Our Physicians

Joshua Smith, M.D.


As Dr. Smith was growing up on a Southern Illinois farm, he was always fascinated by science and wanted to become a physician at an early age. He was more drawn to this thought when he found out how hard farm work was and has not looked back since. Becoming a pediatrician was a choice made in medical school: being around kids all day and seeing sick kids become well was fulfilling for him. After graduating from Southern Illinois University School of Medicine in 2004 and completing a pediatrics residency at Cardinal Glennon/St. Louis University in 2007, Dr. Smith joined Brentwood Pediatrics. He has enjoyed seeing newborns grow into young children since that time and loves to serve his patients and their families.

Dr. Smith is married to a beautiful and patient woman who lovingly raises their two children. During time away from practicing medicine, he spends time with his family, is involved in his local church, watches sports, reads, and exercises when he can.

Jean E. Birmingham, M.D.


Dr. Birmingham grew up in St. Louis and knew she wanted to be a doctor while still in high school.  She attended college at Ohio Wesleyan University from 1980-1984, graduated magna cum laude and became a member of Phi Beta Kappa.  She returned to Missouri for medical school at the University of Missouri-Columbia from 1984-1988.  After choosing a career in pediatrics, she did her internship and residency at Children’s Mercy Hospital in Kansas City.  She started practice in St. Louis in 1991 and is Board Certified by the American Board of Pediatrics.  She is a fellow of the American Academy of Pediatrics and was selected as a Top Doc by St. Louis Magazine multiple years.

Dr. Birmingham is married and the very proud mother of an awesome pre-teen.  In her rare free time she enjoys biking, her book club and baking.

Susan E. Adams, M.D., PhD


Dr. Adams grew up in a small town in eastern Kansas, the third daughter of a family practice physician and a homemaker who obtained a degree in library science after her children left for college.  She decided to become a doctor in fifth grade after watching her great-uncle’s decline and passing, feeling that her life’s work could help with easing such burdens on patients and their families.  In college she took a detour and chose to attend graduate school obtaining Ph.D. in microbiology.  She spent four years at Columbia University Medical Center in New York City working on a post-doctoral fellowship before deciding to return to her true interest.  She attended medical school at Washington University in St. Louis and completed residency training at St. Louis Children’s Hospital in 1994.  She has been in private practice since.

Outside of the office she has many interests.  She plays the oboe and English horn in the St. Louis Wind Symphony and the University City Summer Band.  She is active in her church, currently singing in the chancel choir and a small outreach group, the Covenant Chorus.  She has also performed in duets and a few solos in church.  She loves baseball and attends a number of St. Louis Cardinals games each summer.  She enjoys frequent performances at the Repertory Theater and the St. Louis Symphony.  She has recently developed an interest in Opera Theater while opening her house to performers during their time in St. Louis.  She tries to garden, but confesses that she has more of a brown than a green thumb.

After losing Sheba, her beloved canine companion of sixteen years, she has adopted two rescue cats—Tiger and Chip.  They bring her much love, joy and laughter.

Dear Dr. Adams,
Many thanks for your "long distance doctoring" of our son's poison ivy while we were in Kentucky. The pharmacist in Liberty couldn't say enough about you. We all think that Devin is very lucky to have you as his doctor.
Dear Dr. Birmingham,
We want to thank you again for your dedication and personable care of our three children and us, the parents.  We feel we have the best doctor possible and that makes our job/life much calmer and happier - we admire your warm personal care.
Dear Dr. Smith,
We want to thank you for your time and attention when you sent our child to the ER.  We knew you felt our complete terror.  You kept in contact with the ER doctor and helped make the right decision for our child.  Your knowledge and kind way has sealed our family's healthcare decision.  You are truly a partner in our children's health.
