Meet the Wise Owl Veterinarians

Dr. Sir Joel Joseph DVM, BS VS


Dr. Joseph wanted to be a veterinarian since he was 6 years old.  He is one of a handful of students who achieved a Bachelors Degree in Veterinary Science (BS VS) as a 1986 graduate of Michigan State University College of Veterinary Medicine. Dr. Joseph first established Wise Owl Animal Care using his jeep to provide house call services. Wise Owl soon grew into a full “hospital on wheels” including X-rays, surgery, dental, laboratory and ultrasound equipment in 2 motorhomes.  As his popularity grew, the mobile clinic was expanded into Wise Owl Animal Hospital, the Michigan Exotic Animal Specialty Services and the Center for Advanced Ferret Care (a USDA approved research and teaching facility). 

Moving to Guam in 2001, Dr. Joseph worked as a relief vet for many of the clinics as well as the US Military; becoming the primary veterinarian for the opening of the first military pet quarantine on island. Dr. Joseph soon established Wise Owl Animal Hospital in Guam. Once again he started out doing house calls and working for The Southern Comfort Zoo and Ranch in Merizo, Guam. The new Guam Wise Owl Animal Hospital has brought high quality, low cost veterinary care to the island’s pets and residents.

Dr. Joseph has also been very active in bringing veterinary care to remote places where previously none existed.  He has worked at free clinics in Nicaragua, Dominican Republic, St. Croix, Palau, Fiji, and many other places (42 Pacific Islands and counting).  In 2002 he established a clinic in Pohnpei, FSM. This flourished into a Non-profit NGO – Pacific Islands Veterinary Service – servicing The Marshall Islands, Pohnpei, Chuuk, Kosrae, and Yap.     

Dr. Joseph’s favorite sport is white water rafting and he can be found doing extreme sports including bungee jumping, canyon swings, mountaineering,  zip lines, quad riding, parasailing, ballooning, spelunking, and more.  Though he enjoys his daily beach walks/swims with his dog Cheyenne most of all.
