Helen and Arthur E. Johnson Animal Hospital

World-Class Care for Our Animal Family

The 22,000-square-foot Helen and Arthur E. Johnson Animal Hospital offers two treatment rooms, critical care units and a cutting-edge surgical suite—all supported by the most technologically advanced equipment in the industry. From the tiniest tree frog to a full-grown grizzly bear, every one of our animals is able to receive the care they need. The state-of-the-art hospital features a lobby of viewing windows in the Schlessman Family Foundation Visitor and Education Center, which is open daily from 9 a.m.–4 p.m. On any given day, guests may be able to view the medical care that is critical to the well-being of Denver Zoo’s animals. If the treatment rooms are not in use, interactive video displays and staff facilitators educate guests on the many procedures, treatments and surgeries we perform each year to ensure our animals thrive. 

NOTE: Due to the unpredictable nature of medicine and the work being conducted in the hospital, we are unable to provide advance notice of upcoming procedures or guarantee that you will see a live procedure during the time of your visit. Generally, weekdays before 11 a.m. are the best days to try to catch a procedure, but there is never a guarantee.
