Todd Driggers, DVM

Dr. Todd Eric Driggers grew up in a rural Indiana town, where loving animals through providing medical care became his passion. He started by caring for his pet dogs and cats as a boy, and progressed to exotic pets, such as his pet turtle named Tippy. Dr. Driggers was admitted to the Purdue University School of Veterinary Medicine after just two years of undergraduate study at Purdue, due to his commitment to the profession, demonstrated by his volunteerism and job at a small animal hospital in Indiana. Science, biology, and eventually medicine have been combined in his career as a practitioner of exotic animal medicine and surgery.

After graduating, he began working exclusively with exotic animals at the Avian And Exotic Animal Clinic in Indianapolis, and eventually moved to Arizona, where he started an exotic practice at Mesa Veterinary Hospital. He started a mobile practice called “Foothills Mobile Exotic DVM” in 1997 and changed the hospital name to “The Avian and Exotic Animal Clinic of Arizona” after moving into a small clinic.

He has spoken nationally and internationally at the Association of Avian Veterinary Conferences and the Association of Exotic Mammal Veterinarian Veterinary Conferences. He has also written several chapters in various peer-reviewed journals and books.

Dr. Driggers vacations in exotic locations around the world to view and learn about the wildlife he treats at the office. He is involved in many other activities outside work, including medical coordination for medical mission trips to the Dominican Republic through Food for the Hungry and child sponsorship advocacy. Dr. Driggers is a busy father of three and husband to his high school girlfriend, Heather. He and his family attend church at Central Christian Church in Gilbert.

After graduation, she completed two academic internships at the Louisiana State University (LSU) School of Veterinary Medicine. Her last year at LSU was entirely devoted to companion exotic, native wildlife and zoo/aquarium medicine and surgery. Dr. Scagnelli is extremely passionate about reptile medicine and conservation. She is an active member of the International Iguana Foundation, an organization that conducts health assessments and creates species survival plans for the world’s most endangered lizards. Dr. Scagnelli is also passionate about aquatic animal medicine and has conducted research on anesthesia methods in fish. She has published several peer-reviewed journal articles and book chapters on various topics relating to exotic animal medicine. While it may seem like Dr. Scagnelli only enjoys "scaly" critters, she loves all aspects of companion exotic medicine. Other areas of interest include backyard poultry and waterfowl medicine, raptor medicine, and avian orthopedic surgery and endoscopy. When she is not at the clinic, Dr. Scagnelli tries to spend her time outdoors or traveling, when possible. She can be found hiking, backpacking, rock climbing, kayaking, SCUBA diving, or simply gardening in the yard. She lives with her fiancé Mark, and numerous scaled, feathered, and furry critters.

Ryan Navarro, DVM, MS

Dr. Ryan Navarro is the newest veterinarian to join the AEAC family after completing a one year specialty internship with Broward Avian and Exotic Animal Hospital located in Deerfield Beach, FL. Prior to this, he earned both DVM and Master’s degrees from Ross University School of Veterinary Medicine in 2018 and 2016, respectively.

Dr. Navarro loves his work treating exotic animals and thrives on the variety of species he gets to interact with everyday. Professionally he enjoys all aspects of exotic veterinary medicine and has particular interests in wildlife conservation and infectious disease, having published several papers on gastrointestinal viral infections in several species from the Caribbean.

When not busy treating his patients, Dr. Navarro enjoys spending time outdoors. Kayaking, hiking, SCUBA diving, and snorkeling are among his favorite activities, in addition to “two wheel therapy sessions” with his Triumph Speedmaster. He lives with his fiancé Krystal, two budgies named Hanalei and Molokai, and three cats named Dr. Ana Taco, Professor Cheddar Cheese Pizza, and Merlin Lord of the Fleas.

Tim Cota, Veterinary Technician

Tim has had a lifelong passion for a wide variety of animals. From a very young age, he has had many reptiles and invertabrates that he has kept and bred. He has been a Veterinary Technician for ten years, and has contributed to many entomological studies involving scorpions, tarantulas, and many other small arachnids such as mites and pseudoscorpions. In his freetime, he likes to shoot portrait photography and spend time with his wife Andrea and 5 year old daughter Zoey, going camping, hiking, and looking for reptiles and bugs to photograph.

Samantha DeMarco, Veterinary Technician

Samantha was born and raised in Gilbert, Arizona, graduated from Perry High School, and received an athletic scholarship to play goalkeeper for Northern Arizona University’s Women's Soccer Team where she studied biology and herpetology. She has always had a passion for animals, especially reptiles, and ever since she was little, Samantha and her dad would go hiking looking for wildlife, especially native rattlesnakes. Ever since then she has wanted to work with exotics and wanted to be in the veterinary field. At 22 years-old, Samantha just recently bought her first house last October in Maricopa, Arizona. Samantha spends much of her time outside of AEAC working with green anacondas, Argentine boas, caiman lizards, and native rattlesnakes primarily. In addition to this variety of reptiles, she does share her home with several other critters as well including her dog Baily whom she raised from 5 weeks old. Samantha's “free” time is spent working with socializing Wolf dogs and educating the public regarding these amazing animals.
