Meet Our Team

It truly takes a team to run a hospital that sees nearly 400 cases each week. Every member of our staff plays an important role in the care of your pet. If there is anything that we can do for you during your pet's stay with us, please do not hesitate to ask.

Without our team of talented and caring staff members, NorthStar VETS would not be able to sustain its operations. Our 70+ technicians, assistants and over a dozen receptionists are dedicated to serving you - our patients, clients and referring veterinarians - striving every day to not simply meet your expectations but exceed them.

Here are a few people you may meet along the way.
