Dr. Katherine Abbott

She formed Crestwood Pediatric Associates in 1993. Since this time the practice has grown to encompass a staff of five pediatricians and added a second office location in the Gainesville/Haymarket area. Her interests include the education and support of new parents and breast feeding, education on the benefits of vaccination, and fighting our growing problem of childhood obesity. She is also very interested in maintaining an active affiliation with the regional hospitals. She helped start the in-house hospitalist program at Prince William Hospital, started the Pediatric Grand Rounds program at Prince William Hospital, and served for several years as Chairman of the Physician Credentialing Committee at Prince William Hospital.

Dr. Abbott has been recognized as a Top Doctor in the Washingtonian almost every year since 2005 and in the Northern Virginia Magazine since 2013. She currently lives in Chantilly, Virginia with her husband and two of their six children. The first four have completed college and two have started families of their own. In all aspects of her life, she is devoted to children. "So much of the advice I give to my patients and their parents comes from having been there and done that myself."
