Dr. Gillian Haanen is from the Netherlands and graduated from Utrecht University. Following graduation, she worked as an intern at Sportpaardenkliniek Wolvega in the Netherlands, Moore Equine in Canada, and Purdue University in the United States. She developed a love for all things internal medicine and started a Large Animal Internal Medicine Residency at Purdue University in 2016.

Besides horses, she has worked with cattle, sheep, goats, pigs, and camelids, which she enjoyed very much!

Dr. Haanen completed her residency training in 2019. We are happy to announce that she has returned to Moore Equine with a special focus on internal medicine and hospitalized patients. Her interests within the field of internal medicine are neonatology, gastrointestinal, respiratory, and infectious diseases.

In her free time she enjoys the Rocky Mountains, from hiking in the spring time to snowboarding during the winter months.
