Meet Dr. Marcus S. Ozaeta
For Marcus Ozaeta, M.D., the decision to become a doctor was made in high school. He volunteered at a hospital while attending Jesuit High School in Dallas and spent his summer at a nursing home facility to introduce himself to the field of medicine.? He attended Boston College in Chestnut Hill, MA graduating cum laude in the Honors Program with a Bachelor of Science degree in Biology. He received his medical degree from the University of Texas Medical School in Houston.
It was during his third year in medical school that after finishing a clinical rotation in pediatrics that he decided on becoming a pediatrician. The vocation of caring for patients from infancy to young adulthood appealed to him very much. Moreover, pediatrics suited his personality since he is a self-described "kid at heart."
Dr. Ozaeta completed his pediatric residency at the University of Texas Health Science Center, also in Houston. He is board certified with the American Board of Pediatrics. Prior to joining Cook Children's in 2003, he practiced with Las Colinas Pediatric Association in Irving, Texas.
Aside from caring for his patients, Dr. Ozaeta enjoys spending time with his family. He is married to Dr. Rebecca Olvera and they both enjoy seeing patients at Cook Children's Clearfork. They are also? blessed with 2 spontaneous sets of twins, identical boys in 2004 and fraternal girls in 2009. He likes to read and is a sports and fitness enthusiast.
Dr. Ozaeta is an amazing doctor. He always knows what's going on with not only one of my children but both of the twins he's able to keep them separate and know both of their medical history. He's very detailed. I never have to wait long and I can always get an appointment. – Patient family

The nurse that helped us was fantastic. My son was very nervous about getting a flu vaccine - they usually are not available yet when he goes in for his yearly well check up, so I had not prepared him that he would be getting a shot. The nurse was so kind, helpful, and quick. She was phenomenal! Dr. Ozaeta has been amazing since we first saw him with our son as a newborn (now 8!). He has always been a good listener and very kind. As a newborn we were waiting on test results for jaundice and he called us late in the evening just to let us know he still didn't have the results. As anxious first time parents, this meant a lot to us. We drive 25 minutes to still see Dr. Ozaeta because of the care, concern, and kindness he showed us over 8 years ago (and continues to show us!).
