Dr. Dietz was born in Manhattan and moved to Merrifield, VA, then Norfolk, VA, and then Cincinnati, OH, before settling back to Northern Virginia again at age 8. She finished 4th-12th grades in Fairfax County Public Schools. She went to college at Duke University where she majored in English and took a job with an archaeological magazine out of college. However, she is from a family of physicians and going to medical school had always been a consideration. She changed course and pursued the requirements and went to medical school at age 25. She then came back to this area to do her Internal Medicine residency at Georgetown University. She then worked in private practice in Internal Medicine in Alexandria Virginia.

Along the way in this journey, she also competed in the Chesapeake Bay Bridge Swim race multiple times, completed an Iron Man Canada race, and completed a Brevet Randonneuring bicycling series (which ends with riding 360 miles in 36 hours). She got married in 2004 and moved to Ann Arbor, Michigan, with her husband. She worked there on staff with the University of Michigan in their primary care group. She and her husband had a daughter in 2010 and subsequently moved back to Arlington, VA, to be closer to family. With life completely changed with their new daughter, so did Dr. Dietz’s outlook on practicing medicine. She found herself quite interested in pediatrics and adolescent medicine. She is now very happily working with the accomplished Dr. Barbara Stevens, seeing adolescent patients and young adults up to age 21.
