Diane Arnaout, M.D.
Dr. Diane Arnaout joined the Cook Children's Willow Park practice in 2011. Dr. Arnaout was born and raised in the Dallas-Fort Worth area. She attended college at Texas A&M University and medical school at the UT Health Science Center in San Antonio. She did her pediatric internship and residency at Children's Memorial Hermann Hospital and M.D. Anderson at the Texas Medical Center in Houston, TX where she served as a leader on the medical education committees. She is a board-certified pediatrician.
After working in Houston for a year, she and her husband decided it was important to be near family, and happily returned home to DFW. Dr. Arnaout is an active member of the American Academy of Pediatrics, and is the president-elect of the Fort Worth Pediatric Society. She loves all aspects of her job, especially caring for newborns (and new parents) and helping children thrive into their teenage years.
Her favorite pastimes include reading, cooking, eating, photography (especially children's photography!), and spending time with her family. She and her husband Drew live in Fort Worth with their son and daughter.
Dr. Arnaout is also an active contributor to Cook Children's Checkup blog. Her most recent articles can be found here.

Devona Martin, M.D.
Dr. Devona Martin joined the Willow Park practice in 2016 after working as a hospitalist at Cook Children’s Medical Center since 2012. She grew up in East Texas and attended Baylor University. There she was a University Scholar, spent a semester in The Netherlands studying the history of medicine, and graduated with honors. Her medical training was at Texas Tech University Health Sciences Center in Lubbock where she was inducted into the Alpha Omega Alpha honor society. Pediatric residency training was also completed at Texas Tech where she served as chief resident. She is a member of the American Academy of Pediatrics and is a board-certified pediatrician.
Dr. Martin began as a pediatric hospitalist in Lubbock and was involved in medical student education as well as child abuse pediatrics. Once the opportunity arose, she and her husband were excited to move closer to family. She began working as a hospitalist at Cook Children's Medical Center and served on the medical education committee and as site director for the A&M medical school pediatric rotation.
Pediatrics was a natural choice for Dr. Martin. She enjoys caring for medically complex patients and is passionate about prevention of child abuse. Being a mother of three children is the greatest joy of her life and motivates her to care for others’ babies as she does her own. She, her husband Jay, and three children live in Aledo and love the sense of community and small town atmosphere.
Jenica Rose-Stine, D.O.
Dr. Jenica Rose-Stine joined the Cook Children's Willow Park practice in 2008. She is a TCU horned frog who has been voted to the list of Fort Worth Top Docs annually since 2009, and she serves on several community boards including the CASA Advisory Board of Parker and Palo Pinto counties and Board of Directors for the Aledo Education Foundation. She is passionate about advocating for child health, safety, and wellness. She loves teaching parents how to “grow” their children to reach their full potential, and she especially enjoys interactions with first-time parents and their newborns.
"I can truly say I have my dream job. I work and live in a wonderful community, where I interact with my friends' and neighbors' children. Watching these kids grow up has been a joy, and I hope someday I will take care of those patient's kids! Now that I have kids of my own, I really enjoy the conversations with my patient families as we raise our kids together. I think of it as an on-going conversation we will be having for the next eighteen years."
Dr. Rose-Stine's husband, Matthew Stine, is a family physician in Willow Park. The couple met in college and married in medical school. They have one daughter and one son. Dr. Rose-Stine enjoys being outdoors, reading, running, and chocolate.
