Dr. Ivanov

Education: National University of Colombia, Iowa State University
Dr. Ivanov, the owner of the practice, has been an integral part of Norbeck Animal Hospital since 2004. Originating from Colombia, he earned his veterinary degree and spent four years as a professor before relocating to the USA in 2000. Dr. Ivanov furthered his education at Iowa State University, obtaining Title Equivalence, and pursued an internship in Medicine and Surgery of Small Animals at The Ohio State University.
Passionate about veterinary medicine, Dr. Ivanov assumed ownership of the practice in 2007. His journey in the field began with a love for animals and a desire to serve the community. Over the years, he has cultivated a deep connection with the clientele and their pets, considering them an extension of his own family.
For Dr. Ivanov, being a veterinarian is a calling that he recognized early on. Whether practicing veterinary medicine or managing his coffee farm, Cafe Tio Conejo, in Colombia, he feels fortunate to be engaged in what he loves most. Outside of the clinic, his dedication to coffee cultivation reflects in the success of Uncle Rabbit Coffee (Cafe Tio Conejo), a business that has become synonymous with his commitment to quality and excellence.

Dr. David
DVM
Education: University of Maryland, Virginia-Maryland Regional College of Veterinary Medicine
Dr. Tuthill grew up in College Park, MD, and attended the University of Maryland where he earned his Bachelor’s degree in Biochemistry in 1982. He then attended the Virginia-Maryland Regional College of Veterinary Medicine from 1984-1988, earning his Doctorate in Veterinary Medicine. Dr. Tuthill has devoted much of his professional career to the practice and study of emergency medicine. After a couple years in mixed animal practice, he started working full-time as an emergency vet and found he enjoyed the excitement and challenges of emergency medicine and surgery. During this time he also engaged in research activities with the National Zoo and the National Institutes of Health where he performed laparoscopic artificial insemination of exotic small Asian Leopard Cats for a genetic mapping project. In addition to his many years in both emergency and family veterinary practice, he spent ten years in research and academia: first as a Scientist for the American Red Cross with a special focus on trauma and wound healing; and later as a Biology Professor at Kent State University where he taught microbiology and physiology to nursing and pre-med students. Most recently, Dr. Tuthill owned and operated an emergency hospital in Prince George’s County for 7 years. After closing this clinic, he joined us as a part time relief doctor, and he liked the staff and the clientele so much here at Norbeck that he decided to come on board with us full-time, and we feel lucky to have him. Dr. Tuthill and his wife, Sheila, have 3 boys. His four legged family members consist of an old black Lab named Molly, a Tuxedo cat named Noche, and two guinea pigs, Jasper and Barnaby. His main hobby is music; he plays a little jazz and blues on the piano and guitar.
