Dr. Holwitt is a board-certified, fellowship-trained breast surgeon, with sub-specialty training in breast surgical oncology. At age 36, she was diagnosed with breast cancer and underwent a double mastectomy and chemotherapy. This unique situation makes her a more understanding doctor and an advocate for all who look to her for treatment. She has walked in their shoes. Most importantly, since her diagnosis, Dr. Holwitt is passionate about spreading the word on the importance of early detection. She has been actively involved in professional and community efforts to promote breast health awareness and survivorship support.

Dr. Holwitt graduated cum laude from Colgate University and earned a medical degree from Virginia Commonwealth University/Medical College of Virginia, where she was elected to the Alpha Omega Alpha Medical Honor Society. During her residency, also at Virginia Commonwealth University, she was elected Surgical Intern of the Year and won the Basic Science Research Award. After completion of a general surgery residency, she did a Fellowship in Breast Surgical Oncology at Washington University School of Medicine in St. Louis. As a Fellow in breast surgical oncology, she was invited to deliver two presentations at the 2008 American Society of Breast Surgeons Meeting and was awarded the Best Scientific Presentation Award for manuscripts that were published in the American Journal of Surgery in May 2009.
