Our Doctors

Dr. Taddeo

Dr. Brenda Taddeo

Dr. Taddeo is the owner of Sully Animal Hospital. She comes from northern Michigan, and because of the frigid winters, she decided to go south to complete her undergraduate degree and found herself at High Point University. She attended Ross University School of Veterinary Medicine and completed her clinicals at Purdue University College of Veterinary Medicine.

After graduating, she moved to northern Virginia with her husband, who is native to the area. Dr. Taddeo has practiced with the Northern Virginia Veterinary Associates and primarily worked at Chantilly and Centreville Square Animal Hospitals. She also practiced at Prince William Emergency Veterinary Clinic in Manassas, where she was able to gain critical patient care experience. Dr. Taddeo enjoys surgeries and has one of the best recovery rates in the D.C. metro area.

Dr. Taddeo lives in Fairfax, Virginia., with her husband and three girls. They have two cats named Skitters and Kitt.

Dr. Taddeo believes that treatment does not stop with the diagnosis and a medical prescription. She feels that high-quality medicine and TLC are essential aspects of patient care. Dr. Taddeo prides herself on treating all of her patients as if they were her own.
