nice experience getting her weight, temperature and measurement. She had never behaved for anyone like that. I have already recommended to everybody I've met, to go to this office. I love it. – Patient family
