She completed her residency in Obstetrics and Gynecology at Pennsylvania Hospital in Philadelphia, where she received awards for both leadership and excellence in laparoscopic surgery. Although she enjoyed practicing both Obstetrics and Gynecology for several years, she now focuses on the complete gynecologic care of women. Prior to founding Women’s Health Specialists of Frederick in 2004, she also enjoyed teaching medical students and residents.

Dr. Parnes is an accomplished gynecologist with extensive experience in pelvic floor reconstruction, and minimally invasive hysterectomy.

Tanya-Schaffer-Dewitt-MDDr. Tanya Schaeffer DeWitt was the first female OBGYN physician in Frederick, arriving in 1987. After delivering scores of babies at FMH for 11 years, and having two babies herself, she relocated  to New Hampshire for family reasons. In New Hampshire, she was an Adjunct Associate Professor at the Dartmouth Hitchcock Medical Center, and continued an active practice on obstetrics and gynecology. She has been a fellow of the American Congress of Ob-Gyn for over 21 years.

An opportunity arose to return to this beautiful area, so she and her family returned to their farm in Middletown. Now, as a member of our staff, she never ceases to be surprised by  the number of  women  she has delivered in the area who seek to continue their gynecologic care with her as they raise their own families. Dr. DeWitt offers a full spectrum of gynecologic services and surgeries that address issues throughout a woman's enitre lifespan include including the in-office Essure procedure, colposcopy, and uterine ablations to treat heavy bleeding.
