Client Care Specialist - Part Time

As a client of ours growing up, Katie always knew she wanted to work with animals and people. After years of customer service positions she graduated from the Veterinary Administrative Assistant program at NAIT in May 2009. After completing her practicum with us in April 2009 she was more than excited to come back to us full time in June that same year. You can find her all over the clinic; from helping clients at front reception to assisting the technicians when ever she is needed. Katie is very proud and thankful to be apart of such a great team!

Jacqueline started with Greenbank Veterinary Services in August 2016. She had been coming to the clinic for a few years with her own pets and is thrilled to be working with not only two amazing doctors, but staff as well. As a client and now an employee, she is truly thankful for this wonderful opportunity for the work that she does and to be greeted by so many dogs and cats every day that all touch her heart in their very own special way.

Frank was born February 16, 2012 and at 8 weeks old was adopted by Michelle. He has been coming with her to the clinic every working day since.  He can usually be found in the basket or the in-box on the front reception desk guarding the treats close by.  Frank also loves to sun bathe on the reception chairs and greet the cats when they arrive for their appointments.
