Kim Rennewanz 
Practice Manager

Kim joined the team at Willow Run in April of 2018; she has been working in the field of veterinary medicine for over 20 years.  Her career path has been very diverse, starting in private practice and expanding into Emergency/Critical Care Nursing, Internal Medicine and Oncology.  Kim left the hospital setting for a year and a half while working in the pharmaceutical industry monitoring the safety and efficacy of many well-known veterinary drugs; her work included drafting reports for submission to both the FDA and USDA.  As you can probably guess, Kim missed being part of the traditional hospital team and working directly with clients and their pets.  She returned to the clinic environment and became a Practice Manager in 2014. 

Kim fell in love with animals as a little girl and describes her husband as being “incredibly patient and understanding” despite her constant insistence that they have plenty of room for more pets (they don’t).  They have 2 daughters that are entirely too smart for their own good, and Kim is thrilled that they share the same passion for animals.  Her home would not be complete without Gwendalyn, her precious Pit Bull, 2 mixed breed dogs named Holly and Nicholas, and their very stubborn cat Mathilda.
