COVID-19 Updates
We are reopening our lobby! Beginning Wednesday, May 11th, we will be welcoming clients and their pets back into our waiting room.

We will still be offering curbside service for clients who prefer to wait in their car. Please call the hospital when you arrive in our parking lot.

If you are not feeling well, have any flu-like symptoms, or you or your pet have been exposed to a suspected or confirmed case of COVID-19, please let us know prior to your appointment. Your continued support, patience, and understanding are extremely appreciated as we remain committed to helping our patients and their families.
