Dr. Ann Hohenhaus is a third generation veterinarian with an extensive background and expertise in veterinary medicine including two specialty board certifications.

She has achieved board certification in both Oncology and Small Animal Internal Medicine by the American College of Veterinary Internal Medicine. In 2010, Dr. Hohenhaus was invited by Pfizer Animal Health to participate in their Frank Communications Program at the Argus Institute in Fort Collins, Colorado. This seminar trained veterinarians to use pet owner centered communications when discussing medical issues in the examination room.

Later that year, Dr. Hohenhaus completed a 6-year term on the American Veterinary Medical Association’s Council on Research, serving as the Council Chair during the final year of her term.

She has continuously practiced clinical veterinary medicine, almost exclusively at The Animal Medical Center and has contributed to all facets of its tripartite mission of clinical service, research and teaching. In her AMC clinical practice, Dr. Hohenhaus provides primary care to long-term patients and specialty care to pets with cancer and blood disorders. Her medical philosophy when treating cancer in pets is to use multimodality therapy to control tumor symptoms while improving the quality and quantity of life for dog and cat cancer patients. 

In addition to participating in The AMC’s continuing education programs for graduate veterinarians, Dr. Hohenhaus has participated in national and international continuing education programs, including seven times at the ACVIM Forum and five times at the North American Veterinary Conference. In 2011, she was an invited speaker at the Deutsche Vereinigung fur Gestalttherapie in Berlin, Germany and in 2014 at Oncologisch Treffen in the Netherlands.  

Dr. Hohenhaus has written extensively on oncology and transfusion medicine and since 2000, she is listed as an author on 31 publications by Pub Med, for clinical research conducted on dogs and cats with spontaneously occurring diseases including: mast cell tumors, melanoma, osteosarcoma, exocrine pancreatic insufficiency and anemia. During the same time period, she also authored 13 textbook chapters in veterinary textbooks. Working with dozens of interns and residents in training at The AMC, Dr. Hohenhaus has had the privilege to advise young veterinarians on their career pathway, mentoring seven of them to award winning research projects. 

In addition to her clinical practice at The AMC, Dr. Hohenhaus serves as the hospital’s spokesperson and is frequently called upon by national media outlets to discuss timely and relevant issues related to veterinary medicine. Furthermore, she writes a pet owner educational blog for The AMC  and previously served as an AVMA expert and blogger in the WebMD Healthy Pets Community. Dr. Hohenhaus has also created content for nationally recognized publications such as Ladies' Home Journal.
