Kareb Melnyk webKaren Melnyk
City of Edmonton
Karen Melnyk graduated from the Animal Health Technology program at NAIT in 1996, and has worked in the shelter medicine field ever since. One of Karen’s passions is making the world a better place for companion animals and their humans. Through her years of experience, she has become very aware of the growing impact that compassion fatigue is having on workers in animal shelters and veterinary medicine. The need for a dedicated resource to help deal with this animal-related compassion fatigue is one reason Karen joined this national committee. She is married, has two sons, and is a dedicated hockey mom. In her spare time, Karen loves to go camping with her family, and rescue Devon Rex cats.


Kim Marosevich webKim Marosevich, Bylaw Business Operations Manager for the City of Surrey and BC/Yukon Representative of Aussie Rescue Placement Help (ARPH)
Kim’s career started in the halls of the Toronto Humane Society in 1999. She has had the pleasure to work just about every job one can in a shelter outside of the veterinary roles. Many lifetime friends have been made through animal sheltering work and rescue volunteering. She currently shares her life with three dogs, one cat and a husband who she also met in the shelter. Who better to understand when she arrives home with yet another foster something?
