Dr. Jean McAtee joined UTMB Pediatric Community Based Clinics in 1995 after completing her pediatric residency at Baylor College of Medicine.  She earned her medical degree from the University of Texas Health Science Center in Houston.  With a commitment to ongoing continuing medical education, she maintains board certification by the American Academy of Pediatrics. She also serves on the school health advisory board for CCISD.

Dr. McAtee's practice focuses on preventative care, including maintenance of childhood immunizations, promoting safety measures and encouraging families to help their children maintain a healthy body weight.  As a mother of four children, she understands the concerns of parents; therefore, she encourages active involvement from them regarding their children's health care.  Her scope of practice includes patients from birth through 18 years of age.  In addition to treating common childhood illnesses, she has experience in caring for children with allergies, asthma, atopic dermatitis/eczema and attention deficit disorder.

Married for 36 years to Dr. Tommy Sim, an allergy/immunology specialist in Friendswood, TX. Dr. Sim is a proud mother of 3 children; Tom, diagnosed with Autism, graduated from University of Houston in HRM, currently employed at UTMB Health Clear Lake Campus hospital; Timmy, graduated from Baylor University with a BS in Biology, currently schooling in Computer Science at UHCL; and Theresa, graduated with a BS in Chemical Engineering from UT Austin. I feel empathetic to parents with children with disability. I feel a need to share my family's story about my eldest son with Autism and maybe can inspire somebody like him to strive and succeed.

I am grateful for the opportunities that came my way. I am honored for the trust that parents have given to me to take care of their children's health. I feel rewarded when I see my patients grow up healthy and become good citizens.

Her professional associations include the Texas Pediatric Society, Bay Area Pediatric Society and the Harris County Medical Society.

She believes that good listening leads to good care and appreciates the opinions of parents.

In her spare time, she enjoys playing the piano, reading and traveling with her family.

I grew up in Clear Lake myself, so I was very excited to become a part of this UTMB Clear Lake family. I attended the University of Houston – Main Campus for my bachelor’s degree, and I completed my medical training (medical school and my pediatric residency) in the large Texas Medical Center in Houston. In 2023, I moved back to Clear Lake so that I could give back to this wonderful community.

I have a wonderful husband, and we are lucky to have both our families and fur-siblings in the area. My hobbies include playing tennis (when it’s not too hot outside), playing the piano, and spending quality time with family and friends.

Pediatrics has been my calling since high school. I am blessed to have the opportunity to be able to educate and comfort patients and their family members in some of their most stressful times. I love that I get to watch these children grow from newborns into wonderful young adults and help them along the way.

Being a growing child (or even raising one) isn’t easy! Every patient brings their own story, challenges, and personality, and each of them has something to teach me. I just strive to be a positive light during their journeys and work to keep my patients safe, healthy, and happy.
