Licensed, Board-Certified Pediatricians with Years of Experience
All of the physicians at Jefferson Pediatrics are licensed, board-certified pediatricians with more than 50 years of combined experience seeing patients firsthand.
Peter Bess, M.D.
I Grew up in Jefferson County and am a graduate of Fox High School. I attended college at Truman State University and medical school at St. Louis University. I completed my residency in Pediatrics through Southern Illinois University in 2010 and am board certified in general Pediatrics in 2018.
My wife and I have three children and one cat. I read a healthy amount of science fiction and fantasy, and have a passion for nerdy board games. I’ve made the Kessel run in less than 12 parsecs, and I know Han shot first.
Betty Cross, M.D.
I am a Kansas native. I grew up in Lawrence, Kansas, and earned a BA in Biology at the University of Kansas. I then attended KU Medical Center where I earned my M.D. in 1983. In 1986, I completed a pediatric residency at Baylor University in Houston, Texas. I have been practicing Pediatrics in the St. Louis area since then, and was delighted to have the opportunity to join Jefferson Pediatrics in 2009.
I am Board Certified in Pediatrics and am a Fellow of the American Academy of Pediatrics. I have received the Physicians Recognition Award from the American Medical Association.
I am a lifetime member of the Girl Scouts of America and have enjoyed volunteering with my daughter’s troop. I love the outdoors: camping, canoeing, gardening, hiking, and taking daily walks. I enjoy studying and working with gems and minerals, and I have used them in making jewelry.
Marsha Vedova, M.D.
I graduated from the Ohio State University School of Medicine and Public Health in 1998. I completed my residency training in Pediatrics at Cardinal Glennon Medical Center in 2001 and am board certified in General Pediatrics. I have been with Jefferson Pediatrics since 2002.
I grew up in rural Ohio, the youngest of seven children. I met my husband Mick in Cincinnati. We were married in 1994 and then moved to Missouri for my residency in 1998. The Vedovas, having two children both born after moving to the area, now call Missouri their home. Our family is very involved with Jubilee Church, St. Louis, as well as school, music and scout activities with our kids.
Jefferson Pediatrics participates in the COPE program through Children’s Hospital. In the program medical school graduates who are pediatric residents at Children’s Hospital join our practice for three years for one-half day each week. First, the residents shadow a principal physician and then eventually begin seeing patients on their own. By participating in the COPE Program, Jefferson Pediatrics helps give back to the medical community by training residents on the day-to-day activities associated with working in a practice dedicated to pediatrics.
