Airport Animal Hospital was founded and opened by Dr. Tom Hohl in 1979.  Dr. Hohl worked long and hard to build a quality veterinary practice and was effective in earning the trust of a loyal client base.  Dr. Paul Fitzgerald joined Dr. Hohl as an associate in July, 2000.  In July, 2003, an ownership transition was made and Dr. Fitzgerald took over operations of the practice.  After several years of rapid growth Dr. Leslie Clapper-Rentz joined August, 2005.  After Dr. Hohl’s retirement Dr. Mary Wictor joined the practice in the fall of 2013.  Continued growth and success inspired a complete remodel and expansion of the hospital completed late July of 2018.  In early 2019 Dr. Melissa Frank and Dr. Kristi Costley joined the practice.  Together this group of compassionate and talented veterinarians, along with our wonderful support staff, have helped Airport Animal Hospital grow into the busy and reputable veterinary practice that it is today.
