We Care for Your Kids


About Us

Our doctors see patients from newborn to age 18 years. Formed in 2017, Mansfield Pediatrics PLLC is an independently owned and operated pediatric practice. We have been in the Mansfield community as independent physicians since 2002. Marcia Sampson, M.D. was the founding physician of the practice. We have changed and grown from our original home on Highway 157 to our new building on Cannon Drive with five physicians and one nurse practitioner. Our goal is to continue to grow and become a part of the Mansfield, Texas, community for years to come.

Dr. Huan Pham

Dr. Huan Pham is the youngest in his immigrant family, who moved from Vietnam to Arlington, TX, at the age of 2. There, he grew up and received much of his education, including his Bachelor of Science degree, at UT Arlington. He always wanted to choose a meaningful career that would allow him to dedicate his love and appreciation to his parents; thus, he ultimately chose medicine. He pursued this dream by attending medical school at UNT Health Science Center in Ft. Worth, TX.

His love for pediatrics blossomed due to his extensive experience as a soccer coach. He believes that the kids he coached paved the pathway toward pediatrics. With this in mind, Dr. Pham completed his residency training at Oklahoma University Children’s Hospital in Oklahoma City.
