Clinic Staff- Meet our team!

Dr. Jennifer Schaefer

Dr. Schaefer received her Bachelor’s degree in Animal Sciences, her Master’s degree in Public Health-Veterinary Public Health, and Doctor of Veterinary Medicine Degree from The Ohio State University.  Dr. Schaefer began her veterinary career in 2003 when she began working as a veterinary assistant and volunteering at Franklin County Dog Shelter.  Her passion for behavior and rescue began at the same time while mentoring under a veterinary behaviorist.  Both during and after veterinary school, Dr. Schaefer has sought out electives and continuing education in both behavior and shelter medicine. 


After graduating with her Doctor of Veterinary Medicine in 2012, she began her service in the United States Army.  She served her three year tour in Fort Irwin California where she ran a veterinary clinic that saw both military members privately owned pets as well as Military Working animals (dogs, horses, goats, and burros).  She even got to see a few Desert Tortoises which are an endangered species!  Dr.  Schaefer was also in charge of a small shelter that served the Fort Irwin community.  While there she was instrumental to changing garrison policy on microchipping and registering pets to reduce the number of free roaming animals.  She also greatly helped reduce the number of euthanized animals by working closely with several private rescue groups in the surrounding communities. 


When choosing to leave the Active Army, Dr. Schaefer moved back to Ohio with her husband and 2 children to be closer to family.   She originally began working for a private clinic in Upper Sandusky doing mostly small animals with some large animal/equine work.  When her dream job became available at HSDC she was excited to join such a wonderful organization.  In her spare time she participates in the Army Reserves as well as taking care of 3 dogs, 2 cats, and 3 horses.

Dr. Sue Zinni, DVM

4-H cultivated Dr. Sue Zinni’s love and desire to care for all animals and inspired her to pursue a career in Veterinary Medicine. Dr. Zinni graduated in 1990 from The Ohio State University, College of Veterinary Medicine. She owned and operated a veterinary hospital in New Albany, OH for 26 years until she sold it in 2011. The hospital was a full service care facility including medical, surgical, radiology, dental, nutritional, behavioral, obedience classes, grooming and boarding. Strays or surrendered pets were always available for adoption at her clinic. Before that, Dr. Zinni was a Registered Veterinary Technician and worked around her home town of Rayland for 4 years until her acceptance into Veterinary school. After her retirement, she started working part time at HSDC in 2013.

Dr. Zinni lives in New Albany with her two rescued dogs from her clinic, 2 shelter cats, a rabbit from HSDC, and a rescue horse from the slaughterhouse auction.
