With over 19 years of experience in avian and exotic clinical practice, laboratory diagnostics and pathology, Drury is skilled in the medicine and surgery of birds, reptiles, amphibians, fish, insects, and a wide variety of exotic mammals.

Drury graduated from Colorado State University’s College of Veterinary Medicine in 1986 then took an associate position at the Avian Medical Center of Sacramento where she practiced for more than 8 years. During this time Drury also did relief work for other exclusively exotic animal practices and provided clinical consultation and laboratory services to practitioners through California Avian Laboratory (a national service exclusively devoted to avian and exotic animals) as well as through California Veterinary Diagnostic Labs of West Sacramento.

Starting in 1995 Drury began her pathology training under Dr. Schmidt’s guidance. She completed her residency in anatomic pathology (including instruction in zoo pathology and course work at the Armed Forces Institute of Pathology) and gained board certification from American College of Veterinary Pathology (ACVP) in 2000. Drury is also a charter Diplomate of the American Board of Veterinary Practitioners, obtaining avian specialty status in 1993 and re-certifying in 2003.

Drury has authored or co-authored over 30 papers, 10 book chapters, one book and a CD, each covering a wide range of exotic animal disease conditions. She is a popular presenter on-line through VIN and at veterinary conferences, veterinary schools, and meetings in the United States and around the world.
