Bedside manner. She is wonderful and kind and always available for questions. I have never waited more than 12 hours for a response from her. Wonderful for a new mom.

Dr. Arnaout is kind, smart and funny. She is great with both of my kids and makes them feel comfortable. She is incredibly knowledgeable and always stays current on the latest research. I appreciate how responsive she is to emails. The short wait times at this office are a huge plus too.

Dr. Diane takes the time to fully explain your child’s situation and health in a way that both educated and eases a parents worried mind. She is thoughtful, caring and enthusiastic about her patients. I wouldn’t take my three kids anywhere else.

- Ashley, Fort Worth

She is the best. Makes you and your child feel at ease no matter the issue. My daughter especially loves that she talks to her directly on her level.  She becomes your child’s friend and partner.  My oldest child is 25 and the youngest is 8. I seen my share of pediatricians, trust me. She is the best!

- Deborah, Lipan

Dr. Diane is not only an exceptional pediatrician, she is an incredible person. She loves her patients and it shows in every interaction. She takes the time to not only listen to the parents but also to the child. Building relationships and trust throughout the appointment is a skill that is more appreciated than words. Her knowledge and constant pursuit of further research makes her invaluable as a pediatrician.

- Elisha, Azle

In addition to a helpful staff, zero wait times ever, and kind nurses, Dr. Arnaout is incredibly kind, knowledgeable, responsive, and genuinely cares about her patients. She often tells me to “trust your intuition” and can reference up-to-date information for nearly anything I ask about. She truly cares about the whole child and makes an effort to get to know them and their interests. We would drive across the metroplex to see her, but blessedly she’s conveniently located across the street from the zoo.

- Erin, Fort Worth

She loves her patients like her own kids. Always gets my daughter in the day I call, and we see her. I can email her anytime of day and she herself responds within no time.

- Felicia, Weatherford

Dr. Diane has an amazing attitude and engages with my kiddo during each visit. Quick questions that I send over via email are answered quickly, and appointments aren’t hurried because she spends time going over any questions I may have or giving me follow up information and milestones my kid should be hitting before our next visit.

The location is great, the waiting room and individual care rooms are always clean, and have toys set up to keep kids occupied and distracted. She is very informative, has great communication and writing skills, and is very open about caring for kids in a world that seems to be overwhelmed in the anti-vaccine movement and diluted more and more with essential oils as “medicine.” Setting up appointments is easy too. We love Dr. Diane!
